apply: use strcmp(3) for comparing strings in gitdiff_verify_name()
We don't know the length of the C string "another". It could be
shorter than "name", which we compare it to using memchr(3). Call
strcmp(3) instead to avoid running over the end of the former, and
get rid of a strlen(3) call as a bonus.

Avoid running over the end of line -- a C string whose length is not
known to this function -- by using starts_with() instead of memcmp(3)
for checking if it starts with "/dev/null". Also simply include the
newline in the string constant to compare against. Drop a comment that
just states the obvious.

apply: move libified code from builtin/apply.c to apply.{c,h}
As most of the apply code in builtin/apply.c has been libified by a number of

The constants for the "inaccurate-eof" and the "recount" options will
be used in both "apply.c" and "builtin/apply.c", so they need to go
into "apply.h", and therefore they need a name that is more specific

gives the same exit code as when die() or exit(1) is called. This way
scripts relying on the exit code don't need to be changed.
While doing that we must take care that file descriptors are properly closed
and, if needed, reset to a sensible value.
Also, according to the lockfile API, when finished with a lockfile, one
should either commit it or roll it back.
This is even more important now that the same lockfile can be passed
to init_apply_state() many times to be reused by series of calls to
the apply lib functions.

When the GPG prereq is not set, we do not run test 34. That
test changes the directory of the test script as a side
effect (something we usually frown on, but which matches the
style of the rest of this script). When test 35 (the
url-scrubbing test) runs, it expects to be in the directory
from test 34. If it's not, the test fails; we are in a
different sub-repo, our test-commit is built on a different
history, and the push becomes a non-fast-forward.
We can fix this by unconditionally moving to the directory
we expect (again, against our usual style but matching how
the rest of the script operates).
As an additional protection, let's also switch from "make a
new commit and push to master" to just "push to a new
branch". We don't care about the branch name; we just want
_some_ ref update to trigger the status output. Pushing to a
new branch is less likely to run into problems with
force-updates, changing the checked-out branch, etc.

grep.c: reuse "icase" variable
diffcore-pickaxe: support case insensitive match on non-ascii
diffcore-pickaxe: Add regcomp_or_die()
grep/pcre: support utf-8
gettext: add is_utf8_locale()
grep/pcre: prepare locale-dependent tables for icase matching
grep: rewrite an if/else condition to avoid duplicate expression
grep/icase: avoid kwsset when -F is specified
grep/icase: avoid kwsset on literal non-ascii strings
test-regex: expose full regcomp() to the command line
test-regex: isolate the bug test code
grep: break down an "if" stmt in preparation for next changes
The commands in the "log/diff" family have had an FILE* pointer in the
data structure they pass around for a long time, but some codepaths
used to always write to the standard output. As a preparatory step
to make "git format-patch" available to the internal callers, these
codepaths have been updated to consistently write into that FILE*
instead.
* js/log-to-diffopt-file:
mingw: fix the shortlog --output=<file> test
diff: do not color output when --color=auto and --output=<file> is given
t4211: ensure that log respects --output=<file>
shortlog: respect the --output=<file> setting
format-patch: use stdout directly
format-patch: avoid freopen()
format-patch: explicitly switch off color when writing to files
shortlog: support outputting to streams other than stdout
graph: respect the diffopt.file setting
line-log: respect diffopt's configured output file stream
log-tree: respect diffopt's configured output file stream
log: prepare log/log-tree to reuse the diffopt.close_file attribute
Fix recently introduced codepaths that are involved in parallel
submodule operations, which gave up on reading too early, and
could have wasted CPU while attempting to write under a corner
case condition.
* sb/submodule-parallel-fetch:
hoist out handle_nonblock function for xread and xwrite
xwrite: poll on non-blocking FDs
xread: retry after poll on EAGAIN/EWOULDBLOCK
