git: updated to 2.18.0

2.18.0:

UI, Workflows & Features

 * Rename detection logic that is used in "merge" and \ 
"cherry-pick" has
   learned to guess when all of x/a, x/b and x/c have moved to z/a,
   z/b and z/c, it is likely that x/d added in the meantime would also
   want to move to z/d by taking the hint that the entire directory
   'x' moved to 'z'.  A bug causing dirty files involved in a rename
   to be overwritten during merge has also been fixed as part of this
   work.  Incidentally, this also avoids updating a file in the
   working tree after a (non-trivial) merge whose result matches what
   our side originally had.

 * "git filter-branch" learned to use a different exit code to allow
   the callers to tell the case where there was no new commits to
   rewrite from other error cases.

 * When built with more recent cURL, GIT_SSL_VERSION can now specify
   "tlsv1.3" as its value.

 * "git gui" learned that "~/.ssh/id_ecdsa.pub" and
   "~/.ssh/id_ed25519.pub" are also possible SSH key files.
   (merge 2e2f0288ef bb/git-gui-ssh-key-files later to maint).

 * "git gui" performs commit upon CTRL/CMD+ENTER but the
   CTRL/CMD+KP_ENTER (i.e. enter key on the numpad) did not have the
   same key binding.  It now does.
   (merge 28a1d94a06 bp/git-gui-bind-kp-enter later to maint).

 * "git gui" has been taught to work with old versions of tk (like
   8.5.7) that do not support "ttk::style theme use" as a way to query
   the current theme.
   (merge 4891961105 cb/git-gui-ttk-style later to maint).

 * "git rebase" has learned to honor "--signoff" option when \ 
using
   backends other than "am" (but not "--preserve-merges").

 * "git branch --list" during an interrupted "rebase -i" now lets
   users distinguish the case where a detached HEAD is being rebased
   and a normal branch is being rebased.

 * "git mergetools" learned talking to guiffy.

 * The scripts in contrib/emacs/ have outlived their usefulness and
   have been replaced with a stub that errors out and tells the user
   there are replacements.

 * The new "working-tree-encoding" attribute can ask Git to convert the
   contents to the specified encoding when checking out to the working
   tree (and the other way around when checking in).

 * The "git config" command uses separate options e.g. "--int",
   "--bool", etc. to specify what type the caller wants the value to
   be interpreted as.  A new "--type=<typename>" option has been
   introduced, which would make it cleaner to define new types.

 * "git config --get" learned the "--default" option, to help the
   calling script.  Building on top of the above changes, the
   "git config" learns "--type=color" type.  Taken together, \ 
you can
   do things like "git config --get foo.color --default blue" and get
   the ANSI color sequence for the color given to foo.color variable,
   or "blue" if the variable does not exist.

 * "git ls-remote" learned an option to allow sorting its output based
   on the refnames being shown.

 * The command line completion (in contrib/) has been taught that "git
   stash save" has been deprecated ("git stash push" is the preferred
   spelling in the new world) and does not offer it as a possible
   completion candidate when "git stash push" can be.

 * "git gc --prune=nonsense" spent long time repacking and then
   silently failed when underlying "git prune --expire=nonsense"
   failed to parse its command line.  This has been corrected.

 * Error messages from "git push" can be painted for more visibility.

 * "git http-fetch" (deprecated) had an optional and experimental
   "feature" to fetch only commits and/or trees, which nobody used.
   This has been removed.

 * The functionality of "$GIT_DIR/info/grafts" has been superseded by
   the "refs/replace/" mechanism for some time now, but the internal
   code had support for it in many places, which has been cleaned up
   in order to drop support of the "grafts" mechanism.

 * "git worktree add" learned to check out an existing branch.

 * "git --no-pager cmd" did not have short-and-sweet single letter
   option. Now it does as "-P".
   (merge 7213c28818 js/no-pager-shorthand later to maint).

 * "git rebase" learned "--rebase-merges" to transplant the whole
   topology of commit graph elsewhere.

 * "git status" learned to pay attention to UI related diff
   configuration variables such as diff.renames.

