This patch implements the missing .import() and .export() mandatory
hooks for asynchronous hash algorithms. It also sets the relevant, non
zero, value for the .statesize field when declaring the supported SHA
algorithms. Indeed a zero value of .statesize prevents the algorithm from
being registered.

The generic crc32 implementation is currently called crc32.  This
is a problem because it clashes with the lib implementation of crc32.

This patch renames the crypto crc32 to crc32_generic so that it is
consistent with crc32c.  An alias for the driver is also added.

mcryptd_create_hash() fails by returning -EINVAL, causing any
driver using mcryptd to fail to load. It is because it needs
to set its statesize properly.

When building the jitterentropy driver by itself, we get a link error
when CRYPTO_RNG is not enabled as well:

crypto/built-in.o: In function `jent_mod_init':
jitterentropy-kcapi.c:(.init.text+0x98): undefined reference to `crypto_register_rng'
crypto/built-in.o: In function `jent_mod_exit':
jitterentropy-kcapi.c:(.exit.text+0x60): undefined reference to `crypto_unregister_rng'

This adds a 'select CRYPTO_RNG' to CRYPTO_JITTERENTROPY to ensure the API
is always there when it's used, not just when DRBG is also enabled.
CRYPTO_DRBG would set it implicitly through CRYPTO_JITTERENTROPY now,
but this leaves it in place to make it explicit what the driver does.

gcc correctly warns that the printk output contains a variable that
it thinks is not initialized in some cases:

drivers/crypto/sunxi-ss/sun4i-ss-cipher.c: In function 'sun4i_ss_cipher_poll':
drivers/crypto/sunxi-ss/sun4i-ss-cipher.c:254:76: warning: 'todo' may be used uninitialized in this function [-Wmaybe-uninitialized]
drivers/crypto/sunxi-ss/sun4i-ss-cipher.c:144:15: note: 'todo' was declared here

A closer look at the function reveals that the variable is always
initialized at this point (ileft is guaranteed to be positive at the
start), but its contents are not well-defined:
Depending on some other variables, it might be either a count in
words or bytes, and it could refer to either input or output.

The easiest solution apparently is to remove the confusing output
and let the reader figure out the state from the other variables.

The _args_digest is defined as _args+_digest, both of which are the first
members of 2 separate structures, effectively yielding _args_digest to have
a value of zero. Thus, no errors have spawned yet due to this. To ensure
sanity, adding the missing _args_digest offset to the sha1_mb_mgr_submit.S.

This patch removes the last reference to hash and ablkcipher from
IPsec and replaces them with ahash and skcipher respectively.  For
skcipher there is currently no difference at all, while for ahash
the current code is actually buggy and would prevent asynchronous
algorithms from being discovered.
