Make DTLS and protocol demux default (now use #defines to switch it off):
DSRV_NO_DTLS will switch off DTLS functionality.
DSRV_NO_PROTOCOL_DEMUX will switch off protocol demultiplexing.

Show protocol demux for DTLS in tests/dtls-test.c.
Do not need special Makefile.dtls any more.
More protocol demultiplexing.
Send Hello Verify manually to avoid status creation before cookie exchange is complete.
Conditionals for DTLS and multiprotocol stuff
Cookie generation/verification is now in dtls.c
