Martin Storsjö e1d0b3d875 srtp: Add support for a few DTLS-SRTP related crypto suites 
The main difference to the existing suites from RFC 4568 is
that the version with a 32 bit HMAC still uses 80 bit HMAC
for RTCP packets.

Martin Storsjö ab2ad8bd56 lavf: Add functions for SRTP decryption/encryption 
This supports the AES_CM_128_HMAC_SHA1_80 and
AES_CM_128_HMAC_SHA1_32 cipher suites (from RFC 4568) at the
moment. The main missing features are replay protection (which can be
added later without changing the internal API), and the F8 and null
ciphers.
