Commit 5d26a105 ("crypto: prefix module autoloading with "crypto-"")
changed the automatic module loading when requesting crypto algorithms
to prefix all module requests with "crypto-". This requires all crypto
modules to have a crypto specific module alias even if their file name
would otherwise match the requested crypto algorithm.

Even though commit 5d26a105 added those aliases for a vast amount of
modules, it was missing a few. Add the required MODULE_ALIAS_CRYPTO
annotations to those files to make them get loaded automatically, again.
This fixes, e.g., requesting 'ecb(blowfish-generic)', which used to work
with kernels v3.18 and below.

Also change MODULE_ALIAS() lines to MODULE_ALIAS_CRYPTO(). The former
won't work for crypto modules any more.

This can't be NULL and we dereferenced it earlier.  Smatch used to
ignore these things where the pointer was obviously non-NULL but I've
found that sometimes the intention was to check something else so we
were maybe missing bugs.

This patch introduces the multi-buffer job manager which is responsible
for submitting scatter-gather buffers from several SHA1 jobs to the
multi-buffer algorithm.  It also contains the flush routine to that's
called by the crypto daemon to complete the job when no new jobs arrive
before the deadline of maximum latency of a SHA1 crypto job.

The SHA1 multi-buffer crypto algorithm is defined and initialized in
this patch.
