Use __FBSDID().

Import the libc fnmatch() into the kernel. This will be used by,
among other things, the DEVFS rule subsystem to match nodes against a
path pattern supplied by the user.

fnmatch.c was repo-copied from src/lib/libc/gen/fnmatch.c, and the
only changes to it are those necessary to make it compile in the
kernel. The relevant parts of fnmatch.h were imported into libkern.h.

* Remove __P and convert to ANSI prototypes.
* Remove 'register'. (some functions had 7+ register functions...)
* Fix SCM ID's.

Style optimization in newly added POSIX range []] conformance, redo
'for' loop as do...while and remove variable unneded now

Add missing FNM_PERIOD check for '[' range
Don't treat !^ as first characters in the range, just as negate sign
[/] never match if FNM_PATHNAME

1) Now conforms POSIX.2 2.8.3.2 requirements about []] pattern
2) Treat unclosed [ range in pattern as regular characters (bash style)

Fix a bug that caused some false mismatches when both FNM_PATHNAME
and FNM_LEADING_DIR were specified and the pattern ended with "*".
Example: pattern="src/usr.sbin/w*", string="src/usr.sbin/watch/watch.8,v".
This should match, but did not.

Eliminate some function calls when locale not used

Speedup in case locale not used

2) Add FNM_LEADING_DIR
Add proper (unsigned char) casts to tolower().
Use 'char' function argument for proper sign extension

add flag FNM_ICASE for case insensitve search
