9ef33f5f5c r15734: This is a major change to the NTVFS subsystem:
- to use a struct ntvfs_handle instead of a uint16_t fnum.
  (to make it independend from the frontend protocol)
- the allocation of handles now is provided by the frontend
  (smbsrv_*) via callbacks and not by each backend module
- this also makes sure that file handles are only passed
  to the ntvfs subsystem when the tcon and session matches,
  so modules can rely on this and need to check this.
- this allows multiple modules in the ntvfs module chain
  to allocate file handles. This can be used for virtual
  files like "\\$Extend\\$Quota:$Q:$INDEX_ALLOCATION"...
- also this will make SMB2 with 128 bit file handles possible

dcad0f6fd4 r2751: this is a new ntvfs design which tries to solve:
- the stacking of modules
- finding the modules private data
- hide the ntvfs details from the calling layer
- I set NTVFS_INTERFACE_VERSION 0 till we are closer to release
  (because we need to solve some async problems with the module stacking)

5b44130afa r2671: we're getting too many errors caused by the talloc_realloc() API not
taking a context (so when you pass a NULL pointer you end up with
memory in a top level context). Fixed it by changing the API to take a
context. The context is only used if the pointer you are reallocing is
NULL.

a3cec511bb r2561: completely redid the ntvfs module chaining code, You can now do something like:
ntvfs handler = nbench posix

and the nbench pass-thru module will be called before the posix
module. The chaining logic is now much saner, and less racy, with each
level in the chain getting its own private pointer rather than relying
on save/restore logic in the pass-thru module.

The only pass-thru module we have at the moment is the nbench one
(which records all traffic in a nbench compatibe format), but I plan
on soon writing a "unixuid" pass-thru module that will implement the
setegid()/setgroups()/seteuid() logic for standard posix uid
handling. This separation of the posix backend from the uid handling
should simplify the code, and make development easier.

I also modified the nbench module so it can do multiple chaining, so
if you want to you can do:

   ntvfs module = nbench nbench posix

and it will save 2 copies of the log file in /tmp. This is really only
useful for testing at the moment until we have more than one pass-thru
module.
