The way SRT's async / epoll-based IO works is that the event status is stored
in the epoll containers. That is, if an event occurs on an SRT socket, and that
SRT socket isn't part of any epoll container, then that event is lost. If we
later add that socket to an epoll container, we still won't receive the event
even if it wasn't serviced.
Therefore we create the epoll and put the fd into it right after the connection
is established.

Sometimes there was a confusion between srt_*() function return values and
libavformat-style return values.

- Call srt_epoll_release() to avoid fd leak on libsrt_setup() error.
- Call srt_cleanup() on libsrt_open() failure.
- Fix return value and method on mode parsing failure.

In listener mode the first fd is not closed when libsrt_close() is called
because it is overwritten by the new accept fd. Added the listen_fd to the
context to properly close it when libsrt_close() is called.
Fixes trac ticket #8372.

libsrt changed the:
SRTO_SMOOTHER -> SRTO_CONGESTION
SRTO_STRICTENC -> SRTO_ENFORCEDENCRYPTION
and removed the front of deprecated options (SRTO_SMOOTHER/SRTO_STRICTENC)
in the header, it's lead to build fail

Otherwise the user is not able to override the SRT API connect timeout above 5
sec without also setting the timeout option.

Return os error code if available, check for both SRT_EASYNCRCV and
SRT_EASYNCSND when transforming them to EAGAIN and only display error if it is
not EAGAIN.

After f8990c5f41 we properly set non-blocking
mode which makes the connect() call return always 0 even if no connection can
be established.
Fix this by always doing a poll after calling connect(). Also there was some
leftover copy paste code which checks for various errors which are simply not
possible with SRT.

rw_timeout is the generic URLcontext option, not the protocol specific timeout
option, also ?rw_timeout never worked because ?timeout was parsed instead.

As written in https://github.com/Haivision/srt/blob/v1.4.1/docs/API.md,
the nonblock mode is activated if SRTO_SNDSYN and SRTO_RCVSYN, for
sending and receiving respectively, are set to 0.

add linger parameter to libsrt, it's setting the number of seconds
that the socket waits for unsent data when closing.

SRT API Documentation:
This flag is superfluous if both parties are at least version 1.3.0
(this shall be enforced by setting this value to SRTO_MINVERSION if
you expect that it be true) and therefore support HSv5 handshake,
where the SRT extended handshake is done with the overall handshake
process.
This flag is however obligatory if at least one party may be using
SRT below version 1.3.0 and does not support HSv5.
Several SRT options are missing. Since pkg_config requires libsrt v1.3.0 and above, it should be able to support options added in libsrt v1.3.0 and below.
This commit adds 8 SRT options.
sndbuf, rcvbuf, lossmaxttl, minversion, streamid, smoother, messageapi and transtype
The keys of option are equivalent to stransmit.