 * The command line completion mechanism (in contrib/) learned to load
   custom completion file for "git $command" where $command is a
   custom "git-$command" that the end user has on the $PATH when using
   newer version of bash-completion.

 * "git send-email" can sometimes offer confirmation dialog "Send this
   email?" with choices 'Yes', 'No', 'Quit', and 'All'.  A new action
   'Edit' has been added to this dialog's choice.

 * With merge.renames configuration set to false, the recursive merge
   strategy can be told not to spend cycles trying to find renamed
   paths and merge them accordingly.

 * "git status" learned to honor a new status.renames configuration to
   skip rename detection, which could be useful for those who want to
   do so without disabling the default rename detection done by the
   "git diff" command.

 * Command line completion (in contrib/) learned to complete pathnames
   for various commands better.

 * "git blame" learns to unhighlight uninteresting metadata from the
   originating commit on lines that are the same as the previous one,
   and also paint lines in different colors depending on the age of
   the commit.

 * Transfer protocol v2 learned to support the partial clone.

 * When a short hexadecimal string is used to name an object but there
   are multiple objects that share the string as the prefix of their
   names, the code lists these ambiguous candidates in a help message.
   These object names are now sorted according to their types for
   easier eyeballing.

 * "git fetch $there $refspec" that talks over protocol v2 can take
   advantage of server-side ref filtering; the code has been extended
   so that this mechanism triggers also when fetching with configured
   refspec.

 * Our HTTP client code used to advertise that we accept gzip encoding
   from the other side; instead, just let cURL library to advertise
   and negotiate the best one.

 * "git p4" learned to "unshelve" shelved commit from P4.
   (merge 123f631761 ld/p4-unshelve later to maint).

Log message:
git: updated to 2.17.1

Git v2.17.1:

Fixes:

 * This release contains the same fixes made in the v2.13.7 version of
   Git, covering CVE-2018-11233 and 11235, and forward-ported to
   v2.14.4, v2.15.2 and v2.16.4 releases.  See release notes to
   v2.13.7 for details.

 * In addition to the above fixes, this release has support on the
   server side to reject pushes to repositories that attempt to create
   such problematic .gitmodules file etc. as tracked contents, to help
   hosting sites protect their customers by preventing malicious
   contents from spreading.

Git 2.17:

UI, Workflows & Features
* "diff" family of commands learned \ 
"--find-object=<object-id>" option
  to limit the findings to changes that involve the named object.
* "git format-patch" learned to give 72-cols to diffstat, which is
  consistent with other line length limits the subcommand uses for
  its output meant for e-mails.
* The log from "git daemon" can be redirected with a new option; one
  relevant use case is to send the log to standard error (instead of
  syslog) when running it from inetd.
* "git rebase" learned to take "--allow-empty-message" option.
* "git am" has learned the "--quit" option, in addition to the
  existing "--abort" option; having the pair mirrors a few other
  commands like "rebase" and "cherry-pick".
* "git worktree add" learned to run the post-checkout hook, just like
  "git clone" runs it upon the initial checkout.
* "git tag" learned an explicit "--edit" option that allows the
  message given via "-m" and "-F" to be further edited.
* "git fetch --prune-tags" may be used as a handy short-hand for
  getting rid of stale tags that are locally held.
* The new "--show-current-patch" option gives an end-user facing way
  to get the diff being applied when "git rebase" (and "git am")
  stops with a conflict.
* "git add -p" used to offer "/" (look for a matching hunk) as a
  choice, even there was only one hunk, which has been corrected.
  Also the single-key help is now given only for keys that are
  enabled (e.g. help for '/' won't be shown when there is only one
  hunk).
* Since Git 1.7.9, "git merge" defaulted to --no-ff (i.e. even when
  the side branch being merged is a descendant of the current commit,
  create a merge commit instead of fast-forwarding) when merging a
  tag object.  This was appropriate default for integrators who pull
  signed tags from their downstream contributors, but caused an
  unnecessary merges when used by downstream contributors who
  habitually "catch up" their topic branches with tagged releases
  from the upstream.  Update "git merge" to default to --no-ff only
  when merging a tag object that does *not* sit at its usual place in
  refs/tags/ hierarchy, and allow fast-forwarding otherwise, to
  mitigate the problem.
* "git status" can spend a lot of cycles to compute the relation
  between the current branch and its upstream, which can now be
  disabled with "--no-ahead-behind" option.
* "git diff" and friends learned funcname patterns for Go language
  source files.
* "git send-email" learned "--reply-to=<address>" option.
* Funcname pattern used for C# now recognizes "async" keyword.
* In a way similar to how "git tag" learned to honor the pager
  setting only in the list mode, "git config" learned to ignore the
  pager setting when it is used for setting values (i.e. when the
  purpose of the operation is not to "show").

