make use of new glob(3) GLOB_KEEPSTAT extension to save extra server
rountrips to fetch per-file stat(2) information.
NB. update openbsd-compat/ glob(3) implementation from OpenBSD libc to
match.
test for GLOB_NOMATCH and use our glob functions if it's not found.
Stops sftp from segfaulting when attempting to get a nonexistent file on
Cygwin (previous versions of OpenSSH didn't use the native glob). Partly
from and tested by Corinna Vinschen.

make the portable tree compile again - sprinkle unistd.h and string.h
back in. Don't redefine __unused, as it turned out to be used in
headers on Linux, and replace its use in auth-pam.c with ARGSUSED
missing or lacks the GLOB_ALTDIRFUNC extension
- (djm) Remove -I$(srcdir)/openbsd-compat from CFLAGS, refer to headers
relatively. Avoids conflict between glob.h and /usr/include/glob.h
