Restructuring of vfs layer to include a "this" pointer - can be an fsp or

a conn struct depending on the call.
We need this to have a clean NT ACL call interface.
This will break any existing VFS libraries (that's why this is pre-release
code).
Andrew gets credit for this one :-) :-).

In addition - added Herb's WITH_PROFILE changes - Herb - please examine
the changes I've made to the smbd/reply.c code you added. The original
code was very ugly and I have replaced it with a
START_PROFILE(x)/END_PROFILE(x) pair using the preprocessor.
Please check this compiles ok with the --with-profile switch.
Jeremy.
