Turning on blocking locking code. NB. Blocking lock requests that are not

the head of an SMB request (ie. are part of a chain) will not be queued -
this will be fixed when we move to the new chain code. In practice, this
doesn't seem to cause much of a problem (in my admittedly limited testing)
bug a debug level zero message will be placed in the log when this
happens to help determine how real the problem is.

smbd/locking.c: New debug messages.
smbd/blocking.c: New blocking code - handles SMBlock, SMBlockread and SMBlockingX
smbd/chgpasswd.c: Fix for master fd leak.
smbd/files.c: Tidyup comment.
smbd/nttrans.c: Added fnum to debug message.
smbd/process.c: Made chain_reply() use construct_reply_common(). Added blocking
                lock queue processing into idle loop.
smbd/reply.c: Added queue pushes for SMBlock, SMBlockread and SMBlockingX.
Jeremy.
