mount.cifs: use lock/unlock_mtab scheme from util-linux-ng mount prog
The util-linux-ng sources have a good, but rather complex scheme for
locking the mtab before updating it. Mount helpers need to follow the
same scheme. Advisory locking only works if everyone is using the same
locking scheme.
Copy the routines we need from util-linux-ng into a separate source file
and then have mount.cifs and umount.cifs link in this object.
The long term goal is to have these routines in a separate helper
library (libmount). Mount helpers can then dynamically link in that lib.
Until that happens, this should serve as a suitable stopgap solution.
saf_join_store() should be called after a successful
domain join, the affinity to the dc used at join time
has a larger ttl, to avoid problems with delayed replication.

winbind: fix smbd hanging on Solaris when winbindd closes socket.
On some versions of Solaris, we observed a strange effect of close(2)
on a socket: After the server (here winbindd) called close, the client fd
was not marked as readable for select. And a write call to the fd did
not produce an error EPIPE but just returned as if successful.
So while winbindd had called remove_client(), the corresponding smbd
still thought that it was connected, but failed to retrieve answers
for its queries.
This patch works around the problem by forcing the client fd to
the readable state: Just write one byte into the socket before
closing.

Fix bug #5814 - Winbindd dumping core in a strange manner while doing "rescan_trusted_domain".
From analysis by hargagan <shargagan@novell.com> :
"The winbindd_child_died() is also getting called from process_loop() in case of
SIGCHLD signal. In this case it doesn't make the timeout_handler to NULL for
the first request. It then initiate a new request using
schedule_async_request() which installs a new timeout handler for the same
request. In such a case, for a badly unresponsive system both the timeout
handler can be called. For the first call the "private_data" will be cleared
and for another call the timeout handler will be detecting the double free. So,
for such a case as well, the winbindd_child_died() should make the
timeout_handler to NULL."

Fix use of DLIST_REMOVE as spotted by Constantine Vetoshev <gepardcv@gmail.com>.
This API is unusual in that if used to remove a non-list head it nulls out
the next and prev pointers. This is what you want for debugging (don't want
an entry removed from the list to be still virtually linked into it) but
means there is no consistent idiom for use as the next and prev pointers
get trashed on removal from the list, meaning you must save them yourself.
You can use it one way when deleting everything via the head pointer, as
this preserves the next pointer, but you *must* use it another way when not
deleting everything via the head pointer. Fix all known uses of this (the main
one is in conn_free_internal() and would not free all the private data entries
for vfs modules. The other changes in web/statuspage.c and winbindd_util.c
are not strictly neccessary, as the head pointer is being used, but I've done
them for consistency. Long term we must revisit this as this API is too hard
to use correctly.

mount.cifs: fix several problems when mounting subdirectories of shares (try 2)
This patch is the second patch to attempt to fix up some of the problems
with mounting subdirectories of shares. The earlier patch didn't handle
this correctly when POSIX extensions were enabled. This one does.
This is a bit of a confusing area since the different components of
a service string have different rules:
1) hostname: no '/' (slash) or '\' (backslash) is allowed to be
embedded within the string
2) sharename: same rules as hostname
3) prefixpath: '\' *is* allowed to be embedded in a path component,
iff POSIX extensions are enabled. Otherwise, neither
character is allowed.
The idea here is to allow either character to act as a delimiter when we
know that the character can't be anything but a delimiter (namely
everywhere up to the start of the prefixpath). The patch will convert
any '\' unconditionally to '/' in the UNC portion of the string.
However, inside the prefixpath, we can't make assumptions about what
constitutes a delimiter because POSIX allows for embedded '\'
characters. So there we don't attempt to do any conversion, and pass the
prefixpath to the kernel as is. Once the kernel determines whether POSIX
extensions are enabled, it can then convert the path if needed and it's
able to do so. A patch to handle this has already been committed to the
cifs-2.6 git tree.
This patch also fixes an annoyance. When you mount a subdir of a share,
mount.cifs munges the device string so that you can't tell what the
prefixpath is. So if I mount:
//server/share/p1/p2/p3
..then /proc/mounts and mtab will show only:
//server/share
Finally, it also tries to apply some consistent rules to the uppercasing
of strings.
