ed71e262b0 srtpdec: do not warning old replay errors
Reordered packets producing decrypting errors are very normal,
so we should filter which errors are warning and which not.

b2d0795185 srtp: Add support for GCM (RFC 7714)
The GCM support in libsrtp have been there for a while and
it can be useful for some applications.

Fixes https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/issues/913

srtpdec: Lower severity of srtp_err_status_replay_fail
AFAIU this happens when encountering retransmissions. Don't print a
warning for these packets.

e9aa117200 srtp: Support libsrtp2
For libsrtp 1, add defines that translate the new namespaced identifiers
to the old unnamespaced ones. Also move the code for setting and getting
a stream's ROC into two compat functions that match libsrtp2's API.

It seems that libsrtp2 properly supports changing the ROC without having
to touch the sequence numbers afterwards, given that srtp_set_stream_roc
sets a pending_roc field, so the entire roc_changed dance should not be
needed anymore. The compat functions for libsrtp 1 just contain our
preexisting hacks, however, so it's still needed there.

libsrtp2 has no means of discovering the streams in the session, so to
create the stats structure we need to iterate over our own set of SSRCs.
For this we also need to re-add the previously removed ssrcs_set to the
encoder.

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.
