For now it's unable to stop at unknown options, this commit merely
reorganize some code around.

There are quite a few places that will need to call approxidate(),
when they'll adopt the parse-options system, so this patch adds the
function parse_opt_approxidate_cb(), used by OPT_DATE.

* js/remote:
"remote update": print remote name being fetched from
builtin remote rm: remove symbolic refs, too
remote: fix "update [group...]"
remote show: Clean up connection correctly if object fetch wasn't done
builtin-remote: prune remotes correctly that were added with --mirror
Make git-remote a builtin
Test "git remote show" and "git remote prune"
parseopt: add flag to stop on first non option
path-list: add functions to work with unsorted lists
Conflicts:
parse-options.c
This is meant to be used to keep --not and --all during revision parsing.

This is useful for backward-compatibility aliases, or very advanced command
line switches introduced for internal git usages and have no real use for a
user.
parse-options still shows them if the user asks for --help-all.

options flags:
~~~~~~~~~~~~~
PARSE_OPT_NONEG allow the caller to disallow the negated option to exists.
option types:
~~~~~~~~~~~~
OPTION_BIT: ORs (or NANDs) a mask.
OPTION_SET_INT: force the value to be set to this integer.
OPTION_SET_PTR: force the value to be set to this pointer.
helper:
~~~~~~
HAS_MULTI_BITS (in git-compat-util.h) is a bit-hack to check if an
unsigned integer has more than one bit set, useful to check if conflicting
options have been used.

* 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
