was incorrectly using file_attributes instead of create attributes to check
if we are creating a file or a directory. it lead to creating directories
with archive set.
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

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.
adding -o timeout=value (in sec) mount option to override a default
timeout value for the upcalls for non-io upcalls. Default timeout is
at least the lease_time seconds of an established mount or 20secs.
read/write upcall also take into account number of bytes for the request
and 100MB/s network speed and 100MB/s disk speed
changing the code to keeping track of fcbs and not srv_opens.
problem of keeping srv_opens was that we could get an open for
attribute which will then do a setacl which will modify a change
attribute of the file but because the open is not for reading
data we won't have it on the list of opens.
