[glob.c]
fix GLOB_KEEPSTAT without GLOB_NOSORT; the implicit sort was being
applied only to the gl_pathv vector and not the corresponding gl_statv
array. reported in OpenSSH bz#1935; feedback and okay matthew@
[openbsd-compat/glob.c]
When the max number of items for a directory has reached GLOB_LIMIT_READDIR
an error is returned but closedir() is not called.
spotted and fix provided by Frank Denis obsd-tech@pureftpd.org
ok otto@, millert@
avoid some integer overflows mostly with GLOB_APPEND and GLOB_DOOFFS
and sanity check arguments (these will be unnecessary when we switch
struct glob members from being type into to size_t in the future);
"looks ok" tedu@ feedback guenther@
[openbsd-compat/glob.c]
Extend GLOB_LIMIT to cover readdir and stat and bump the malloc limit
from ARG_MAX to 64K.
Fixes glob-using programs (notably ftp) able to be triggered to hit
resource limits.
Idea from a similar NetBSD change, original problem reported by jasper@.

[sftp.c configure.ac openbsd-compat/glob.c openbsd-compat/glob.h]
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
