The deinterlace hotkey now turns of/off deinterlacing.

At the core and vout, you now have 2 variables:
 - deinterlace: on/off/auto (off is default). It let you say if you
 want to deinterlace or not.
 - deinterlace-mode: discard, blend, ... (blend is default). It let you
 specify the mode used when deinterlacing is equal to on/auto.

 The mode auto is not yet supported and simply default to on.

It will allow using "deinterlace-mode" as a core option.

Only the RC interface still used it, and it was not really needed
(net_Accept() returns -1 when the object is killed).

This saves all third party LibVLC application from having to set it
(The library depending on VLC configuration was really lame IMHO).

This avoids getting a totally misplaced controller if the resolution
is larger than in previous runs, or if the multi-screen layout was
changed.

The output timestamp/length wasn't set anymore.

It will allow to
 - have a working simple preference in GUI
 - specify it in playlist (safe).
 - have an "auto" mode.

There is 2 new deinterlacing modes: "Yadif" and "Yadif (2x)".
"Yadif (2x)" doubles the frame rate, whereas "Yadif" throws away one field.

yadif.h comes from vf_yadif.c (GPLv2+) from MPayer project. I have stripped it
a bit but let the functions unmodified for easier maintainance.

We simply make sure the buffer is big enough, instead of trying (and
failing) to guess the biggest possible size.

List all standards and not standard groups.
Fix debug output.

The data offset was wrong (at each chunk).

It does change the timestamp of the audio buffer after a discontinuity.
