Fixes PR kern/41069 and PR kern/41070.

Extends the Opencrypto API to allow the destination buffer size to be
specified when its not the same size as the input buffer (i.e. for
operations like compress and decompress).
The crypto_op and crypt_n_op structures gain a u_int dst_len field.
The session_op structure gains a comp_alg field to specify a compression
algorithm.
Moved four ioctls to new ids; CIOCGSESSION, CIOCNGSESSION,  CIOCCRYPT,
and CIOCNCRYPTM.
Added four backward compatible ioctls; OCIOCGSESSION, OCIOCNGSESSION,
OCIOCCRYPT, and OCIOCNCRYPTM.

Backward compatibility is maintained in ocryptodev.h and ocryptodev.c which
implement the original ioctls and set dst_len and comp_alg to 0.

Adds user-space access to compression features.

Adds software gzip support (CRYPTO_GZIP_COMP).

Adds the fast version of crc32 from zlib to libkern. This should be generally
useful and provide a place to start normalizing the various crc32 routines
in the kernel.  The crc32 routine is used in this patch to support GZIP.
