Added TLS 1.3 testing.
Added Ed25519 and Ed448 testing.
Added tesitng of OpenSSL client against wolfSSL server.
Fixed builds of Curve25519/Curve448/Ed25519/Ed448 in different
configurations.
* Added ECC and RSA intermediate CA's and server/client chain certificates for testing.
* Enhanced suites test to support expected fail arg `-H exitWithRet` in any test .conf file.
* Added new `test-altchains.conf` for testing with `WOLFSSL_ALT_CERT_CHAINS` defined.
* Added new `test-chains` for testing chains.
* Added new `test-dhprime.conf` for DH prime check tests.
* Added new `test-trustedpeer.conf` for testing `WOLFSSL_TRUST_PEER_CERT`.
* Refactor to add `-2` to disable DH prime check by default (except for new test-dhprime.conf).
* Added ability to run a specific test.conf file using syntax like `./tests/unit.test tests/test-altchains.conf`.
1. Modify all the test configuration files to disable the DHE prime test.
2. Add a test configuration that tests three cipher suites with the DHE prime test enabled.
* Added test for certificate with bad alt name containing a null character mid byte stream.
* Fix for issue with suites unit test where last arg in file doesn't conain data for a param, causing it to skip test.
* Fix for last test in tests/test.conf not being run for `TLSv1.2 RSA 3072-bit DH 3072-bit`.
* Moved the `tls-cert-fail.test` tests into the new expected failure suite test (`./tests/test-fails.conf`). Now it explicilty checks RSA and ECC for the no signer and no sig tests.
