Update devel/fossil to 2.12.2

This includes security fixes.

Changes for Version 2.12.1 (2020-08-20)

    (2.12.1): Fix client-side vulnerabilities discovered by Max Justicz.
    Security fix in the "fossil git export" command. The same fix is \ 
also backported to version 2.10.1 and 2.11.1. New "safety-net" \ 
features were added to prevent similar problems in the future.
    Enhancements to the graph display for cases when there are many cherry-pick \ 
merges into a single check-in. Example
    Enhance the fossil open command with the new --workdir option and the \ 
ability to accept a URL as the repository name, causing the remote repository to \ 
be cloned automatically. Do not allow "fossil open" to open in a \ 
non-empty working directory unless the --keep option or the new --force option \ 
is used.
    Enhance the markdown formatter to more closely follow the CommonMark \ 
specification with regard to text highlighting. Underscores in the middle of \ 
identifiers (ex: fossil_printf()) no longer need to be escaped.
    The markdown-to-html translator can prevent unsafe HTML (for example: \ 
<script>) on user-contributed pages like forum and tickets and wiki. The \ 
admin can adjust this behavior using the safe-html setting on the Admin/Wiki \ 
page. The default is to disallow unsafe HTML everywhere. Example.
    Added the "collapse" and "expand" capability for long \ 
forum posts. Example
    The "fossil remote" command now has options for specifying \ 
multiple persistent remotes with symbolic names. Currently only one remote can \ 
be used at a time, but that might change in the future.
    Add the "Remember me?" checkbox on the login page. Use a session \ 
cookie for the login if it is not checked.
    Added the experimental "fossil hook" command for managing \ 
"hook scripts" that run before checkin or after a push.
    Enhance the fossil revert command so that it is able to revert all files \ 
beneath a directory.
    Add the fossil bisect skip command.
    Add the fossil backup command.
    Enhance fossil bisect ui so that it shows all unchecked check-ins in between \ 
the innermost "good" and "bad" check-ins.
    Added the --reset flag to the "fossil add", "fossil rm", \ 
and "fossil addremove" commands.
    Added the "--min N" and "--logfile FILENAME" flags to \ 
the backoffice command, as well as other enhancements to make the backoffice \ 
command a viable replacement for automatic backoffice. Other incremental \ 
backoffice improvements.
    Added the /fileedit page, which allows editing of text files online. \ 
Requires explicit activation by a setup user.
    Translate built-in help text into HTML for display on web pages. Example.
    On the /timeline webpage, the combination of query parameters \ 
"p=CHECKIN" and "bt=ANCESTOR" draws all ancestors of CHECKIN \ 
going back to ANCESTOR. For example, \ 
/timeline?p=202006271506&bt=version-2.11 shows all ancestors of the checkin \ 
that occured on 2020-06-27 15:06 going back to the 2.11 release.
    Update the built-in SQLite so that the "fossil sql" command \ 
supports new output modes ".mode box" and ".mode json".
    Add the "obscure()" SQL function to the "fossil sql" command.
    Added virtual tables "helptext" and "builtin" to the \ 
"fossil sql" command, providing access to the dispatch table including \ 
all help text, and the builtin data files, respectively.
    Delta compression is now applied to forum edits.
    The wiki editor has been modernized and is now Ajax-based. The WYSIWYG \ 
editing option for Fossil-format wiki pages was removed. (Please let us know, \ 
via the site's Support menu, if that removal unduly impacts you.) This also \ 
changes the semantics of the wiki "Sandbox": that pseudo-page may be \ 
freely edited but no longer saved via the UI (the wiki CLI command can, though).
    Countless documentation enhancements.
