Makefile.in: Moved blocking lock code into smbd/blocking.c for link purposes.

include/includes.h: Added nterr.h.
locking/locking.c: Moved blocking lock code into smbd/blocking.c for link purposes.
smbd/close.c: Added blocking lock removal to file close.
smbd/filename.c: Tidied up unix_convert() so I could read it (:-) in preparation
                 for the stat_cache code.
smbd/nttrans.c: Added WRITE_ATTRIBUTES check.
smbd/reply.c: Fixed multibyte char problem in wildcard mask.
Jeremy.