Performance, Internal Implementation, Development Support etc.
* More perf tests for threaded grep
* "perf" test output can be sent to codespeed server.
* The build procedure for perl/ part has been greatly simplified by
  weaning ourselves off of MakeMaker.
* Perl 5.8 or greater has been required since Git 1.7.4 released in
  2010, but we continued to assume some core modules may not exist and
  used a conditional "eval { require <<module>> }"; we no \ 
longer do
  this.  Some platforms (Fedora/RedHat/CentOS, for example) ship Perl
  without all core modules by default (e.g. Digest::MD5, File::Temp,
  File::Spec, Net::Domain, Net::SMTP).  Users on such platforms may
  need to install these additional modules.
* As a convenience, we install copies of Perl modules we require which
  are not part of the core Perl distribution (e.g. Error and
  Mail::Address).  Users and packagers whose operating system provides
  these modules can set NO_PERL_CPAN_FALLBACKS to avoid installing the
  bundled modules.
* In preparation for implementing narrow/partial clone, the machinery
  for checking object connectivity used by gc and fsck has been
  taught that a missing object is OK when it is referenced by a
  packfile specially marked as coming from trusted repository that
  promises to make them available on-demand and lazily.
* The machinery to clone & fetch, which in turn involves packing and
  unpacking objects, has been told how to omit certain objects using
  the filtering mechanism introduced by another topic.  It now knows
  to mark the resulting pack as a promisor pack to tolerate missing
  objects, laying foundation for "narrow" clones.
* The first step to getting rid of mru API and using the
  doubly-linked list API directly instead.
* Retire mru API as it does not give enough abstraction over
  underlying list API to be worth it.
* Rewrite two more "git submodule" subcommands in C.
* The tracing machinery learned to report tweaking of environment
  variables as well.
* Update Coccinelle rules to catch and optimize strbuf_addf(&buf, \ 
"%s", str)
* Prevent "clang-format" from breaking line after function return type.
* The sequencer infrastructure is shared across "git cherry-pick",
  "git rebase -i", etc., and has always spawned "git commit" \ 
when it
  needs to create a commit.  It has been taught to do so internally,
  when able, by reusing the codepath "git commit" itself uses, which
  gives performance boost for a few tens of percents in some sample
  scenarios.
* Push the submodule version of collision-detecting SHA-1 hash
  implementation a bit harder on builders.
* Avoid mmapping small files while using packed refs (especially ones
  with zero size, which would cause later munmap() to fail).
* Conversion from uchar[20] to struct object_id continues.
* More tests for wildmatch functions.
* The code to binary search starting from a fan-out table (which is
  how the packfile is indexed with object names) has been refactored
  into a reusable helper.
* We now avoid using identifiers that clash with C++ keywords.  Even
  though it is not a goal to compile Git with C++ compilers, changes
  like this help use of code analysis tools that targets C++ on our
  codebase.
* The executable is now built in 'script' phase in Travis CI integration,
  to follow the established practice, rather than during 'before_script'
  phase.  This allows the CI categorize the failures better ('failed'
  is project's fault, 'errored' is build environment's).
* Writing out the index file when the only thing that changed in it
  is the untracked cache information is often wasteful, and this has
  been optimized out.
* Various pieces of Perl code we have have been cleaned up.
* Internal API clean-up to allow write_locked_index() optionally skip
  writing the in-core index when it is not modified.
