Revise DTLS code. There was a *lot* of code duplication in the
DTLS code that generates records. This makes it harder to maintain and
sometimes a TLS update is omitted by accident from the DTLS code.
Specifically almost all of the record generation functions have code like
this:
some_pointer = buffer + HANDSHAKE_HEADER_LENGTH;
... Record creation stuff ...
set_handshake_header(ssl, SSL_MT_SOMETHING, message_len);
...
write_handshake_message(ssl);
Where the "Record creation stuff" is identical between SSL/TLS and DTLS or
in some cases has very minor differences.
By adding a few fields to SSL3_ENC to include the header length, some flags
and function pointers for handshake header setting and handshake writing the
code can cope with both cases.

- EC_GROUP_cmp shouldn't consider curves equal just because
the curve name is the same. (They really *should* be the same
in this case, but there's an EC_GROUP_set_curve_name API,
which could be misused.)
- EC_POINT_cmp shouldn't return 0 for ERR_R_SHOULD_NOT_HAVE_BEEN_CALLED
or EC_R_INCOMPATIBLE_OBJECTS errors because in a cmp API, 0 indicates
equality (not an error).

When verifying a partial path always check to see if the EE certificate
is explicitly trusted: the path could contain other untrusted certificates.

This fix ensures that
* A HelloRequest is retransmitted if not responded by a ClientHello
* The HelloRequest "consumes" the sequence number 0. The subsequent
ServerHello uses the sequence number 1.
* The client also expects the sequence number of the ServerHello to
be 1 if a HelloRequest was received earlier.
This patch fixes the RFC violation.

If no new reason codes are obtained after checking a CRL exit with an
error to avoid repeatedly checking the same CRL.
This will only happen if verify errors such as invalid CRL scope are
overridden in a callback.
