1. Separated the peer ID from the array index into the peer sequence
list. This allows peer IDs to range from 0..255, and to have an
arbitrary size for the sequence list.
2. Add API to add and remove peer IDs from the sequence number list.
1. Added new cipher suite for use with Multicast DTLS,
WDM_WITH_NULL_SHA256. (It should be a private suite.)
2. Update the API test to use the new suite.
1. Add DTLS-multicast to the enable options.
2. Reorg DTLS related enable options together.
3. Update a couple enable option texts to use the AS_HELP_STRING() macro.
4. Add three new APIs for managing a DTLS Multicast session.
5. Add test code for new APIs.
6. Add stub code for the new APIs.
Reset list of supported sig algorithms before sending certificate
request on server.
Refactored setting of ticket for both TLS13 and earlier.
Remember the type of key for deciding which sig alg to use with TLS13
CertificateVerify.
RSA PKCS #1.5 not allowed in TLS13 for CertificateVerify.
Remove all remaining DTLS code as spec barely started.
Turn off SHA512 code where decision based on cipher suite hash.
Fix fragment handling to work with encrypted messages.
Test public APIS.
TLSX support for the extention and treating it like the Signature
and Hash algorithms extension. It is to be enabled by default and
the user can turn it off at run time or build time.
1. Update the example client and server to test DTLS-SCTP.
2. Modify the test.h functions for setting up connections to allow
for a SCTP option.
3. Update other examples to use the new test.h functions.
4. Removed some prototypes in the client header file were some functions
that should have been static to the client.c file and made them static.
