9c00d261c3 srt: preserve ABI compatibility
Reintroduce socket descriptor parameter removed in 327ad84e to
"caller-added" and "caller-removed" signals, just set it always to zero.

327ad84e35 srt: don't pass SRT socket ID to "caller-added,removed" signals
The caller's IP and port is enough for unique identification. Don't leak
the socket handle since using it in unadvised libsrt calls from the
application could break the SRT element.

4a58af4352 srtobject: add caller address to stats structure
In listener mode, gst_stats() returns an independent set of
statistics for every connected caller. Having the caller's IP and port
present in each structure allows to correlate the statistics with a
particular caller that has been announced by "caller-added" signal.

4e7f7871db srt: Define options added in later revisions
Allows compiling the plugin against old headers.

For SRTO_BINDTODEVICE there's nothing we can do, since the value depends on
configuration options of the library. Nice.

Fixes build with libsrt < 1.4.2

6c35222973 srtobject: distinguish authentication error messages

related to SRT authentication (e.g. incorrect or missing password) so
that the application can recognize them more easily.

ef118f3d0a srtobject: detect socket errors from srt_epoll_wait()
On an error event, epoll wait puts the failed socket in both readfds and
writefds. We can take advantage of this and avoid explicitly checking
socket state before every read or write attempt.

In addition, srt_getrejectreason() will give us more detailed
description of the connection failure.

dd11e91c3b srtsrc: Fix timestamping
SRT provides the original timestamp of a packet (with drift/skew corrected for
local clock), which is what should be used for timestamping the outgoing
buffers. This ensures that we output the packets with the same timestamp (and by
extension rate) as the original feed.

Also detect if packets were dropped (by checking the sequence number) and
properly set DISCONT flag on the outgoing buffer.

Finally answer the latency queries
