[proof of concept] libwbclient.so

Folks,

Attached is a very basic POC of how to build a libwbclient.so
which can be linked into application for accessing the
winbindd API.  I've only included the lookupname() call

  $ gcc -o wbinfo-test main.c -lwbclient

  $ ./wbinfo AD gcarter
  S-1-5-21-3234968684-14787312-124015166-3136 (1)

The goal is to remove the tight coupling between smbd and
winbindd so that Winbind can be developed independently
of smbd.  Currently smbd is hard coded to a specific
WINBIND_INTERFACE_VERSION.  What I'm doing is to allow
smbd to link against a library that carries that dependency
instead.  So that if you need to upgrade winbindd, as long
as the libwbclient maintains a compatible API, one can
replace winbindd without having to upgrade or recompile
smbd as well.

This plays into the marshalling proposal for the winbind pipe
that has been discussed in the past but does not interfere with
it as it provides the 3rd-party application access and does not
concern itself with how the bits are written onto the domain
socket to communicate with winbindd.  That can be changed
without impacting the high level API.

The main steps of development are agreement on an API and
the Makefile changes to link smbd against libwbclient rather
than the Winbind *.o files.



cheers, jerry
