* Added new `wolfSSL_CTX_load_verify_locations_ex` that supports flags `WOLFSSL_LOAD_FLAG_IGNORE_ERR`, `WOLFSSL_LOAD_FLAG_DATE_ERR_OKAY` and `WOLFSSL_LOAD_FLAG_PEM_CA_ONLY`.
* Fix for `PemToDer` to handle PEM which may include a null terminator in length at end of file length causing wrong error code to be returned. Added test case for this. (ZD 4278)
* Added macro to override default flags for `wolfSSL_CTX_load_verify_locations` using `WOLFSSL_LOAD_VERIFY_DEFAULT_FLAGS`.
* Added tests for loading CA PEM's from directory using `wolfSSL_CTX_load_verify_locations` and `wolfSSL_CTX_load_verify_locations_ex` with flags.
* Added tests for `wolfSSL_CertManagerLoadCABuffer`.
* Updated the expired test certs and added them to `./certs/test/gen-testcerts.sh` script.
In the past, Doxygen just listed API for wolfSSL and wolfCrypt in one long list.
Now there are two separate pages for the wolfSSL and wolfCrypt API references.
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.
* Added PK callback context tests for client/server examples (`SetupPkCallbackContexts`).
* Added new test define for `TEST_PK_PRIVKEY` to allows simulating hardware based private key.
* Added new test.h function for loading PEM key file and converting to DER (`load_key_file`).
* Added way to get private key signature size (`GetPrivateKeySigSize`).
* Added new ECC API `wc_ecc_sig_size_calc` to return max signature size for a key size.
* Added inline comments to help track down handshake message types.
* Cleanup of RSS PSS terminating byte (0xbc) to use enum value.
* Fixed bug with PK callback for `myEccVerify` public key format.
* Fixed bug with PK callback for ED25519 verify key buffer in DoServerKeyExchange.
