This was probably the worst offender of them all as read_bytes is the wrong
abstraction to begin with. Note this is a slight change in how processing a
record works. Rather than reading one fragment at a time, we process all
fragments in a record and return. The intent here is so that all records are
processed atomically since the connection eventually will not be able to retain
a buffer holding the record.
This loses a ton of (though not quite all yet) those a2b macros.

Alert handling is more-or-less identical across all contexts. Push it down from

shared between TLS and DTLS.
Now the only type mismatch managed by read_bytes is if we get handshake data in

Move this logic out of dtls1_read_bytes and into dtls1_get_record. Only trigger
it when reading from the buffer fails. The other one shouldn't be necessary.
This exists to handle the blocking BIO case when the
BIO_CTRL_DGRAM_SET_NEXT_TIMEOUT signal triggers, so we only need to do it when
timeouts actually trigger.
There also doesn't seem to be a need for most of the machinery. The
BIO_set_flags call seems to be working around a deficiency in the underlying
BIO. There also shouldn't be a need to check the handshake state as there
wouldn't be a timer to restart otherwise.

Operations in the DSA signing algorithm should run in constant time in
order to avoid side channel attacks. A flaw in the OpenSSL DSA
