* Remove NTRU and OQS
* Keep the DTLS serialization format backwards compatible.
* Remove n from mygetopt_long() call.
* Fix over-zealous deletion.

* Improvements to the notBefore and notAfter date handling.
* Improvements to BIO and BIO_METHOD
- Moved structure to public area to allow for dereferencing
- Renamed members to provide compatibility.
- Added support for custom BIO methods for read/write.
* Added advanced openssl compatibility test cases for key and certificate generation.
* Fix for `ASN1_STRING_set` to allow NULL data.
* Fix to populate public key information on `EVP_PKEY_assign_RSA` and `EVP_PKEY_assign_EC_KEY`.
* Fix naming for `X509_get_notBefore` and `X509_get_notAfter` functions.
* Added `wc_EccPublicKeyDerSize`.
* Improvements to `wc_RsaPublicKeyDerSize`, so dummy memory doesn't have to be allocated.
* Made the `wc_*PublicKeyDerSize` functions public.
* Eliminate use of snprintf for UTC to generalized time conversion in `wolfSSL_ASN1_TIME_to_generalizedtime`.
wolfSSL remains agnostic to network socket behavior be it blocking or non-blocking. The non-blocking flag was meant for the default EmbedRecvFrom() callback for use with UDP to assist the timing of the handshake.
1. Deprecate wolfSSL_set_using_nonblock() and wolfSSL_get_using_nonblock() for use with TLS sockets. They become don't-cares when used with TLS sessions.
2. Added functions wolfSSL_dtls_set_using_nonblock() and wolfSSL_dtls_get_using_nonblock().
3. Removed a test case from EmbedReceive() that only applied to UDP.
4. Removed the checks for non-blocking sockets from EmbedReceive().
5. Socket timeouts only apply to DTLS sessions.
* More cleanup to move PEM functions from ssl.c to asn.c (`wolfSSL_CertPemToDer`, `wolfSSL_KeyPemToDer`, `wolfSSL_PubKeyPemToDer`). Renamed these API's to `wc_` and added backwards compatability macro for old function names.
