errors etc.) into locking/posix.c, where it is needed. fcntl_lock in lib/util.c
is now very small and clean.
Added (*lock) op to vfs layer.

new open mechanism Andrew & I discussed.
config.sub:
configure: Included the QNX patch.
include/vfs.h:
smbd/vfs-wrap.c:
smbd/vfs.c: Added ftruncate vfs call (needed).
Note that we will also need locking calls in the vfs (to be added).
lib/util_unistr.c:
nmbd/nmbd_processlogon.c: Fix for NT domain logons causing nmbd to core dump.
Also fix for sidsize DOS bug.
locking/locking.c: Check value of ret before using it for memdup.
printing/printing.c: Convert print_fsp_open to return an allocated fsp.
rpc_server/srv_lsa.c: Fix for NT domain logons.
I have removed all use of lp_share_modes() from the code (although I
left the parameter in the table for backwards compatibility). It no longer makes
sense for this to exist.
smbd/close.c: Removed lp_share_modes().
smbd/fileio.c: Fixed parameters to unlock_share_entry call in panic code.
smbd/files.c: Correctly set the unix_ERR_code to ERRnofids on fsp allocation fail.
smbd/nttrans.c:
smbd/reply.c:
smbd/trans2.c: Changed all occurrences of open_file_shared/open_directory/
open_file_stat to return an fsp from the call.
smbd/open.c: Changed all occurrences of open_file_shared/open_directory/
open_file_stat to return an fsp from the call.
In addition I have fixed a long standing race condition in the deny mode
processing w.r.t. two smbd's creating a file. Andrew, please note that
your original idea of using open with O_EXCL in this case would not work
(I went over the races very carefully) and so we must re-check deny modes
*after* the open() call returns. This is because there is a race between
the open with O_EXCL and the lock of the share mode entry. Imagine the
case where the first smbd does the open with O_EXCL and a deny mode of DENY_ALL,
but is pre-empted before it locks the share modes and creates the deny
mode entry for DENY_ALL. A second smbd could then come in with O_RDONLY
and a deny mode of DENY_NONE and the two opens would be allowed.
The *only* way to fix this race is to lock the share modes after the
open and then do the deny mode checks *after* this lock in the case
where the file did not originally exist.
This code will need extensive testing but seems to initially work.
Jeremy.

handling to printing/printing.c
most of this was just replacing things like fsp->fd_ptr->fd with fsp->fd
the changes in open.c are quite dramatic. Most of it is removing all
the functions that handled the fd multiplexing

Removed unnecessary SSL stuff from vfs_write_data().

Converted some useful routines from doscalls.c and changed them to use
VFS I/O functions:
dos_file_exist
dos_read_data
dos_write_data
dos_transfer_file
dos_readdirname
Some of these functions have been #ifdef'ed out of doscalls.c as they
are not used anywhere else. Not sure whether they should be deleted
or not. The remaining dos_* calls seem to be used by clients and for
locking stuff. This should be cleaned up sometime.
