Simplify collection commits in a callback function by passing it a
commit_stack pointer all the way from the caller, instead of using
separate variables for array and item count and a bunch of intermediate
members in struct bitmap_commit_cb.

Calling commit_stack_push() to add commits is simpler and more efficient
than using REALLOC_ARRAY. Calling commit_stack_pop() to consume them in
LIFO order is also a tad simpler than calculating the array index from
the end.

Dynamic arrays of commit pointers are used in several places. Some of
them use a custom struct to hold array, item count and capacity, others
have them as separate variables linked by a common name part.
Pick one succinct, clean implementation -- commit_stack -- and convert
the different variants to it to reduce code duplication.

Copy detection cannot work when comparing the index to the working tree
because Git ignores files that it is not explicitly told to track. It
should work in the other direction, though, i.e. for a reverse diff of
the deletion of a copy from the index.
d1f2d7e8ca (Make run_diff_index() use unpack_trees(), not read_tree(),
2008-01-19) broke it with a seemingly stray change to run_diff_files().
We didn't notice because there's no test for that. But even if we had
one, it might have gone unnoticed because the breakage only happens
with index preloading, which requires at least 1000 entries (more than
most test repos have) and is racy because it runs in parallel with the
actual command.
Fix copy detection by queuing up-to-date and skip-worktree entries using
diff_same().
While at it, use diff_same() also for queuing unchanged files not
flagged as up-to-date, i.e. clean submodules and entries where
preloading was not done at all or not quickly enough. It uses less
memory than diff_change() and doesn't unnecessarily set the diff flag
has_changes.
Add two tests to cover running both without and with preloading. The
first one passes reliably with the original code. The second one
enables preloading and thus is racy. It has a good chance to pass even
without the fix, but fails within seconds when running the test script
with --stress. With the fix it runs fine for several minutes, until
my patience runs out.

There is no documentation for `--contained`.
Start by copying the text from `replay_options` in `builtin/
replay.c`. But some people think that the existing text is a
bit unclear; what does it mean for a branch to be contained
in a revision range? Let’s include the implied commits here:
the branches that point at commits in the range.
Also use “update” instead of “advance”. “Update” is the verb
commonly used in this context.
