A previous change in BoringSSL renamed ERR_print_errors_fp to
BIO_print_errors_fp as part of refactoring the code to improve the
layering of modules within BoringSSL. Rename it back for better
compatibility with code that was using the function under the original
name. Move its definition back to crypto/err using an implementation
that avoids depending on crypto/bio.

Avoiding superflous references to RC4 makes it easier to audit the code

These are the remaining untested cipher suites. Rather than add support in

but nothing enables aNULL (all occurrences disable it), and all occurrences of
["ALL:] seem to be either unused or explicitly disable anonymous ciphers.

After sharding the session cache for fallbacks, the numbers have been pretty
good; 0.03% on dev and 0.02% on canary. Stable is at 0.06% but does not have
the sharded session cache. Before sharding, stable, beta, and dev had been
fairly closely aligned. Between 0.03% being low and the fallback saving us in
all but extremely contrived cases, I think this should be fairly safe.
Add tests for both the cipher suite and protocol version mismatch checks.

This conceivably has a use, but NSS doesn't do this buffer either and it still
suffers from the same problems as the other uses of record_pqueue. This removes
the last use of record_pqueue. It also opens the door to removing pqueue
altogether as it isn't the right data structure for either of the remaining
uses either. (It's not clear it was right for record_pqueue either, but I don't
feel like digging into this code.)

It was only ever enabled for handshake and alert messages. The comments cite
renego as a use case though even then I'm not clear on why. The only use I see
is if, say, the Finished message and ClientKeyExchange came in out-of-order.
DTLS is unreliable so leaning on retransmit seems fine, and usually flights
will be packed into one packet where possible. NSS doesn't have any such
buffer and doesn't seem to have problems.
The buffering mechanism is also rather dubious. It stows away the entire packet
and read buffer---all 16K of it---and there may have been other records in that
packet.

Separate actually writing the fragment to the network from assembling it so
there is no need for is_fragment. record_split_done also needn't be a global;
as of 7fdeaf1101, it is always reset to 0 whether
or not SSL3_WANT_WRITE occurred, despite the comment.
I believe this is sound, but the pre-7fdeaf1 logic wasn't quiiite right;
ssl3_write_pending allows a retry to supply *additional* data, so not all
plaintext had been commited to before the IV was randomized. We could fix this
by tracking how many bytes were committed to the last time we fragmented, but
this is purely an optimization and doesn't seem worth the complexity.
This also fixes the alignment computation in the record-splitting case. The
extra byte was wrong, as demonstrated by the assert.

sensitive to the various failure cases. Normalize it all to 0/1 for simplicity.
This does carry a slight risk: any new ctrl hooks we import from upstream that,
like EVP_PKEY_CTX_get_rsa_oaep_md, return something other than success/failure
cannot be called directly via EVP_PKEY_CTX_ctrl. They instead need to
internally be routed through a struct like CBS and only called through the
wrappers. To that end, unexport EVP_PKEY_CTX_ctrl and require that callers use
the wrappers. No code in Google uses it directly and, if need be, switching to
the wrapper would be an incredibly upstreamable patch.
