* "git log" learned a new "--diff-merges=<how>" option.
* "git ls-files" can and does show multiple entries when the index is
unmerged, which is a source for confusion unless -s/-u option is in
use. A new option --deduplicate has been introduced.

* The .use_shell flag in struct child_process that is passed to
run_command() API has been clarified with a bit more documentation.
* Document, clean-up and optimize the code around the cache-tree
extension in the index.
* The ls-refs protocol operation has been optimized to narrow the
sub-hierarchy of refs/ it walks to produce response.
* When removing many branches and tags, the code used to do so one
ref at a time. There is another API it can use to delete multiple
refs, and it makes quite a lot of performance difference when the
refs are packed.
* The "pack-objects" command needs to iterate over all the tags when
automatic tag following is enabled, but it actually iterated over
all refs and then discarded everything outside "refs/tags/"
hierarchy, which was quite wasteful.
* A perf script was made more portable.

* Our setting of GitHub CI test jobs were a bit too eager to give up
once there is even one failure found. Tweak the knob to allow
other jobs keep running even when we see a failure, so that we can
find more failures in a single run.

* We've carried compatibility codepaths for compilers without
variadic macros for quite some time, but the world may be ready for
them to be removed. Force compilation failure on exotic platforms
where variadic macros are not available to find out who screams in
such a way that we can easily revert if it turns out that the world
is not yet ready.
