Initialization by multiple consumers on ARM is still problematic due to
CRYPTO_set_NEON_{capable,functional}, until we reimplement that in-library, but
if that is called before the first CRYPTO_library_init, this change makes it
safe.

There's a few things that will be kind of a nuisance and possibly not worth it
(crypto/asn1 dumps a lot of undeclared things, etc.). But it caught some
mistakes. Even without the warning, making sure to include the externs before
defining a function helps catch type mismatches.

Some ARM environments don't support |getauxval| or signals and need to
configure the capabilities of the chip at compile time. This change adds
defines that allow them to do so.

arm_arch.h is included from ARM asm files, but lives in crypto/, not
openssl/include/. Since the asm files are often built from a different
location than their position in the source tree, relative include paths
are unlikely to work so, rather than having crypto/ be a de-facto,
second global include path, this change moves arm_arch.h to
include/openssl/.
It also removes entries from many include paths because they should be
needed as relative includes are always based on the locations of the
source file.

SSLeay is a compatibility function for OpenSSL, but I got it wrong. It
doesn't return a string, it returns a number. This doesn't end up making
any difference, but it fixes a warning when building OpenSSH.

OpenSSH, especially, does some terrible things that mean that it needs
the EVP_CIPHER structure to be exposed ☹. Damian is open to a better API
to replace this, but only if OpenSSL agree too. Either way, it won't be
happening soon.

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.

Chromium does not like static initializers, and the CPU logic uses one to
initialize CPU bits. However, the crypto library lacks an explicit
initialization function, which could complicate (no compile-time errors)
porting existing code which uses crypto/, but not ssl/.
Add an explicit CRYPTO_library_init function, but make it a no-op by default.
It only does anything (and is required) if building with
BORINGSSL_NO_STATIC_INITIALIZER.
