Rather than store md_len, factor out the common parts of SHA384_Final and
SHA512_Final and then extract the right state. Also add a missing
SHA384_Transform and be consistent about "1" vs "one" in comments.
This also removes the NULL output special-case which no other hash function
had.

stdint.h already has macros for this. The spec says that, in C++,
__STDC_CONSTANT_MACROS is needed, so define it for bytestring_test.cc.
Chromium seems to use these macros without trouble, so I'm assuming we
can rely on them.

The previous logic only defined
|SHA512_BLOCK_CAN_MANAGE_UNALIGNED_DATA| when the assembly language
optimizations were enabled, but
|SHA512_BLOCK_CAN_MANAGE_UNALIGNED_DATA| is also useful when the C
implementations are used.
If support for ARM processors that don't support unaligned access is
important, then it might be better to condition the enabling of
|SHA512_BLOCK_CAN_MANAGE_UNALIGNED_DATA| on ARM based on more specific
flags.

The documentation in md32_common.h is now (more) correct with respect
to the most important details of the layout of |HASH_CTX|. The
documentation explaining why sha512.c doesn't use md32_common.h is now
more accurate as well.
Before, the C implementations of HASH_BLOCK_DATA_ORDER took a pointer
to the |HASH_CTX| and the assembly language implementations took a
pointer to the hash state |h| member of |HASH_CTX|. (This worked
because |h| is always the first member of |HASH_CTX|.) Now, the C
implementations take a pointer directly to |h| too.
The definitions of |MD4_CTX|, |MD5_CTX|, and |SHA1_CTX| were changed to
be consistent with |SHA256_CTX| and |SHA512_CTX| in storing the hash
state in an array. This will break source compatibility with any
external code that accesses the hash state directly, but will not
affect binary compatibility.
The second parameter of |HASH_BLOCK_DATA_ORDER| is now of type
|const uint8_t *|; previously it was |void *| and all implementations
had a |uint8_t *data| variable to access it as an array of bytes.
This change paves the way for future refactorings such as automatically
generating the |*_Init| functions and/or sharing one I-U-F
implementation across all digest algorithms.

The SHA-2 family has some exceptions, but they're all programmer errors
and should be documented as such. (Are the failure cases even
necessary?)

Use sized integer types rather than unsigned char/int/long. The latter
two are especially a mess as they're both used in lieu of uint32_t.
Sometimes the code just blindly uses unsigned long and sometimes it uses
unsigned int when an LP64 architecture would notice.

This is an initial cut at aarch64 support. I have only qemu to test it
however—hopefully hardware will be coming soon.
This also affects 32-bit ARM in that aarch64 chips can run 32-bit code
and we would like to be able to take advantage of the crypto operations
even in 32-bit mode. AES and GHASH should Just Work in this case: the
-armx.pl files can be built for either 32- or 64-bit mode based on the
flavour argument given to the Perl script.
SHA-1 and SHA-256 don't work like this however because they've never
support for multiple implementations, thus BoringSSL built for 32-bit
won't use the SHA instructions on an aarch64 chip.
No dedicated ChaCha20 or Poly1305 support yet.
