Since 122aa6f9c0 (diff: introduce diff.<driver>.binary, 2008-10-05)
the internals of the userdiff.c code have understood a "default" name,
which is invoked as userdiff_find_by_name("default") and present in
the "builtin_drivers" struct. Let's test for this special case.

Refactor the userdiff_find_by_namelen() function so that a new
for_each_userdiff_driver() API function does most of the work.
This will be useful for the same reason we've got other for_each_*()
API functions as part of various APIs, and will be used in a follow-up
commit.

Address some old code smell and move around the built-in userdiff
drivers so they're both in alphabetical order, and now in the same
order they appear in the gitattributes(5) documentation.
The two started drifting in be58e70dba (diff: unify external diff and
funcname parsing code, 2008-10-05), and then even further in
80c49c3de2 (color-words: make regex configurable via attributes,
2009-01-17) when the "cpp" pattern was added.
There are no functional changes here, and as --color-moved will show
only moved existing lines.

In 56c6910028 (fsmonitor: change last update timestamp on the
index_state to opaque token, 2020-01-07), we forgot to adjust the part
of `unpack_trees()` that copies the FSMonitor "last-update" information
that we copy from the source index to the result index since 679f2f9fdd
(unpack-trees: skip stat on fsmonitor-valid files, 2019-11-20).
Since the "last-update" information is no longer a 64-bit number, but a
free-form string that has been allocated, we need to duplicate it rather
than just copying it.
This is important because there _are_ cases when `unpack_trees()` will
perform a oneway merge that implicitly calls `refresh_fsmonitor()`
(which will allocate that "last-update" token). This happens _after_
that token was copied into the result index. However, we _then_ call
`check_updates()` on that index, which will _also_ call
`refresh_fsmonitor()`, accessing the "last-update" string, which by now
would be released already.
In the instance that lead to this patch, this caused a segmentation
fault during a lengthy, complicated rebase involving the todo command
`reset` that (crucially) had to updated many files. Unfortunately, it
seems very hard to trigger that crash, therefore this patch is not
accompanied by a regression test.

This patch fixes a bug where git-bisect doesn't handle receiving
annotated tags as "git bisect good <tag>", etc. It's a regression in
27257bc466 (bisect--helper: reimplement `bisect_state` & `bisect_head`
shell functions in C, 2020-10-15).
The original shell code called:
sha=$(git rev-parse --verify "$rev^{commit}") ||
die "$(eval_gettext "Bad rev input: \$rev")"
which will peel the input to a commit (or complain if that's not
possible). But the C code just calls get_oid(), which will yield the oid
of the tag.
The fix is to peel to a commit. The error message here is a little
non-idiomatic for Git (since it starts with a capital). I've mostly left
it, as it matches the other converted messages (like the "Bad rev input"
we print when get_oid() fails), though I did add an indication that it
was the peeling that was the problem. It might be worth taking a pass
through this converted code to modernize some of the error messages.
Note also that the test does a bare "grep" (not i18ngrep) on the
expected "X is the first bad commit" output message. This matches the
rest of the test script.

4f37d45706 ("clone: respect remote unborn HEAD", 2021-02-05) introduces
a new feature (if the remote has an unborn HEAD, e.g. when the remote
repository is empty, use it as the name of the branch) that only works
in protocol v2, but did not ensure that one of its tests always uses
protocol v2, and thus that test would fail if
GIT_TEST_PROTOCOL_VERSION=0 (or 1) is used. Therefore, add "-c
protocol.version=2" to the appropriate test.
(The rest of the tests from that commit have "-c protocol.version=2"
already added.)

Allow BLOCK_GROWTH_SIZE to be used like an integer literal by removing
the trailing semicolon from its definition. Also wrap the expression in
parentheses, to allow it to be used with operators without leading to
unexpected results. It doesn't matter for the current use site, but
make it follow standard macro rules anyway to avoid future surprises.

23119ffb4e (block-sha1: put expanded macro parameters in parentheses,
2012-07-22) added a trailing semicolon to the definition of SHA_MIX
without explanation. It doesn't matter with the current code, but make
sure to avoid potential surprises by removing it again.
This allows the macro to be used almost like a function: Users can
combine it with operators of their choice, but still must not pass an
expression with side-effects as a parameter, as it would be evaluated
multiple times.
