OPTION_INTEGER hardcodes its argh member to be "n", but the decision is
hidden deep in usage_with_options_internal(). Make "n" the default argh
for the OPT_INTEGER macro while leaving it undecided for the OPTION_INTEGER
enum.
This makes it less surprising to users that argh is "n" when using the
OPT_INTEGER macro.

Commit dbd0f5c (Files given on the command line are relative to $cwd,
2008-08-06) introduced parse_options_fix_filename() as a minimal fix.
OPT_FILENAME is intended to be a more robust fix for the same issue.
OPT_FILENAME and its associated enum OPTION_FILENAME are used to
represent filename options within the parse options API.
This option is similar to OPTION_STRING. If --no is prefixed to the
option the filename is unset. If no argument is given and the default
value is set, the filename is set to the default value. The difference
is that the filename is prefixed with the prefix passed to
parse_options() (or parse_options_start()).
Update git-apply, git-commit, git-fmt-merge-msg, and git-tag to use
OPT_FILENAME with their filename options. Also, rename
parse_options_fix_filename() to fix_filename() as it is no longer
extern.

To give OPT_FILENAME the prefix, we pass the prefix to parse_options()
which passes the prefix to parse_options_start() which sets the prefix
member of parse_opts_ctx accordingly. If there isn't a prefix in the
calling context, passing NULL will suffice.

This helps to notice when something's going wrong, especially on

I used the following criteria when selecting the code for replacement:
- it was already printing a warning for the unlink failures
- it is in a function which already printing something or is
called from such a function
- it is in a static function, returning void and the function is only
called from a builtin main function (cmd_)
- it is in a function which handles emergency exit (signal handlers)
- it is in a function which is obvously cleaning up the lockfiles

The user may put some effort into writing an annotated tag
message. When the tagging process later fails (which can
happen fairly easily, since it may be dependent on gpg being
correctly configured and used), there is no record left on
disk of the tag message.
Instead, let's keep the TAG_EDITMSG file around until we are
sure the tag has been created successfully. If we die
because of an error, the user can recover their text from
that file. Leaving the file in place causes no conflicts;
it will be silently overwritten by the next annotated tag
creation.
This matches the behavior of COMMIT_EDITMSG, which stays
around in case of error.

When running "git commit -F file" and "git tag -F file" from a
subdirectory, we should take it as relative to the directory we started
from, not relative to the top-level directory.
This adds a helper function "parse_options_fix_filename()" to make it more
convenient to fix this class of issues. Ideally, parse_options() should
support a new type of option, "OPT_FILENAME", to do this uniformly, but
this patch is meant to go to 'maint' to fix it minimally.
One thing to note is that value for "commit template file" that comes from
the command line is taken as relative to $cwd just like other parameters,
but when it comes from the configuration varilable 'commit.template', it
is taken as relative to the working tree root as before. I think this
difference actually is sensible (not that I particularly think
commit.template itself is sensible).

only on Windows but on all platforms to keep the code simpler.

By setting .in, .out, or .err members of struct child_process to -1, the
callers of start_command() can request that a pipe is allocated that talks
to the child process and one end is returned by replacing -1 with the
file descriptor.
Previously, a flag was set (for .in and .out, but not .err) to signal
finish_command() to close the pipe end that start_command() had handed out,
so it was optional for callers to close the pipe, and many already do so.
Now we make it mandatory to close the pipe.

Commit 3968658599 broke signed tags using
the "-u" flag when it made builtin-tag.c use parse_options() to parse its
arguments (but it quite possibly was broken even before that, by the
builtin rewrite).
It used to be that passing the signing ID with the -u parameter also
(obviously!) implied that you wanted to sign and annotate the tag, but
that logic got dropped. It also totally ignored the actual key ID that was
passed in.
This reinstates it all.

An earlier fix to the said commit was incomplete; it mixed up the
meaning of the flag parameter passed to the internal fmt_ident()
function, so this corrects it.
git_author_info() and git_committer_info() can be told to issue a
warning when no usable user information is found, and optionally can be
told to error out. Operations that actually use the information to
record a new commit or a tag will still error out, but the caller to
leave reflog record will just silently use bogus user information.
Not warning on misconfigured user information while writing a reflog
entry is somewhat debatable, but it is probably nicer to the users to
silently let it pass, because the only information you are losing is who
checked out the branch.
* git_author_info() and git_committer_info() used to take 1 (positive
int) to error out with a warning on misconfiguration; this is now
signalled with a symbolic constant IDENT_ERROR_ON_NO_NAME.
* These functions used to take -1 (negative int) to warn but continue;
this is now signalled with a symbolic constant IDENT_WARN_ON_NO_NAME.
* fmt_ident() function implements the above error reporting behaviour
common to git_author_info() and git_committer_info(). A symbolic
constant IDENT_NO_DATE can be or'ed in to the flag parameter to make
it return only the "Name <email@address.xz>".
* fmt_name() is a thin wrapper around fmt_ident() that always passes
IDENT_ERROR_ON_NO_NAME and IDENT_NO_DATE.
