	CHANGES conf.h http_main.c mod_cgi.c mod_userdir.c
-----------------------------------------------------------------
conf.h: Added FLOCK_SERIALIZED_ACCEPT to A/UX
http_main.c: created FLOCK_SERIALIZED_ACCEPT for systems that need it,
 but using fcntl() locking is expensive (esp. running NFS)
mod_cgi.c: Cliff Skolnick's read_client_block check
mod_userdir.c: If we hit the end of the UserDir list, and we haven't
 found a file, return NOT_FOUND; we were returning OK before
 with junk in the r->filename slot
