[PATCH v5 0/3] Introduce Git Standard Library

[Calvin Wan <calvinwan@google.com>]

While it has been a while since the last reroll of this series[1], the
contents and boundaries of git-std-lib have not changed. The focus for
this reroll are improvements to the Makefile, test file, and
documentation. Patch 1 contains a small fix for a missing include
discovered by Jonathan Tan. Patch 2 introduces the Git Standard Library.
And patch 3 introduces preliminary testing and usage examples for the
Git Standard Library.

One important piece of feedback I received from the previous series is
that Git should be the first consumer of its own libraries. Objects in
git-std-lib.a are no longer contained in LIB_OBJS, but rather directly
built into git-std-lib.a and then linked into git.a. There is some
functionality that is used by git-std-lib.a that's not included in
git-std-lib.a, such as tracing support. These have been stubbed out into
git-stub-lib.a and can be built with git-std-lib.a to be used
externally. Thank you to Philip Wood for these suggestions[2]!

The test file and Makefile have been updated to include cleanups
suggested by Junio. Since git-std-lib.a is now a dependency of Git, the
test file has also been included as part of the test suite. The series
has been rebased onto a recent version of `next` and function calls that
have been added/changed since the last reroll have also been included
into the test file.

Finally, through our libification syncs, there have been various topics
and questions brought up that would be better clarified with additional
documentation in technical/git-std-lib.txt.
