Custom named pipes

In case someone else is interested in the hacks: I attached a gzipped patch
with all the changes since 2.2.5.
The configuration of a named pipe is done in the smb.conf file like this:
share type = IPC
path = /var/tmp
The 'share type = IPC' parameter tells smbd that this share is a named pipe.
The 'path' locates where the local unix pipe should be created.
In case path is not defined, path will be '/tmp'.
There are some incompatibilities:
1) There's no full-duplex support:
The server part can only write data and the client part can only
In case you want to write data to both sides, you'll need 2 pipes.
Two chat programs are added in the examples/libsmbclient directory.
One is intended for a windows platform, the other for linux.
Both can receive and send data from/to each other.
2) In case the unix program stops reading its local unix queue,
the named pipe connection will still remain.
The windows program will only receive the "broken pipe" error when
it writes something in the pipe.
3) In case the windows server program breaks the connection, the unix client
program won't see a thing because it's reading a local (unix) named pipe
which is filled by smbd.
4) Somehow, I'm unable to open a named pipe on the same pc (samba<->samba).
I haven't tested it yet with another remote samba server.
