The i18n config variable used weren't readable as they were in
the crude form of how git stores/uses it's config variables.
Improve it's readability by replacing them with camelCased versions
of config variables as it doesn't have any impact on it's usage.

The test_copy_bytes() function claims to read up to N bytes,
or until it gets EOF. But we never handle EOF in our loop,
and a short input will cause perl to go into an infinite
loop of read() getting zero bytes.

FD_CLOEXEC only applies to the file descriptor, so it needs to be
manipuluated via F_GETFD/F_SETFD. F_GETFL/F_SETFL are for file
description flags.

We set old_oid to NULL if we found out that it's a corrupt reference.
In that case don't try to access the hash member and pass NULL to
ref_transaction_delete() instead.

It is totally legitimate to add CamelCased aliases, but due to the way
config keys are compared, the case does not matter.
Therefore, we must compare the alias name insensitively to the config
keys.
This fixes a regression introduced by a9bcf6586d (alias: use
the early config machinery to expand aliases, 2017-06-14).

The build procedure has been improved to allow building and testing
Git with address sanitizer more easily.
* jk/build-with-asan:
Makefile: disable unaligned loads with UBSan
Makefile: turn off -fomit-frame-pointer with sanitizers
Makefile: add helper for compiling with -fsanitize
test-lib: turn on ASan abort_on_error by default
test-lib: set ASAN_OPTIONS variable before we run git
"git pull --rebase --recurse-submodules" learns to rebase the
branch in the submodules to an updated base.
* sb/pull-rebase-submodule:
builtin/fetch cleanup: always set default value for submodule recursing
pull: optionally rebase submodules (remote submodule changes only)
builtin/fetch: parse recurse-submodules-default at default options parsing
builtin/fetch: factor submodule recurse parsing out to submodule config
Update the hashmap API so that data to customize the behaviour of
the comparison function can be specified at the time a hashmap is
initialized.
* sb/hashmap-customize-comparison:
hashmap: migrate documentation from Documentation/technical into header
patch-ids.c: use hashmap correctly
hashmap.h: compare function has access to a data field
Code cleanup.
* ab/grep-lose-opt-regflags:
grep: remove redundant REG_NEWLINE when compiling fixed regex
grep: remove regflags from the public grep_opt API
grep: remove redundant and verbose re-assignments to 0
grep: remove redundant "fixed" field re-assignment to 0
grep: adjust a redundant grep pattern type assignment
grep: remove redundant double assignment to 0

The option -G of p4 (python marshal output) gives more context about the
data being output. That's useful when using the command "change -o" as
we can distinguish between warning/error line and real change description.
This fixes the case where a p4 trigger for "p4 change" is set and the command git-p4 submit is run.

Some p4 triggers in the server side generate some warnings when
executed. Unfortunately those messages are mixed with the output of
p4 commands. A few git-p4 commands don't expect extra messages or output
lines and may fail with verbose triggers.

We normally try to avoid having two auto-gc operations run
at the same time, because it wastes resources. This was done
long ago in 64a99eb47 (gc: reject if another gc is running,
unless --force is given, 2013-08-08).
When we do a detached auto-gc, we run the ref-related
commands _before_ detaching, to avoid confusing lock
contention. This was done by 62aad1849 (gc --auto: do not
lock refs in the background, 2014-05-25).
These two features do not interact well. The pre-detach
operations are run before we check the gc.pid lock, meaning
that on a busy repository we may run many of them
concurrently. Ideally we'd take the lock before spawning any
operations, and hold it for the duration of the program.
This is tricky, though, with the way the pid-file interacts
with the daemonize() process. Other processes will check
that the pid recorded in the pid-file still exists. But
detaching causes us to fork and continue running under a
new pid. So if we take the lock before detaching, the
pid-file will have a bogus pid in it. We'd have to go back
and update it with the new pid after detaching. We'd also
have to play some tricks with the tempfile subsystem to
tweak the "owner" field, so that the parent process does not
clean it up on exit, but the child process does.
Instead, we can do something a bit simpler: take the lock
only for the duration of the pre-detach work, then detach,
then take it again for the post-detach work. Technically,
this means that the post-detach lock could lose to another
process doing pre-detach work. But in the long run this
works out.
That second process would then follow-up by doing
post-detach work. Unless it was in turn blocked by a third
process doing pre-detach work, and so on. This could in
theory go on indefinitely, as the pre-detach work does not
repack, and so need_to_gc() will continue to trigger. But
in each round we are racing between the pre- and post-detach
locks. Eventually, one of the post-detach locks will win the
race and complete the full gc. So in the worst case, we may
racily repeat the pre-detach work, but we would never do so
simultaneously (it would happen via a sequence of serialized
race-wins).
