r10694: Add some work I did this afternoon on getting pidl to output Samba3

RPC parsers. Currently the following files can be generated:

- include/rpc_BASENAME.h
- rpc_server/srv_BASENAME.c
- rpc_server/srv_BASENAME_nt.c (template only, user has to fill in functions)
- rpc_client/cli_BASENAME.c
- rpc_parse/parse_BASENAME.c

So far, I have been working on getting DFS working. Currently still to do
(all in rpc_parse/parse_BASENAME.c):
 - Proper handling of declarations
 - Proper handling of scalar/buffer parts of structs and unions
 - Subcontexts
 - Proper handling of arrays
 - Support for custom (non-scalar) types

I hope to have a somewhat more working version later this week.

Some files as currently generated are available from:
http://samba.org/~jelmer/pidl_samba3/
(This used to be commit 8af8eaeeef6d46f4d25ccb1d25890e1eef063e4f)
