* Add right-click "info" item in qt4 playlist

The scheme I used sucked big times.

- move vlm to input/
- remove unused libvlc export

Compile glx plugin only if all required headers are present

* libvlc sources and plugins now define __LIBVLC__ and headers exported to
  plugins (ie, include/vlc_*.h) check for this
* libvlc sources use the value of the "libvlc" component in vlc-config instead
  of vlc
* Apply flags directly to "libvlc" in configure.ac - might temporarily break win32 :)

* use the current x264 revisions and Xcode's native nasm on x86-OSX. This requires Xcode 2.4.1 or later. Patch by Brian Raymond <braymond --a-t- echostorm net>

I second his request to include this in 0.8.6 as well, since this update improves the performance on PowerPC-based Macs by 20% without breaking compatibility with our module.

- Remove opening and closing quote when unescaping

* Implement MRL handling for file, disc and network
* Moved input slave option to the global dialog (not file specific and
  avoid cluttering the file subpanel)
* Initial implementation of the network panel based on ideas and work by
  Leo Spalteholz. Thanks !
* Improve layouting and handling of the advanced options subpanel

- Do not validate quotes recursively (there is no reason to do that)
  and it is really unlike anything else.
- Do not allow escaping non-ASCII (to avoid UTF-8 breakages)
  or non-printable characters.
[1] we don't support every features of C escaping though

It reads like some sort of English now, though it could be further improved.

  fixes a big crasher in the DestroyFilter of the logo video filter

It made little sense to have an header that can only be included
in a single file.
Re-use libvlc.h for generic libvlc internal declarations.

This help suppress dependency of src/misc/modules.c
upon some structs typedefs just for the sake of sizeof.

Control & Playback buttons have the same size

* Don't immediatly overwrite our driver retrieved video palette value with 0.

* microDVD should use the framerate of the movie if that is known, before falling back to 25fps

vlc.win32.nsi.in: Add shortcut for Direct3D with no hardware acceleration. YUV->RGB hardware accelaration should normally be enabled except on some buggy NVidia cards/drivers?
