s3-rpc_server: Create common function to allocate pipes_struct
Avoid code duplication and fix bug where a new pipe was not added to
InternalPipes upon creation in make_server_pipes_struct()

commit 759a04e58a88b400dbf0cafc2b86ab58ea196433
Author: Simo Sorce <idra at samba.org>
Date: Thu Jul 21 09:53:10 2011 -0400
s3-rpc_server: Move pipe/handles functions
Put InternalPipes related functions in rpc_handles.c and out of rpc_ncacn_np.c
rpc_handles.c is the only file that really uses them after all and ncacn_np.c
is the wrong place for that stuff.
While ther remove unnecessary wrapper functions now that the InternalPipes
static variable is directly accessible.
Also move all pipes_struct related header stuff in its own rpc_pipes.h header.
