allow callers of nfs41_open() and nfs41_create() to pass arbitrary attributes fo
r use with open_args.openhow.how.createattrs and create_args.createattrs
http://msdn.microsoft.com/en-us/library/cc232085%28v=prot.10%29.aspx : "STATUS_INVALID_PARAMETER: An invalid parameter was passed for FileName or FileNameLength, or the target file was open, or the RootDirectory field value was nonzero for a network operation."
as network filesystems are not expected to support this, return STATUS_INVALID_PARAMETER instead of STATUS_NOT_SUPPORTED

fail attempts to set/get reparse points when the filename is no longer than the vnetroot name (plus a \) to prevent these operations on a volume. also adds checks for non-null buffers to pass Set/GetPointInvalidParamTest

instead of appending a fh value when creating a silly rename name,
we'll append a timestamp. using fh value was problematic because
it was creating a filename longer than 64char long which is
currently out max_filename_size.
use RtlUnicodeToUTF8N() instead of RtlUnicodeStringToAnsiString() to preserve unicode filenames; passes fileio test UnicodeOnDiskTest

file can be opened with a delete_on_close flag set. this file can be
opened again as long as opens specify "file_share_delete" access.
after receiving the cleanup irp, the handle enters "delete-pending"
state. opens in this state must fail with status_delete_pending.
file query for standard_info.delete_pending now should return true.
calling setattr with disposition=1 puts the file in "delete-pending"
state.
calling setattr with dispositon=0 will clear delete_on_close only
if file is in "delete-pending" state. otherwise, setattr is ignored.
removing notepad opens file as a directory ifdef
for volume query notepad supplies insufficient buffer space but
doesn't like buffer_too_small error code. it seems to be fine
with partial buffer filled and buffer_overflow error.
entry->filename points to something the app address space. if app was
started and the ctrl-ed c, then when nfsd picks up the upcall it should
check if the pointer is still valid
windows can send a create irp with dispostion representing creation
of the file and specify DesiredAccess of 0.
we were treating no data access as lookup but in this case, we still
need to create a file. so send an open with a read access and
request no delegation to be returned.
in comparing server identities, in previous commit we removed
comparison of the returned clientids.
however, running against the emc server, we ran into issues of data
servers retuning the same server major, minor, and scope identities
but different clientids. we then decided that it's the same data
server.
cb_handle was declared as HANDLE * instead of just HANDLE and then
used as HANDLE. However, ran into issues with WaitOnSingleObject(cb_handle)
never returning.
