15a3b0f6ce srtpenc: remove get-rollover-counter signal and add stats property
We remove get-rollover-counter signal in favor of the "stats"
property. The "stats" property is a GstStructure with caps
application/x-srtp-encoder-stats that contains an array of
structures with caps application/x-srtp-stream.
Each stream structure contains "ssrc" and "roc" fields.

73ebdb888e srtpdec: also check for "roc" in caps
Currently, gst_srtp_dec_sink_setcaps is happy if the "roc" field is not
provided in the caps. If it is not provided the stream will be properly
inserted in the hash table with a default "roc". Then, when the first
buffer arrives validate_buffer will find an existing stream in the hash
table and will not signal request-key, not allowing the user to provide
a "roc".

This patch expects "roc" in gst_srtp_dec_sink_setcaps, if not found a
request-key will be signaled and the user will be able to provide all
the srtp fields, including "roc".

88f85f6595 Revert "srtpdec: Add support for buffer list"
This reverts commit ff11a1a8a0.

It can't be assumed that all buffers in a buffer list have the same SSRC or
are RTP or RTCP only. It has to be checked for every single buffer, and one
basically has to do the processing that is done by the default chain_list
implementation.

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.

rtcp_buffer_get_ssrc is called even with RTP buffers. this means we

and thus hit GST_RTCP_TYPE_INVALID. we now take care of this.

* 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.
