lib/crypto: x86/sha1: Migrate optimized code into library
Instead of exposing the x86-optimized SHA-1 code via x86-specific
crypto_shash algorithms, instead just implement the sha1_blocks()
library function. This is much simpler, it makes the SHA-1 library
functions be x86-optimized, and it fixes the longstanding issue where
the x86-optimized SHA-1 code was disabled by default. SHA-1 still
remains available through crypto_shash, but individual architectures no
longer need to handle it.
To match sha1_blocks(), change the type of the nblocks parameter of the
assembly functions from int to size_t. The assembly functions actually
already treated it as size_t.
