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. Approved by: -arch
