adcf3f48a5 srtp: Allow getting ssrc of more package types than RR and SR 
This allows decrypting reduce size packages. See RFC 5506

9adefac59b srtpenc: fix failure return values from create_session() 
create_session() returns an err_status_t with
err_status_ok=0 and err_status_fail=1, so
returning TRUE/FALSE is not quite right.

dafa11b9d2 srtpdec: Make sure to send caps events downstream before any segment events 
Upstream might not give us a caps event (dtlssrtpdec) because it might be an
RTP/RTCP mixed stream, but we split the two streams anyway and should report
proper caps downstream if possible.

Fixes "sticky event misordering" warnings with dtlssrtpdec.

da30669589 srtp: add support for rollover counters and replay protection window size 
We add a new signal, get-rollover-counter, to the SRTP encoder. Given a
ssrc the signal will return the currently internal SRTP rollover counter
for the given stream.

For the SRTP decoder we have a new SRTP caps parameter "roc" that needs
to be set when a new SRTP stream is created for a given SSRC.

01c15547d4 srtpdec: fix assertion checking ssrc from rtcp packets 
rtcp_buffer_get_ssrc is called even with RTP buffers. this means we
might end up with an exception and not find any valid RTCP packet type
and thus hit GST_RTCP_TYPE_INVALID. we now take care of this.

fefd021ee2 srtp: add 256-bit key support 
* ext/srtp/gstsrtp.[ch]: added GST_SRTP_CIPHER_AES_256_ICM to
  GstSrtpCipherType and new function cipher_key_size.

* ext/srtp/gstsrtpenc.c: maximum key size is now 46 characters (14 for
  the salt plus the key). If different ciphers are chosen for RTP and
  RTCP the maximum needed key size is expected.

* ext/srtp/gstsrtpdec.c: minor documentation updates.
