The trickiest part about this was getting the sharing and locking
rules right, as alternate streams are separate locking spaces from the
main file for the purposes of byte range locking, and separate for
most share violation rules.
I suspect there are still problems with delete on close with alternate
data streams. I'll look at that next.

(the IDL, and the load/save meta-data logic)
- changed pvfs_resolve_name() to default to non-wildcard, needing
PVFS_RESOLVE_WILDCARD to enable wildcards. Most callers don't want
wildcards, so defaulting this way makes more sense.
- fixed deletion of EAs

BASE-DENYDOS test.
- pvfs now passes BASE-DENY1 and BASE-DENYDOS.

preparation for adding code to pass the BASE-DENY1 and BASE-DENYDOS
tests, which require a shared filesystem handle for some specific
combinations of two DENY_DOS opens on the same connection.

- added initial support for MODE_INFORMATION in setfileinfo (I have no
idea what "mode information" on a file is - it takes a value of 0,
2, 4 or 6. What could it be?)

stored in posix xattrs

attributes of files.
I decided to use IDL/NDR to encode the attribute, as it gives us a
simple way to describe and extend the saved attributes.
The xattr code needs to hook into quite a few more places in the pvfs
code, but this at least gets the basics done. I will start encoding
alternate data streams streams, DOS EAs etc soon using the same basic
mechanism.
I'll probably stick to "version 1" for the xattr.idl for quite a while
even though it will be changing, as I don't expect anyone to be
deploying this in production just yet. Once we have production users
we will need to keep compatibility by supporting all the old version
numbers in xattr.idl.

different type of unlink an seach mismatches
- wildcard directory listings that have attribute
FILE_ATTRIBUTE_DIRECTORY and match "." or ".." should be failed.
- don't set the write_time on SMBclose unless it is non-zero
- added much better support for setfileinfo and setpathinfo in pvfs
- better (and more efficient) handling of .. and . components in filenames

- 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

rather than manual reference counts
- properly support SMBexit in the cifs and posix backends
- added a logoff method to all backends
With these changes the RAW-CONTEXT test now passes against the posix backend

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.

this is still just a skeleton, and many of the functions are just
based on the simple vfs backend, they are there to allow me to run
smbtorture tests against the real parts of the posix backend.
