The problem was twofold:
1) irix returns 64 bit numbers in telldir(). The protocol uses a 32
bit resume key. We now cope with this properly using the code in
pvfs_list_seek_ofs().
2) irix returns 0xFFFFFFFF from telldir() for the last entry in the
directory. When added to DIR_OFFSET_BASE this became
DIR_OFFSET_DOTDOT which meant an infinite loop!

test to pass. To try to make the code a bit more understandable, I
moved to using an IDL description of the opendb tdb record format.
One of the larger changes was to make directory opens and creates go
via the opendb code, so directory operations now obey all the share
mode restrictions, as well as delete on close semantics. I also
changed the period over which the opendb locks are held, to try to
minimise races due to two open operations happening at the same time.

talloc(ctx, 0) call.
- cleaned up some talloc usage in various files
I'd like to get to the point that we have no calls to talloc(), at
which point we will rename talloc_p() to talloc(), to encourage
everyone to use the typesafe functions.

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

- 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

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.
