This regressed in e95d20dcb8. EVP_AEAD will push
errors on the error queue (unlike the EVP_CIPHER codepath which checked
everything internally to ssl/ and didn't bother pushing anything). This meant
that a dropped packet would leave junk in the error queue.
Later, when SSL_read returns <= 0 (EOF or EWOULDBLOCK), the non-empty error
queue check in SSL_get_error kicks in and SSL_read looks to have failed.

BoringSSL currently retransmits non-deterministically on an internal timer
(rather than one supplied externally), so the tests currently fail flakily
depending on timing. Valgrind is a common source for this. We still assume an
in-order and reliable channel, but drop retransmits silently:
- Handshake messages may arrive with old sequence numbers.
- Retransmitted CCS records arrive from the previous epoch.
- We may receive a retransmitted Finished after we believe the handshake has
completed. (Aside: even in a real implementation, only Finished is possible
here. Even with out-of-order delivery, retransmitted or reordered messages
earlier in the handshake come in under a different epoch.)
Note that because DTLS renego and a Finished retransmit are ambiguous at the
record layer[*], this precludes us writing tests for DTLS renego. But DTLS
renego should get removed anyway. As BoringSSL currently implements renego,
this ambiguity is also a source of complexity in the real implementation. (See
the SSL3_MT_FINISHED check in dtls1_read_bytes.)
[*] As a further fun aside, it's also complex if dispatching renego vs Finished
after handshake message reassembly. The spec doesn't directly say the sequence
number is reset across renegos, but it says "The first message each side
transmits in /each/ handshake always has message_seq = 0". This means that such
an implementation needs the handshake message reassembly logic be aware that a
Finished fragment with high sequence number is NOT an out-of-order fragment for
the next handshake.
