Use pkg-config to check for libmodplug, and check for version >= 0.8, which is needed for some functions like ModPlug_NumSamples(), ModPlug_GetMessage(), ModPlug_NumInstruments(), etc...

The check for presence has already done in configure.ac

It now autodetects the presence of libVA pkg:
It will fail if --enable-libva is defined and it is not present
It will be activated if nothing is specified and libVA pkg is present

Moreover, it will check the presence of the avcodec/libva.h

You cannot check HAVE_AVCODEC_VAAPI before including "avcodec.h"

This patch also takes into account opening a new skins at any time
(not just at initialization)

When refreshing a window area, the window mask must first be stripped of this
 area, because the new refresh may not result in the same mask being applied.

This patch corrects the following issues :
- an animated bitmap with transparency varying from one subimage to the next
  is now guaranteed the previous subimage won't leave any trace.
- a control that becomes invisible now means transparency is restored
 if no other controls exist for the same area (instead of an undefined and visually unpleasant area)

It is a dead-born codec

We don't want to release the resources associated to the media player, unless user specify it.

And a debug code.

This will download the free to use original recreation of french
channels logo by Cyril Bourreau.

Note, we can mirror them eventually. (Explicit authorization from the
author).

"filename.lua"
  will check if the file name respects the following form:
    "Show.Name S19E01-jde.DEf.avi"
  upon success, it will fill the show name, the episode number and
  season number in the meta data.
  It will also set the title to "Show Name S19E01"

This reverts commit 281d4f3a.

Please discuss those bugs with me before reverting. If you really need, use -I oldrc instead of this non constructive disabling of new code we desperately need people to test.

This reverts commit 4e77528c.

Lua http doesn't poll at all.

This requires one more thread :( but at least people won't report bug
about VLC leaving a defunct child process... Even though I doubt it
would have been a real problem.

Fix 9a00da44

LUA http is bugggy and polls the system every second.

LUA RC is buggy and polls the system every second.
