63ce9fd23c rtmpdh: Use GMP functions directly, instead of nettle wrappers
mpz_import and mpz_export were added in GMP 4.1, in 2002.

This simplifies the DH code by clarifying that it only uses pure
bignum functions, no other parts of nettle/hogweed.

b2f0f37d24 rtmpdh: Generate the whole private exponent using av_get_random_seed() with nettle/gmp
Don't use a PRNG for generating it; that defies the intended use
within the cryptograhic handshake.

acd554c103 RTMPE protocol support
This adds two protocols, but one of them is an internal implementation
detail just used as an abstraction layer/generalization in the code. The
RTMPE protocol implementation uses ffrtmpcrypt:// as an alternative to the
tcp:// protocol. This allows moving most of the lower level logic out
from the higher level generic rtmp code.
