FIPS prescribes a slightly different key generation algorithm than we
use. Specifically:
- Rather than using BN_RAND_TOP_TWO (so using 1.5 as an upper bound for
sqrt(2)), it prescribes using sqrt(2) itself. To avoid unnecessary
squaring, we do a comparison against a hard-coded approximation for
sqrt(2) good enough for the largest FIPS key size. I went ahead and
made it constant-time since it was easy, but all this is far from
constant-time.
- FIPS requires a check that |p-q| is sufficiently large.
- FIPS requires a check that d is sufficiently large.
- BN_generate_prime_ex adds some delta to clear a table of prime
numbers. FIPS does not specify any of that, so implement a separate
routine here.
The primality test itself will be aligned in a follow-up. For now, it is
left unchanged, except that trial division is turned back on. That makes
things faster and is analogous the original algorithm's delta-munging
logic.

Previously, inject-hash would run the FIPS module in order to trigger a
failure and then extract the calculated hash value from the output. This
makes cross-compiling difficult because the build process needs to run a
binary for the target platform.
This change drops this step. Instead, inject-hash.go parses the object
file itself and calculates the hash without needing to run the module.

In some cases, consumers may include a BoringSSL header without setting
up include paths. This risks pulling in system OpenSSL headers instead.
For almost every BoringSSL header, the first #include is base.h, which
does not exist upstream, thus the mistake will be caught.
The exception is base.h itself which naturally does not include itself.
Have it include an empty is_boringssl.h header to catch this mistake.

The FIPS RSA generation algorithm is unkind to keys with funny bit
sizes. Odd numbers of bits are especially inconvenient, but the sqrt(2)
bound is much simpler if the key size is a multiple of 128 (thus giving
prime sizes a multiple of 64, so the sqrt(2) bound is easier to work
with).
Also impose a minimum RSA key size. 255-bit RSA is far too small as it
is and gives small enough primes that the p-q FIPS bound (2^(n/2-100))
starts risking underflow.

As a precursor to removing the code entirely later, disable the protocol

This change also makes SSLv3_method *not* enable SSL 3.0. Normally
version-specific methods set the minimum and maximum version to their
version. SSLv3_method leaves the minimum at the default, so we will
treat it as all versions disabled. To help debugging, the error code is
switched from WRONG_SSL_VERSION to a new NO_SUPPORTED_VERSIONS_ENABLED.
This also defines OPENSSL_NO_SSL3 and OPENSSL_NO_SSL3_METHOD to kick in
any no-ssl3 build paths in consumers which should provide a convenient
hook for any upstreaming changes that may be needed. (OPENSSL_NO_SSL3
existed in older versions of OpenSSL, so in principle one may encounter
an OpenSSL with the same settings.)

- clang emits callq instead of call.
- clang emits .cfi_endproc after .size for the dummy functions. This

Alas, clang seems to compile the DEFINE_METHOD_FUNCTION hooks in a way
that brings the .rel.ro back AND isn't honoring the noinline. We'll

For now, this is disabled by default on the verifying side but may be
