1. Added the usual cipher suite changes for the new suite.
2. Added a build option, WOLFSSL_ALT_TEST_STRINGS, for testing
against GnuTLS. It wants to receive strings with newlines.
3. Updated the test configs for the new suite.
Tested against GnuTLS's client and server using the options:
$ gnutls-cli --priority "NONE:+VERS-TLS-ALL:+AEAD:+ECDHE-ECDSA:+AES-128-CCM:+SIGN-ALL:+COMP-NULL:+CURVE-ALL:+CTYPE-X509" --x509cafile=./certs/server-ecc.pem --no-ca-verification -p 11111 localhost
$ gnutls-serv --echo --x509keyfile=./certs/ecc-key.pem --x509certfile=./certs/server-ecc.pem --port=11111 -a --priority "NONE:+VERS-TLS-ALL:+AEAD:+ECDHE-ECDSA:+AES-128-CCM:+SIGN-ALL:+COMP-NULL:+CURVE-ALL:+CTYPE-X509"
To talk to GnuTLS, wolfSSL also needed the supported curves option
enabled.
1. fixed the AES-CCM-16 suites
2. added DHE-PSK as a key-exchange algorithm type
3. Added infrastructure for new suites:
* TLS_DHE_PSK_WITH_AES_128_GCM_SHA256
* TLS_DHE_PSK_WITH_AES_256_GCM_SHA384
* TLS_DHE_PSK_WITH_AES_128_CBC_SHA256
* TLS_DHE_PSK_WITH_AES_256_CBC_SHA384
* TLS_DHE_PSK_WITH_NULL_SHA256
* TLS_DHE_PSK_WITH_NULL_SHA384
* TLS_DHE_PSK_WITH_AES_128_CCM
* TLS_DHE_PSK_WITH_AES_256_CCM
4. added test cases for new suites
5. set DHE parameters on test server when using PSK and a custom cipher
suite list
6. updated half premaster key size
