Subject: nttrans.c:

winreg was missing from the list of pipes.  advise using the array
already defined in... rpc_parse/parse_rpc.c's pipe_names[], but
writing code to strip "\PIPE\" from the front when making the
check.

one location to update when adding new pipes, not two.


srv_pipe_hnd.c:

moved the ZERO_STRUCT(p) macro to _before_ the DLIST_ADD(Pipes, p) macro.

dlinklist.h:

added { }s around the code inserted by DLIST_ADD and DLIST_REMOVE macros
(This used to be commit 29201d4b9b52652c7a992d0f6b677a09b4c33912)
