sha512_base.h is no longer used, so remove it.

Delete crypto/sha512_generic.c, which provided "generic" SHA-384 and
SHA-512 crypto_shash algorithms. Replace it with crypto/sha512.c which
provides SHA-384, SHA-512, HMAC-SHA384, and HMAC-SHA512 crypto_shash
algorithms using the corresponding library functions.
This is a prerequisite for migrating all the arch-optimized SHA-512 code
(which is almost 3000 lines) to lib/crypto/ rather than duplicating it.
Since the replacement crypto_shash algorithms are implemented using the
(potentially arch-optimized) library functions, give them
cra_driver_names ending with "-lib" rather than "-generic". Update
crypto/testmgr.c and one odd driver to take this change in driver name
into account. Besides these cases which are accounted for, there are no
known cases where the cra_driver_name was being depended on.
This change does mean that the abstract partial block handling code in
crypto/shash.c, which got added in 6.16, no longer gets used. But
that's fine; the library has to implement the partial block handling
anyway, and it's better to do it in the library since the block size and
other properties of the algorithm are all fixed at compile time there,
resulting in more streamlined code.

Now that all sha256_base users have been converted to use the API
partial block handling, remove the partial block helpers.

Use the Crypto API partial block handling.
Also remove the unnecessary SIMD fallback path.

asm/unaligned.h is always an include of asm-generic/unaligned.h;
might as well move that thing to linux/unaligned.h and include
that - there's nothing arch-specific in that header.
auto-generated by the following:
for i in `git grep -l -w asm/unaligned.h`; do
sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i

Currently <crypto/sha.h> contains declarations for both SHA-1 and SHA-2,
and <crypto/sha3.h> contains declarations for SHA-3.
This organization is inconsistent, but more importantly SHA-1 is no
longer considered to be cryptographically secure. So to the extent
possible, SHA-1 shouldn't be grouped together with any of the other SHA
versions, and usage of it should be phased out.
Therefore, split <crypto/sha.h> into two headers <crypto/sha1.h> and
<crypto/sha2.h>, and make everyone explicitly specify whether they want
the declarations for SHA-1, SHA-2, or both.
This avoids making the SHA-1 declarations visible to files that don't
want anything to do with SHA-1. It also prepares for potentially moving
sha1.h into a new insecure/ or dangerous/ directory.

Without the barrier_data() inside memzero_explicit(), the compiler may
optimize away the state-clearing if it can tell that the state is not
used afterwards.

To reduce the number of copies of boilerplate code throughout
the tree, this patch implements generic glue for the SHA-512
algorithm. This allows a specific arch or hardware implementation
to only implement the special handling that it needs.
The users need to supply an implementation of
void (sha512_block_fn)(struct sha512_state *sst, u8 const *src, int blocks)
and pass it to the SHA-512 base functions. For easy casting between the
prototype above and existing block functions that take a 'u64 state[]'
as their first argument, the 'state' member of struct sha512_state is
moved to the base of the struct.
