lib/zlib: DFLTCC always switch to software inflate for Z_PACKET_FLUSH option
Since hardware inflate does not support Z_PACKET_FLUSH option (used
exclusively by kernel PPP driver), always switch to software like we
already do for Z_BLOCK flush option. Without this patch, PPP might get
Z_DATA_ERROR return code from zlib_inflate() and disable zlib compression
for the packets.

lib/zlib: DFLTCC support inflate with small window
There is no hardware control for DFLTCC window size. After this change,
software and hardware window formats no longer match: the software will
use wbits and wsize, and the hardware will use HB_BITS and HB_SIZE.
Since neither dictionary manipulation nor internal allocation functions
are relevant to kernel zlib and zlib_inflate_workspacesize() always use
MAX_WBITS for window size calculation, only dfltcc_can_inflate() and
dfltcc_inflate() functions are affected by this patch.

lib/zlib: Split deflate and inflate states for DFLTCC
Currently deflate and inflate both use a common state struct. There are
several variables in this struct that we don't need for inflate, and
more may be coming in the future. Therefore split them in two separate
structs.
Apart from that, introduce separate headers for dfltcc_deflate and
dfltcc_inflate.

lib/zlib: fix inflating zlib streams on s390
Decompressing zlib streams on s390 fails with "incorrect data check"
error.
Userspace zlib checks inflate_state.flags in order to byteswap checksums
only for zlib streams, and s390 hardware inflate code, which was ported
from there, tries to match this behavior. At the same time, kernel zlib
does not use inflate_state.flags, so it contains essentially random
values. For many use cases either zlib stream is zeroed out or checksum
is not used, so this problem is masked, but at least SquashFS is still
affected.
Fix by always passing a checksum to and from the hardware as is, which
matches zlib_inflate()'s expectations.

s390/boot: add dfltcc= kernel command line parameter
Add the new kernel command line parameter 'dfltcc=' to configure s390
zlib hardware support.
Format: { on | off | def_only |
s390/boot: add dfltcc= kernel command line parameter
Add the new kernel command line parameter 'dfltcc=' to configure s390
zlib hardware support.
Format: { on | off | def_only | inf_only | always }
on: s390 zlib hardware support for compression on
level 1 and decompression (default)
off: No s390 zlib hardware support
def_only: s390 zlib hardware support for deflate
only (compression on level 1)
inf_only: s390 zlib hardware support for inflate
only (decompression)
always: Same as 'on' but ignores the selected compression
level always using hardware support (used for debugging)

lib/zlib: add s390 hardware support for kernel zlib_inflate
Add decompression functions to zlib_dfltcc library. Update zlib_inflate
functions with the hooks for s390 hardware support and adjust workspace
structures with extra parameter lists required for hardware inflate
decompression.
