src/usr.bin/modstat, branch upstream/2.1.7

Fix an exploitable buffer overflow condition. From l0pht:

Modstat is sgid kmem which is really handy to become if you feel like looking through /dev/mem and /dev/kmem (gee, wonder what you might want to do that for ). Like just about everything else under the sun it has a buffer overflow problem. The problem exists in the dostat() routine where an arbitrary sized string is shoved into sbuf.name through a strcpy(). This change was committed to 2.2 as rev. 1.4 of modstat.c by joerg, and is being duplicated verbatim in 2.1-STABLE -JG

This 3rd mega-commit should hopefully bring us back to where we were.

some (hopefully) less offensive stupidity: If we detect that a user has loaded a module that fails to initialize itself correctly, panic. There really isn't a safe way to recover from something like this; we can't know that the module is bad until after the entry point is called, by which time it's too late to do anything about it.

Small fixups to use LM_UNKNOWN type, also fix slight formatting
