Same problem than in 1d4c5a49

The crappy input buffering code of rc is replaced by the (now) decent
one of telnet. A new telnet transport is relatively cleanly added, and
VLM commands are made available (over any transport). Example of use:

vlc -Irc --rc-host "telnet://localhost:4212"

Only C userdata can set a garbage collector that way. Client sockets
are leaked when the interface is stopped, because the destructor is
never called. And given how the thread is cancelled in poll(), I can't
see a simple way to call it.

poll() revents are flags, and the lua module tests for equality...
Obviously this has been working merely by accident given that a remote
host resetting a connection generates only POLLIN, and neither POLLHUP
nor POLLERR.

lua doesn't support bitwise operators so this is the simplest way.

This is one of the most used function, and thus makes it faster to
activate

Exactly 0 functionnal change here

Contrary to V4L2, dshow does not extract options from the MRL. So there
i effectively no way to set anything via playlist. This allows the
options that more-or-less correspond to MRL options in V4L2.

Parsing the MRL might make more sense than marking options as safe.

Some distros separate libsidplay2 into few packages.
In that case libresid-builder can be absent even if libsidplay2 was found.
Now, if libsidplay2 was found, we check for libresid-builder explicitly.

This is untested. Frequency offsets and diseqc are not done yet.

It seems that DMX_ADD_PID does not work. So revert back to the
non-shared DVR node, unless budget mode is enabled.

This is incomplete and hence not automatically compiled. Conditional
Access, DVB-S and scanning are missing. DVB-T and ATSC are not tested.
DVB-C works.

It is not clear to me what the problem is, but it seems VLC does not
like the Linux DVB kernel demux. Only budget mode seems to work
correctly at the moment.

Too many complaints, notably on Reddit

As an added bonus, we don't need to open /dev/null for nothing.

requires latest contrib package
