Since v1.8.4 (about six months ago) wildmatch is used as default
replacement for fnmatch. We have seen only one fix since so wildmatch
probably has done a good job as fnmatch replacement. This concludes
the fnmatch->wildmatch transition by no longer relying on fnmatch.

This reverts commit 1b25892636d2f250eb2163301440ee8c8c1ac944. compat
fnmatch will be removed soon and we can't rely on fnmatch() available
everywhere.

This is similar to NO_FNMATCH but it uses wildmatch instead of
compat/fnmatch. This is an intermediate step to let wildmatch be used
as fnmatch replacement for wider audience before it replaces fnmatch
completely and compat/fnmatch is removed.
fnmatch in test-wildmatch is not impacted by this and is the only
place that NO_FNMATCH or NO_FNMATCH_CASEFOLD remain active when
USE_WILDMATCH is set.

It takes a text file, a pattern, a number <n> and pathname flag. Each
line in the text file is matched against the pattern <n> times. If
"pathname" is given, FNM_PATHNAME is used.
test-wildmatch is built with -O2 and tested against glibc 2.14.1 (also
-O2) and compat/fnmatch. The input file is linux-2.6.git file list.
<n> is 2000. The complete command list is at the end.
wildmatch is beaten in the following cases. Apparently it needs some
improvement in FNM_PATHNAME case:
glibc, '*/*/*' with FNM_PATHNAME:
wildmatch 8s 1559us
fnmatch 1s 11877us or 12.65% faster
compat, '*/*/*' with FNM_PATHNAME:
wildmatch 7s 922458us
fnmatch 2s 905111us or 36.67% faster
compat, '*/*/*' without FNM_PATHNAME:
wildmatch 7s 264201us
fnmatch 2s 1897us or 27.56% faster
compat, '[a-z]*/[a-z]*/[a-z]*' with FNM_PATHNAME:
wildmatch 8s 742827us
fnmatch 0s 922943us or 10.56% faster
compat, '[a-z]*/[a-z]*/[a-z]*' without FNM_PATHNAME:
wildmatch 8s 284520us
fnmatch 0s 6936us or 0.08% faster

So far, wildmatch() has always honoured directory boundary and there
was no way to turn it off. Make it behave more like fnmatch() by
requiring all callers that want the FNM_PATHNAME behaviour to pass
that in the equivalent flag WM_PATHNAME. Callers that do not specify
WM_PATHNAME will get wildcards like ? and * in their patterns matched
against '/', just like not passing FNM_PATHNAME to fnmatch().

- All exported constants now have a prefix WM_
- Do not rely on FNM_* constants, use the WM_ counterparts
- Remove TRUE and FALSE to follow Git's coding style
- While at it, turn flags type from int to unsigned int
- Add an (unused yet) argument to carry extra information
so that we don't have to change the prototype again later
when we need to pass other stuff to wildmatch

The MSYS bash mangles arguments that begin with a forward slash
when they are passed to test-wildmatch. This causes tests to fail.
Avoid mangling by prepending "XXX", which is removed by
test-wildmatch before further processing.

One place less to worry about thread safety. Also combine wildmatch
and iwildmatch into one.

wildmatch returns non-zero if matched, zero otherwise. This patch
makes it return zero if matches, non-zero otherwise, like fnmatch().
