This reverts commit a6ae7a552f851a399991262377cc0e062e40ac20.
This fixes bug #7222 (All users have full rigths on all shares) (CVE-2010-0728).

Ensure we don't use any of the create_options for Samba private
use. Add a new parameter to the VFS_CREATE call (private_flags)
which is only used internally. Renumber NTCREATEX_OPTIONS_PRIVATE_DENY_DOS
and NTCREATEX_OPTIONS_PRIVATE_DENY_FCB to match the S4 code).
Rev. the VFS interface to version 28.

On filesystems that can't store less than one second timestamps,
round the incoming timestamp set requests so the client can't discover
that a time set request has been truncated by the filesystem.

s3: Make smbd aware of permission change of usershare. Since usershare are relatively volatile and
non-previledge users must disconnect from smbd and reconnect to it to make share permission in effect.
For now. This is a feature request and I think we need
to design it a little differently so as not to touch
core change_to_user() code.

Before 3.3, an smbcontrol debug message sent to the target "smbd" would
actually be sent to all running processes including nmbd and winbindd.
This behavior was changed in 3.3 so that the "smbd" target would only
send a message to the process found in smbd.pid, while the "all" target
would send a message to all processes.
The ability to set the debug level of all processes within a single
daemon, without specifying each pid is quite useful. This was implemented
in winbindd in 065760ed. This patch does the same thing for smbd.
Upon receiving a MSG_DEBUG the parent smbd will rebroadcast it to all of
its children.
The printing process has been added to the list of smbd child processes,
and we now always track the number of smbd children regardless of the
"max smbd processes" setting.

All paths are now unix paths, making this flag useless.
This flags argument is now unused and can be safely removed.

This is the first of a series of patches that change path based
operations to operate on a struct smb_filename instead of a char *.
This same concept already exists in source4.
My goals for this series of patches are to eventually:
1) Solve the stream vs. posix filename that contains a colon ambiguity
that currently exists.
2) Make unix_convert the only function that parses the stream name.
3) Clean up the unix_convert API.
4) Change all path based vfs operation to take a struct smb_filename.
5) Make is_ntfs_stream_name() a constant operation that can simply
check the state of struct smb_filename rather than re-parse the
filename.
6) Eliminate the need for split_ntfs_stream_name() to exist.
My strategy is to start from the inside at unix_convert() and work my
way out through the vfs layer, call by call. This first patch does
just that, by changing unix_convert and all of its callers to operate
on struct smb_filename. Since this is such a large change, I plan on
pushing the patches in phases, where each phase keeps full
compatibility and passes make test.
The API of unix_convert has been simplified from:
NTSTATUS unix_convert(TALLOC_CTX *ctx,
connection_struct *conn,
const char *orig_path,
bool allow_wcard_last_component,
char **pp_conv_path,
char **pp_saved_last_component,
SMB_STRUCT_STAT *pst)
to:
NTSTATUS unix_convert(TALLOC_CTX *ctx,
connection_struct *conn,
const char *orig_path,
struct smb_filename *smb_fname,
uint32_t ucf_flags)
Currently the smb_filename struct looks like:
struct smb_filename {
char *base_name;
char *stream_name;
char *original_lcomp;
SMB_STRUCT_STAT st;
};
One key point here is the decision to break up the base_name and
stream_name. I have introduced a helper function called
get_full_smb_filename() that takes an smb_filename struct and
allocates the full_name. I changed the callers of unix_convert() to
subsequently call get_full_smb_filename() for the time being, but I
plan to eventually eliminate get_full_smb_filename().

We store the seqnum/mid mapping in the cli_request structure
for async requests and in the cli_state structure for sync calls.
We skip the signing check for oplock requests while waiting
for async requests coming in.
