RT#3592 provides an instance where the OPENSSL_assert that this commit
replaces can be hit. I was able to recreate this issue by forcing the
underlying BIO to misbehave and come back with very small mtu values. This
happens the second time around the while loop after we have detected that the
MTU has been exceeded following the call to dtls1_write_bytes.

Previously, state variant was not advanced, which resulted in state
being stuck in the st1 variant (usually "_A").
This broke certificate callback retry logic when accepting connections
that were using SSLv2 ClientHello (hence reusing the message), because
their state never advanced to SSL3_ST_SR_CLNT_HELLO_C variant required
for the retry code path.

The current documentation contains a bunch of spelling and grammar mistakes. I also
found it hard to understand some paragraphs, so here is my attempt to improve its
readability.

When we're configured with no-ssl3 and we receive an SSL v3 Client Hello, we set
the method to NULL. We didn't used to do that, and it breaks things. This is a
regression introduced in 62f45cc27d. Keep the old
method since the code is not able to deal with a NULL method at this time.
