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.

This removes unnecessary NULL casting.
