run into kernel oplocks on an open for a stream inside a file with stream_xattr module. On
opening the base_fsp we must break existing oplocks." as it broke make test.

Restructures parts of open code so that fsp must be allocated before calling
open_file_ntcreate(_internal). Also fix up file ref-counting inside files.c.

to specific bits every time a security descriptor is set. The S4 torture suite proves
that generic bits are not returned when querying an ACL set using them (ie. only
the specific bits are stored on disk).
Jeremy.
We don't need to deny a DELETE open on a readonly file (I'm also adding a s4
torture test for this), the set_file_disposition call will return
NT_STATUS_CANNOT_DELETE if the delete-on-close bit is set
on a readonly file (and we already do this).
Jeremy.
Some of the bits generate INVALID_PARAMETER and some bits
are ignored when they come from a client, that's why we need
to use bits from the ignored range for our internal usage.

current_user_info was "only" used in a debug msg, and current_user.ut.uid is
also available via conn->server_info
(This used to be commit d0386914ff0f7b0f1edc3302fdc6a25f211712fa)
The current vuid is not only available there, it is also in the current
smb_request structure.

This hides the pending close fds from the outside. Call order
of SMB_VFS_CLOSE is reversed. Originally, it was:
fd_close -> fd_close_posix -> SMB_VFS_CLOSE -> close
And now it is:
fd_close -> SMB_VFS_CLOSE -> fd_close_posix -> close
This is in preparation of removing the fd parameter
from the SMB_VFS_CLOSE function. But it is also the right
place for the pending close calls anyways.

This is needed to implement the strange write time update
logic later. We need to store 2 time timestamps to
distinguish between the time the file system had before
the first client opened the file and a forced timestamp update.

SET_STAT_INVALID only sets nlink, not the other fields
We might consider to change SET_STAT_INVALID to always do ZERO_STRUCT

Found by a "set but never used" warning. Thanks to talloc_tos() this was not
really a bug, but this way the code becomes much clearer.

new stream code. (1) In smbd/filename, don't split the name at
':' if we know it's a posix path (this should be parameterized....).
(2). When calling posix_mkdir, we get the flag FILE_FLAG_POSIX_SEMANTICS
passed to open_directory(). I know for a posix client lp_posix_pathnames
should be true (which is checked for in is_ntfs_stream_name() but we
have an explicit flag here, so let's use it.

This is the core of the streams support. The main change is that in
files_struct there is now a base_fsp pointer that holds the main file open
while a stream is open. This is necessary to get the rather strange delete
semantics right: You can't delete the main file while a stream is open without
FILE_SHARE_DELETE, and while a stream is open a successful unlink of the main
file leads to DELETE_PENDING for all further access on the main file or any
stream.
