fc792308c5 srtp: Include rtpdec.h for RTP_MAX_PACKET_LENGTH
This was missed from 350ad50b - this fixes building the fate-srtp
test.

b4bb1d493c srtp: Don't require more input data than what actually is needed
The theoretical minimum for a (not totally well formed) RTCP packet
is 8 bytes, so we shouldn't require 12 bytes as minimum input.

Also return AVERROR_INVALIDDATA instead of 0 if something that is
not a proper packet is given.

a2a991b2dd srtp: Improve the minimum encryption buffer size check
This clarifies where the limit number comes from, and only
requires exactly as much padding space as will be needed.

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.

This squelches false positive warnings (with gcc) about them being
used uninitalized.

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.
