Add a more sane socket registration interface.

Previously, it was messed up because Greg's struct class hadn't been
invented when I wrote the code: there may be multiple sockets per
"struct device", and there is the need for one "struct class_device"
for each socket.

Split up the socket initialization in cs.c into two pieces:

        pcmcia_register_socket / pcmcia_unregister_socket 
will focus on registering sockets with the device core in future, set
all necessary fields etc.

        pcmcia_add_socket / pcmcia_remove_socket 
will use an interface to the device class "pcmcia_socket_class" in
future, and mainly take care of what initialization cs.c needs to work
properly.

This patch is almost completely limited to shuffling code around

If we use try_module_get(driver->owner) at the right place (and
module_put as well, of course), the check for (driver->use_count > 0)
can't ever return true. So get rid of it, and add the proper module
locking calls.

This patch removes the socket_table from cs.c and friends.

This adds a list of all pcmcia sockets which will replace the current
table-based approach. Also, ds.c now relies on cs.c to get the proper
"struct pcmcia_bus_socket *" for the corresponding socket number.

This patch introduces "struct pcmcia_socket" which is 100% equal to
the "socket_info_t" defined previously in drivers/pcmcia/cs_internal.h

Unfortunately, a few other definitons need to be moved as well.

When foo is unlinked, nfs_unlink() does a sillyrename, this puts the
dentry on nfs_delete_queue, and (in the VFS) unhashes it from the
dcache.  This causes problems, since any later access to the
silly-renamed new .nfs file will create a NEW dentry that aliases the
one we originally created, but unhashed.

This causes various confusion, especially if we want to try to delete it
again later.

So fix this by not unhash the dentry after silly-renaming.  In 2.2, each
fs was responsible for doing a d_delete(), in 2.4 and later it happens
in the VFS layer and I think it was just an oversight that the 2.4 VFS
doesn't consider sillyrename (considering the code and comments that are
cruft).

Also fixed up some comments while debugging this.

Pull dm_div_up() out of dm-table.c into dm.h

Some targets may perform io of their own volition, eg. a mirror
performing recovery, a cache target pulling in different chunks.  We
cannot let them perform this io while the device is suspended.  This
patch adds 2 new methods to the target type, which instruct the target
to suspend/resume itself.  All targets start in the suspended state,
so should expect an initial resume call.  Simple targets do not need
to implement these functions.

Replace __HIGH() and __LOW() with max() and min_not_zero().

This removes the last sources of "non-ANSI parameter list" warnings for
zlib_deflate.

Reduce MAX_MEM_LEVEL to 8.  This reduces zlib memory consumption by
128k (from ~400k to ~270k) at the theoretical cost of worse
compression.  No code currently in the kernel actually uses the better
compression, so the practical cost is zero.

chr_dev_init() should be a subsys_initcall(), since it needs to
initialize before any drivers that use the character device
infrastructure.

force windowBits > 8 to avoid a bug in the encoder for a window size
of 256 bytes. (A complete fix will be available in 1.1.5).

James Carlson:

        The problem is that s->strstart gets set to a very large
        positive integer when wsize (local copy of s->w_size) is
        subtracted in deflate.c:fill_window().  This happens because
        MAX_DIST(s) resolves as a negative number when the window size
        is 8 -- MAX_DIST(s) is defined as s->w_size-MIN_LOOKAHEAD in
        deflate.h.  MIN_LOOKAHEAD is MAX_MATCH+MIN_MATCH+1, and that
        is 258+3+1 or 262.  Since a window size of 8 gives s->w_size
        256, MAX_DIST(s) is 256-262 or -6.

        This results in read_buf() writing over memory outside of
        s->window, and a crash.

Don't think anyone actually bothers to check specific error codes, but
it shouldn't hurt either.
