Libification update (was: What's cooking in git.git (Aug 2024, #10; Tue, 27))

Hi folks,

Since we're no longer doing our regular libification sync
videoconference, I wanted to highlight recent developments related to
libification. These include:
* general code-health cleanups that make it easier to use Git as a
  library, such as leak fixes, error handling improvements, and
  reduction of global state
* unit testing, to get more coverage on Git internals
* explicit libification, i.e. exposing Git internals for use in other
  code bases

There are some interesting series which could use some more reviewers:
* Calvin's and my js/libgit-rust [1] to add a proof-of-concept Rust
  wrapper and API around Git internals
* Patrick's ps/clar-unit-test [2] to add the Clar [3] unit-testing
  framework
* Patrick's ps/leakfixes-part-6 [11] to fix various memory leaks
* Toon's series [12] to fix a leak in bundle-uri.c
* Ghanshyam's gt/unit-test-oidset [13] to add tests for oidset
* Ghanshyam's gt/unit-test-oid-array [15] to migrate testhelper tests to
  the unit-test framework

Other relevant series, which do not necessarily need reviewer attention
at the moment:
* Patrick's ps/leakfixes-part-5 [4], which is cooking in next

One stalled series, perhaps someone is interested in picking this up?
* Philip's pp/add-parse-range-unit-test [5], expecting a reroll

Finally, I'd like to celebrate a few series that have (or will soon)
graduate to master:
* gt/unit-test-urlmatch-normalization [6] to migrate testhelper tests to
  the unit-test framework
* cp/unit-test-reftable-block [7] and cp/unit-test-reftable-readwrite
  [9] to migrate reftable tests to the unit-test framework
* ps/config-wo-the-repository [8] to remove dependency on global state
  in path.c and config.c
* ps/leakfixes-part-4 [10] to fix various memory leaks
* rs/remote-leakfix [14] fixes memory leaks in git-remote

In the near future, we at Google (mostly just Emily, Calvin, and me) will be focusing on the next reroll of js/libgit-rust and reviewing other libification-related series.

Thank you to everyone who contributed with series and/or reviews!
