[ANNOUNCE] Git v2.47.1

The latest maintenance release Git v2.47.1 is now available at the usual places. This flushes some fixes accumulated on the 'master' front since Git 2.47.0 but the primary purpose is to synchronising "gitk" subtree with that of Johannes Sixt, who volunteered to be the new upstream maintainer of it. Huge thanks to Paul Mackerras who started the useful tool and have maintained it so far, and to Johannes Sixt to volunteering to move it forward.

The tarballs are found at:

Git 2.47.1 Release Notes ========================

This is to flush accumulated fixes since 2.47.0 on the 'master' front down to the maintenance track.

Fixes since Git 2.47 --------------------

 * Use after free and double freeing at the end in "git log -L... -p"
   had been identified and fixed.

 * On macOS, fsmonitor can fall into a race condition that results in
   a client waiting forever to be notified for an event that have
   already happened.  This problem has been corrected.

 * "git maintenance start" crashed due to an uninitialized variable
   reference, which has been corrected.

 * Fail gracefully instead of crashing when attempting to write the
   contents of a corrupt in-core index as a tree object.

 * A "git fetch" from the superproject going down to a submodule used
   a wrong remote when the default remote names are set differently
   between them.

 * The "gitk" project tree has been synchronized again with its new
   maintainer, Johannes Sixt.

Also contains minor documentation updates and code clean-ups.
