Create a function that, taking a string, describes the position of its
trailer block (if available) and the contents thereof, and make trailer
use it. This makes it easier for other Git components, in the future, to
interpret trailer blocks in the same way as trailer.
In a subsequent patch, another component will be made to use this.

trailer.c currently splits lines while processing a buffer (and also
rejoins lines when needing to invoke ignore_non_trailer).
Avoid such line splitting, except when generating the strings
corresponding to trailers (for ease of use by clients - a subsequent
patch will allow other components to obtain the layout of a trailer
block in a buffer, including the trailers themselves). The main purpose
of this is to make it easy to return pointers into the original buffer
(for a subsequent patch), but this also significantly reduces the number
of memory allocations required.

Currently, a line is interpreted to be a trailer line if it contains a
separator. Make parsing stricter by requiring the text on the left of

Since 650c44925 (common-main: call git_extract_argv0_path(),
2016-07-01), the argv[0] that is seen in cmd_main() of
individual programs is always the basename of the
executable, as common-main strips off the full path. This
can produce confusing results for git-daemon, which wants to
re-exec itself.
For instance, if the program was originally run as
"/usr/lib/git/git-daemon", it will try just re-execing
"git-daemon", which will find the first instance in $PATH.
If git's exec-path has not been prepended to $PATH, we may
find the git-daemon from a different version (or no
git-daemon at all).
Normally this isn't a problem. Git commands are run as "git
daemon", the git wrapper puts the exec-path at the front of
$PATH, and argv[0] is already "daemon" anyway. But running
git-daemon via its full exec-path, while not really a
recommended method, did work prior to 650c44925. Let's make
it work again.
The real goal of 650c44925 was not to munge argv[0], but to
reliably set the argv0_path global. The only reason it
munges at all is that one caller, the git.c wrapper,
piggy-backed on that computation to find the command
basename. Instead, let's leave argv[0] untouched in
common-main, and have git.c do its own basename computation.
While we're at it, let's drop the return value from
git_extract_argv0_path(). It was only ever used in this one
callsite, and its dual purposes is what led to this
confusion in the first place.
Note that by changing the interface, the compiler can
confirm for us that there are no other callers storing the
return value. But the compiler can't tell us whether any of
the cmd_main() functions (besides git.c) were relying on the
basename munging. However, we can observe that prior to
650c44925, no other cmd_main() functions did that munging,
and no new cmd_main() functions have been introduced since
then. So we can't be regressing any of those cases.

The lazy prereq for MKTEMP uses "mktemp -t" to see if
mergetool's internal mktemp call will be able to run. But
unlike the call inside mergetool, we do not ever bother to
clean up the result, and the /tmp of git developers will
slowly fill up with "foo.XXXXXX" directories as they run the
test suite over and over. Let's clean up the directory
after we've verified its creation.
Note that we don't use test_when_finished here, and instead
just make rmdir part of the &&-chain. We should only remove
something that we're confident we just created. A failure in
the middle of the chain either means there's nothing to
clean up, or we are very confused and should err on the side
of caution.

Allow vimdiff users to signal that they do not want to use the
result of a merge by exiting with ":cquit", which tells Vim to
exit with an error code.
This is better than the current behavior because it allows users
to directly flag that the merge is bad, using a standard Vim
feature, rather than relying on a timestamp heuristic that is
unforgiving to users that save in-progress merge files.
The original behavior can be restored by configuring
mergetool.vimdiff.trustExitCode to false.

Built-in merge tools contain a hard-coded assumption about
whether or not a tool's exit code can be trusted to determine
the success or failure of a merge. Tools whose exit codes are
not trusted contain calls to check_unchanged() in their
merge_cmd() functions.
A problem with this is that the trustExitCode configuration is
not honored for built-in tools.
Teach built-in tools to honor the trustExitCode configuration.
Extend run_merge_cmd() so that it is responsible for calling
check_unchanged() when a tool's exit code cannot be trusted.
Remove check_unchanged() calls from scriptlets since they are no
longer responsible for calling it.
When no configuration is present, exit_code_trustable() is
checked to see whether the exit code should be trusted.
The default implementation returns false.
Tools whose exit codes can be trusted override
exit_code_trustable() to true.

Merge-recursive sorts a string list using a raw qsort(), where it
feeds the "items" from one struct but the "nr" and size fields from
another struct. This isn't a bug because one list is a copy of the
other, but it's unnecessarily confusing (and also caused our recent
QSORT() cleanups via coccinelle to miss this call site).
Let's use string_list_sort() instead, which is more concise and harder
to get wrong. Note that we need to adjust our comparison function,
which gets fed only the strings now, not the string_list_items. That's
OK because we don't use the "util" field as part of our sort.

This is required by git-worktree.txt, stating that the main worktree is
the first line (especially in --porcelain mode when we can't just change
behavior at will).
There's only one case when get_worktrees() may skip main worktree, when
parse_ref() fails. Update the code so that we keep first item as main
worktree and return something sensible in this case:
- In user-friendly mode, since we're not constraint by anything,
returning "(error)" should do the job (we already show "(detached
HEAD)" which is not machine-friendly). Actually errors should be
printed on stderr by parse_ref() (*)
- In plumbing mode, we do not show neither 'bare', 'detached' or
'branch ...', which is possible by the format description if I read
it right.
Careful readers may realize that when the local variable "head_ref" in
get_main_worktree() is emptied, add_head_info() will do nothing to
wt->head_sha1. But that's ok because head_sha1 is zero-ized in the
previous patch.
(*) Well, it does not. But it's supposed to be a stop gap implementation
until we can reuse refs code to parse "ref: " stuff in HEAD, from
resolve_refs_unsafe(). Now may be the time since refs refactoring is
mostly done.

`NULL` not being handled properly.
