We deal with the difference between binary and text modes on Windows by
doing all I/O in binary mode (including, in particular,
stdin/stdout/stderr) and by treating text mode as equivalent to binary
mode (i.e. we use Unix line ending semantics).

In an attempt to assign a zero-length HMAC key, consumers might
incorrectly call:
HMAC_Init_ex(key=NULL, key_len=0)
This does not work as expected since |key==NULL| has special semantics.
This bug may consequently result in uninitialized memory being used for
the HMAC key data.
This workaround doesn't fix all the problems associated with this
pattern, however by defaulting to a zero key the results are more
predictable than before.

They're not in the duplicated handshake state machines anyway. But we still
shouldn't negotiate them. d1_pkt.c assumes Finished is the only post-CCS
handshake message. An unexpected handshake message in the current epoch may
either be a retransmit/out-of-order message from the previous handshake, or a
message from the next handshake (also potentially out-of-order). In the former
case, we shouldn't spin up another handshake state machine instance.
(This assumption is required due to a protocol bug. DTLS resets sequence
numbers after a handshake, so it is necessary to categorize handshake fragments
by pre-CCS and post-CCS to distinguish between retransmit and renego.)

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.
