notmuch: Update to 0.31

Changelog:
What's new in notmuch 0.31
=========================

Emacs
-----

Notmuch now supports Emacs 27.1. You may need to set
`mml-secure-openpgp-sign-with-sender` and/or
`mml-secure-smime-sign-with-sender` to continue signing messages.

The minimum supported major version of GNU Emacs is now 25.1.

Add support for moving between threads after notmuch-tree-from-search-thread.

New `notmuch-unthreaded` mode (added in Notmuch 0.30)

  Unthreaded view is a mode where each matching message is shown on a
  separate line.

  The main key entries to unthreaded view are

  'u' enter a query to view in unthreaded mode (works in hello,
      search, show and tree mode)

  'U' view the current query in unthreaded mode (works from search,
      show and tree)

  Saved searches can also specify that they should open in unthreaded
  view.

  Currently it is not possible to specify the sort order: it will
  always be newest first.

Notmuch-Mutt
------------

The shell pipeline executed by notmuch-mutt, which symlinked matched
files to a maildir for mutt to access is replaced with internal perl
processing. This search operation is now more portable, and somewhat
faster.

Library
-------

Improve exception handling in the library. This should
largely eliminate terminations inside the library due to uncaught
exceptions or internal errors.  No doubt there are a few uncovered
code paths still; please report them as bugs.

Add `notmuch_message_get_flag_st` and
`notmuch_message_has_maildir_flag_st`, and deprecate the existing
non-status providing versions.

Move memory de-allocation from `notmuch_database_close` to
`notmuch_database_destroy`.

Handle relative filenames in `notmuch_database_index_file`, as
promised in the documentation.

Python Bindings
---------------

Documentation for the python bindings is merged into the main
sphinx-doc documentation tree. The merged documentation can be built
with e.g. `make sphinx-html`

Dependencies
------------

We now support building notmuch against Xapian 1.5 (the current
development version).

Test Suite
----------

Test suite fixes for compatibility with Emacs 27.1.

Build System
------------

Man pages are now compressed reproducibly.

Log message:
notmuch: Update to 0.30

Changelog:
Notmuch 0.30 (2020-07-10)
=========================

S/MIME
------

Handle S/MIME (PKCS#7) messages -- one-part signed messages, encrypted
messages, and multilayer messages. Treat them symmetrically to
OpenPGP messages. This includes handling protected headers
gracefully.

If you're using Notmuch with S/MIME, you currently need to configure
gpgsm appropriately.

Mixed-up MIME Repair
--------------------

Detect and automatically repair a common form of message mangling
created by Microsoft Exchange (see index.repaired=mixedup in
notmuch-properties(7)).

Protected Headers
-----------------

Avoid indexing the legacy-display part of an encrypted message that
has protected headers (see
index.repaired=skip-protected-headers-legacy-display in
notmuch-properties(7)).

Python
------

Drop support for python2, focus on python3.

Introduce new CFFI-based python bindings in the python module named
"notmuch2".  Officially deprecate (but still support) the older
"notmuch" module.

Dependencies
------------

Support for Xapian 1.2 is removed. The minimum supported version of
Xapian is now 1.4.0.

Notmuch 0.29.3 (2019-11-27)
===========================

General
-------

Fix for use-after-free in notmuch_config_list_{key,val}.

Fix for double close of file in notmuch-dump.

Debian
------

Drop python2 support from shipped debian packaging.

Notmuch 0.29.2 (2019-10-19)
===========================

General
-------

Fix for file descriptor leak when opening gzipped mail files. Thanks
to James Troup for the bug report and the fix.

Notmuch 0.29.1 (2019-06-11)
===========================

Build
-----

Fix for installation failure with `configure --without-emacs`.

Log message:
notmuch: Reuse GPGME_GPG variable rather than inventing our own.

Not only cleaner, but also fixes a build issue seen on macOS likely related to
variable definition ordering, where GPG was not set correctly and ended up
trying to use a non-existent "gpg" command.  This change has the added \ 
benefit
of using the full path to the gpg binary instead of relying on PATH.
