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.

While converting ecryptfs over to skcipher I found that it needs
to pick a default key size if one isn't given.  Rather than having
it poke into the guts of the algorithm to get max_keysize, let's
provide a helper that is meant to give a sane default (just in
case we ever get an algorithm that has no maximum key size).
