This function can be used instead of "usage_with_options" when you
want to print an error message before the usage string.
It may be useful because:
if (condition)
usage_msg_opt("condition is false", usage, opts);
is shorter than:
if (condition) {
fprintf(stderr, "condition is false\n\n");
usage_with_options(usage, opts);
}
and may be more consistent.

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.

show-branch: migrate to parse-options API
parse-options: add PARSE_OPT_LITERAL_ARGHELP for complicated argh's
Conflicts:
parse-options.h
Usually, the argh element in struct option points at a placeholder value
(e.g. "val"), and is shown in the usage message as
--option=<val>
by enclosing the string inside of angle brackets.
When the option is more complex (e.g. optional arguments separated by a
comma), you would want to produce a usage message that looks like
--option=<val1>[,<val2>]
In such a case, the caller can pass a string to argh with placeholders
already enclosed in necessary angle brackets (e.g. "<val1>[,<val2>]")
and set this flag.

As suggested by Junio, disallow the flags PARSE_OPT_KEEP_UNKNOWN and
PARSE_OPT_STOP_AT_NON_OPTION to be turned on at the same time, as a
value of an unknown option could be mistakenly classified as a
non-option, stopping the parser early. E.g.:
git cmd --known --unknown value arg0 arg1
The parser should have stopped at "arg0", but it already stops at
"value".
This patch makes parse_options() die if the two flags are used in
combination.

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).

If options are aggregated, and that the whole token is an exact
prefix of a long option that is longer than 2 letters, reject
it. This is to prevent a common typo:
$ git commit -amend
to get interpreted as "commit all with message 'end'".
The typo check isn't performed if there is no aggregation,
because the stuck form is the recommended one. If we have `-o`
being a valid short option that takes an argument, and --option
a long one, then we _MUST_ accept -option as "'o' option with
argument 'ption'", which is our official recommended form.

* add the possibility to use callbacks to parse some options, this can
help implementing new options kinds with great flexibility. struct option
gains a callback pointer and a `defval' where callbacks user can put
either integers or pointers. callbacks also can use the `value' pointer
for anything, preferably to the pointer to the final storage for the value
though.
* add a `flag' member to struct option to make explicit that this option may
have an optional argument. The semantics depends on the option type. For
INTEGERS, it means that if the switch is not used in its
--long-form=<value> form, and that there is no token after it or that the
token does not starts with a digit, then it's assumed that the switch has
no argument. For STRING or CALLBACK it works the same, except that the
condition is that the next atom starts with a dash. This is needed to
implement backward compatible behaviour with existing ways to parse the
command line. Its use for new options is discouraged.

The option parser takes argc, argv, an array of struct option
and a usage string. Each of the struct option elements in the array
describes a valid option, its type and a pointer to the location where the
value is written. The entry point is parse_options(), which scans through
the given argv, and matches each option there against the list of valid
options. During the scan, argv is rewritten to only contain the
non-option command line arguments and the number of these is returned.
Aggregation of single switches is allowed:
-rC0 is the same as -r -C 0 (supposing that -C wants an arg).
Every long option automatically support the option with the same name,
prefixed with 'no-' to unset the switch. It assumes that initial value for
strings are "NULL" and for integers is "0".
Long options are supported either with '=' or without:
--some-option=foo is the same as --some-option foo
