crypto: lib/sha1 - fold linux/cryptohash.h into crypto/sha.h
<linux/cryptohash.h> sounds very generic and important, like it's the
header to include if you're doing cryptographic hashing in the kernel.
But actually it only includes the library implementation of the SHA-1
compression function (not even the full SHA-1). This should basically
never be used anymore; SHA-1 is no longer considered secure, and there
are much better ways to do cryptographic hashing in the kernel.
Remove this header and fold it into <crypto/sha.h> which already
contains constants and functions for SHA-1 (along with SHA-2).
