Fork-unsafe buffering was a mode that could be enabled by applications
that were sure that they didn't need to worry about state duplication.
It saved reads to urandom.
Since everything is now going through the CTR-DRBG, we can get the same
effect by simply not reading additional data from urandom in this case.
This change drops the buffering from urandom.c and, instead, implements
fork-unsafe buffering as a mode that skips reading additional data from
urandom, which only happened when RDRAND wasn't available anyway.
Since we expect the power-on self-tests to call into the PRNG, this
change also makes the flag capable of changing at any point by using a
mutex rather than a once. This is split into a separate file so that it
doesn't have to go into the FIPS module—since it uses r/w data that
would be a pain.

- We mass-invalidated every serialized client session in

filling in key_exchange_info on the client.
- Server sessions were not mass-invalidated, but static RSA
key_exchange_info never worked on the server.

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.

This change drops this step. Instead, inject-hash.go parses the object

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.
