The "verify_pathspec()" function doesn't test for ending NUL character in
the pathspec, causing some really funky and unexpected behaviour. It just
happened to work in the cases I had tested.

This generalizes the git "glob" string to be a lot more like the
git-diff-* pathspecs (but there are still differences: the diff family
doesn't do any globbing, and because the diff family always generates the
full native pathname, it doesn't have the issue with "..").
It does three things:
- it allows multiple matching strings, ie you can do things like
git-ls-files arch/i386/ include/asm-i386/ | xargs grep pattern
- the "matching" criteria is a combination of "exact path component
match" (the same as the git-diff-* family), and "fnmatch()". However,
you should be careful with the confusion between the git-ls-files
internal globbing and the standard shell globbing, ie
git-ls-files fs/*.c
does globbing in the shell, and does something totally different from
git-ls-files 'fs/*.c'
which does the globbing inside git-ls-files.
The latter has _one_ pathspec with a wildcard, and will match any .c
file anywhere under the fs/ directory, while the former has been
expanded by the shell into having _lots_ of pathspec entries, all of
which are just in the top-level fs/ subdirectory. They will happily
be matched exactly, but we will thus miss all the subdirectories under
fs/.
As a result, the first one will (on the current kernel) match 55 files,
while the second one will match 664 files!
- it uses the generic path prefixing, so that ".." and friends at the
beginning of the path spec work automatically
NOTE! When generating relative pathname output (the default), a
pathspec that causes the base to be outside the current working
directory will be rejected with an error message like:
fatal: git-ls-files: cannot generate relative filenames containing '..'
because we do not actually generate ".." in the output. However, the
".." format works fine for the --full-name case:
cd arch/i386/kernel
git-ls-files --full-name ../mm/
results in
arch/i386/mm/Makefile
arch/i386/mm/boot_ioremap.c
arch/i386/mm/discontig.c
arch/i386/mm/extable.c
arch/i386/mm/fault.c
arch/i386/mm/highmem.c
arch/i386/mm/hugetlbpage.c
arch/i386/mm/init.c
arch/i386/mm/ioremap.c
arch/i386/mm/mmap.c
arch/i386/mm/pageattr.c
arch/i386/mm/pgtable.c
Perhaps more commonly, the generic path prefixing means that "." and
"./" automatically get simplified and work properly.

This makes git-ls-files work inside a relative directory, and also adds
some rudimentary filename globbing support. For example, in the kernel you
can now do
cd arch/i386
git-ls-files
and it will show all files under that subdirectory (and it will have
removed the "arch/i386/" prefix unless you give it the "--full-name"
option, so that you can feed the result to "xargs grep" or similar).
The filename globbing is kind of strange: it does _not_ follow normal
globbing rules, although it does look "almost" like a normal file glob
(and it uses the POSIX.2 "fnmatch()" function).
The glob pattern (there can be only one) is always split into a "directory
part" and a "glob part", where the directory part is defined as any full
directory path without any '*' or '?' characters. The "glob" part is
whatever is left over.
For example, when doing
git-ls-files 'arch/i386/p*/*.c'
the "directory part" is is "arch/i386/", and the "glob part" is "p*/*.c".
The directory part will be added to the prefix, and handled efficiently
(ie we will not be searching outside of that subdirectory), while the glob
part (if anything is left over) will be used to trigger "fnmatch()"
matches.
This is efficient and very useful, but can result in somewhat
non-intuitive behaviour.
For example:
git-ls-files 'arch/i386/*.[ch]'
will find all .c and .h files under arch/i386/, _including_ things in
lower subdirectories (ie it will match "arch/i386/kernel/process.c",
because "kernel/process.c" will match the "*.c" specifier).
Also, while
git-ls-files arch/i386/
will show all files under that subdirectory, doing the same without the
final slash would try to show the file "i386" under the "arch/"
subdirectory, and since there is no such file (even if there is such a
_directory_) it will not match anything at all.
These semantics may not seem intuitive, but they are actually very
practical. In particular, it makes it very simple to do
git-ls-files fs/*.c | xargs grep some_pattern
and it does what you want.

Pasky and others raised many valid points on the problems
initial exclude pattern enhancement work had. Based on the
list discussion, rework the exclude logic to use "last match
determines its fate" rule, and order the list by exclude-from
(the fallback default pattern file), exclude-per-directory
(shallower to deeper, so deeper ones can override), and then
command line exclude patterns.

Add --exclude-per-directory=<name> option that specifies a file
to contain exclude patterns local to that directory and its
subdirectories. Update the exclusion logic to be able to say
"include files that match this more specific pattern, even
though later exclude patterns may match them". Also enhances
that a pattern can contain '/' in which case fnmatch is called
with FNM_PATHNAME flag to match the entire path.

Fix various things that sparse complains about:
- use NULL instead of 0
- make sure we declare everything properly, or mark it static
- use proper function declarations ("fn(void)" instead of "fn()")
Sparse is always right.

When checkout-cache attempts to check out a non-directory where
a directory exists on the work tree, or to check out a file
under directory D when path D is a non-directory on the work
tree, the attempt fails. Before running checkout-cache, the
user can run git-ls-files with the -k (killed) option to get a
list of such paths. The tagged output format uses "K" to denote
them. This is useful for Porcelain layer to be careful when
dealing with the recently corrected behaviour of checkout-cache.

It is kind of surprising that this was missed in the last round,
but the work tree scanner in git-ls-files was still deliberately
ignoring symlinks. This patch fixes it, so that --others will
correctly report unregistered symlinks.

Allow to store and track symlink in the repository. A symlink is stored
the same way as a regular file, only with the appropriate mode bits set.
The symlink target is therefore stored in a blob object.
This will hopefully make our udev repository fully functional. :)
