0656781fad mv: update the path entry in .gitmodules for moved submodules
Currently using "git mv" on a submodule moves the submodule's work tree in
that of the superproject. But the submodule's path setting in .gitmodules
is left untouched, which is now inconsistent with the work tree and makes
git commands that rely on the proper path -> name mapping (like status and
diff) behave strangely.

Let "git mv" help here by not only moving the submodule's work tree but
also updating the "submodule.<submodule name>.path" setting from the
.gitmodules file and stage both. This doesn't happen when no .gitmodules
file is found and only issues a warning when it doesn't have a section for
this submodule. This is because the user might just use plain gitlinks
without the .gitmodules file or has already updated the path setting by
hand before issuing the "git mv" command (in which case the warning
reminds him that mv would have done that for him). Only when .gitmodules
is found and contains merge conflicts the mv command will fail and tell
the user to resolve the conflict before trying again.

Also extend the man page to inform the user about this new feature.

5fee995244 submodule.c: add .gitmodules staging helper functions
Add the new is_staging_gitmodules_ok() and stage_updated_gitmodules()
functions to submodule.c. The first makes it possible for call sites to
see if the .gitmodules file did contain any unstaged modifications they
would accidentally stage in addition to those they intend to stage
themselves. The second function stages all modifications to the
.gitmodules file, both will be used by subsequent patches for the mv
and rm commands.

a88c915de9 mv: move submodules using a gitfile
When moving a submodule which uses a gitfile to point to the git directory
stored in .git/modules/<name> of the superproject two changes must be made
to make the submodule work: the .git file and the core.worktree setting
must be adjusted to point from work tree to git directory and back.

Achieve that by remembering which submodule uses a gitfile by storing the
result of read_gitfile() of each submodule. If that is not NULL the new
function connect_work_tree_and_git_dir() is called after renaming the
submodule's work tree which updates the two settings to the new values.

Extend the man page to inform the user about that feature (and while at it
change the description to not talk about a script anymore, as mv is a
builtin for quite some time now).

1150246828 mv: move submodules together with their work trees
Currently the attempt to use "git mv" on a submodule errors out with:

  fatal: source directory is empty, source=<src>, destination=<dest>

The reason is that mv searches for the submodule with a trailing slash in
the index, which it doesn't find (because it is stored without a trailing
slash). As it doesn't find any index entries inside the submodule it
claims the directory would be empty even though it isn't.

Fix that by searching for the name without a trailing slash and continue
if it is a submodule. Then rename() will move the submodule work tree just
like it moves a file.

bd30c2e484 pathspec: support :(glob) syntax
:(glob)path differs from plain pathspec that it uses wildmatch with
WM_PATHNAME while the other uses fnmatch without FNM_PATHNAME. The
difference lies in how '*' (and '**') is processed.

With the introduction of :(glob) and :(literal) and their global
options --[no]glob-pathspecs, the user can:

 - make everything literal by default via --noglob-pathspecs
   --literal-pathspecs cannot be used for this purpose as it
   disables _all_ pathspec magic.

 - individually turn on globbing with :(glob)

 - make everything globbing by default via --glob-pathspecs

 - individually turn off globbing with :(literal)

The implication behind this is, there is no way to gain the default
matching behavior (i.e. fnmatch without FNM_PATHNAME). You either get
new globbing or literal. The old fnmatch behavior is considered
deprecated and discouraged to use.

233c3e6c59 parse_pathspec: preserve prefix length via PATHSPEC_PREFIX_ORIGIN
The prefix length is passed from one command to another via the new
magic 'prefix'. The magic is for parse_pathspec's internal use only,
not visible to parse_pathspec's callers.

Prefix length is not preserved across commands when --literal-pathspecs
is specified (no magic is allowed, including 'prefix'). That's OK
because we know all paths are literal. No magic, no special treatment
regarding prefix. (This may be no longer true if we make :(glob)
default)

Other options to preserve the prefix include saving it to env variable
or quoting. Env var way (at least _one_ env var) is not suitable
because the prefix is not the same for all pathspecs. Pathspecs
starting with "../" will eat into the prefix part.

We could also preserve 'prefix' across commands by quoting the prefix
part, then dequoting on receiving. But it may not be 100% accurate, we
may dequote longer than the original prefix part, for example. That
may be good or not, but it's not the purpose.

931eab64ad check-ignore: convert to use parse_pathspec
check-ignore (at least the test suite) seems to rely on the pattern
order. PATHSPEC_KEEP_ORDER is introduced to explictly express this.
The lack of PATHSPEC_MAXDEPTH_VALID is sufficient because it's the
only flag that reorders pathspecs, but it's less obvious that way.

dad2586a6b parse_pathspec: support prefixing original patterns
This makes 'original' suitable for passing to an external command
because all pathspec magic is left in place, provided that the
external command understands pathspec. The prefixing is needed because
we usually launch a subcommand at worktree's top directory and the
subcommand can no longer calculate the prefix itself.

This slightly affects the original purpose of 'original'
(i.e. reporting). We should report without prefixing. So only turn
this flag on when you know you are about to pass the result straight
away to an external command.

6330a17199 parse_pathspec: add special flag for max_depth feature
match_pathspec_depth() and tree_entry_interesting() check max_depth
field in order to support "git grep --max-depth". The feature
activation is tied to "recursive" field, which led to some unwanted
activation, e.g. 5c8eeb8 (diff-index: enable recursive pathspec
matching in unpack_trees - 2012-01-15).

This patch decouples the activation from "recursive" field, puts it in
"magic" field instead. This makes sure that only "git grep" can
activate this feature. And because parse_pathspec knows when the
feature is not used, it does not need to sort pathspec (required for
max_depth to work correctly). A small win for non-grep cases.

Even though a new magic flag is introduced, no magic syntax is. The
magic can be only enabled by parse_pathspec() caller. We might someday
want to support ":(maxdepth:10)src." It all depends on actual use
cases.

max_depth feature cannot be enabled via init_pathspec() anymore. But
that's ok because init_pathspec() is on its way to /dev/null.

87323bdace add parse_pathspec() that converts cmdline args to struct pathspec
Currently to fill a struct pathspec, we do:

   const char **paths;
   paths = get_pathspec(prefix, argv);
   ...
   init_pathspec(&pathspec, paths);

"paths" can only carry bare strings, which loses information from
command line arguments such as pathspec magic or the prefix part's
length for each argument.

parse_pathspec() is introduced to combine the two calls into one. The
plan is gradually replace all get_pathspec() and init_pathspec() with
parse_pathspec(). get_pathspec() now becomes a thin wrapper of
parse_pathspec().

parse_pathspec() allows the caller to reject the pathspec magics that
it does not support. When a new pathspec magic is introduced, we can
enable it per command after making sure that all underlying code has no
problem with the new magic.

"flags" parameter is currently unused. But it would allow callers to
pass certain instructions to parse_pathspec, for example forcing
literal pathspec when no magic is used.

With the introduction of parse_pathspec, there are now two functions
that can initialize struct pathspec: init_pathspec and
parse_pathspec. Any semantic changes in struct pathspec must be
reflected in both functions. init_pathspec() will be phased out in
favor of parse_pathspec().
