We really don't support them anyway

This removes some friends attribute. Can't be a bad thing.

This is a special request for Laurent ;)

This is consistent with libvlc_video_set_parent being deprecated.

It only works -properly- if there is only one video output. This is no
worse than earlier releases.

macosx: updated used Cocoa methods to the current definitions and fixed a few logic errors, which only occur in 64 bit mode

Additionally, disabled ASM optimisations on Darwin 10 for libtheora and switched the default SDK to 10.5 to turn potential 64bit builds more compatible

It closes #2471
It changes a bit the public API but cannot(?) be avoided.

The window provider can take care of this (tested with Qt4 and XCB
window). X11 forwards unhandled events to ancestor windows.

It kinda suck to have to duplicate this though. Qt4 embedded X video
exhibits the same problem. One ugly "fix" could involve the video
output listening for the parent window event - not sure if this would
work. Another option would be to now create a window in the video
output at all, but then we loose reparenting (useless?). In either
cases, handling of hotkeys in fullscreen mode would seem problematic,
unless we handle fullscreen via the window provider too
(control request?).

This reverts commit 0bed6fc3.

It is broken (at least for ps).

Check the content of the file to validate the extension selection.

 Some checks are light but either the file format does not provide enough
identifier data or too much code would be needed. But it is better than
nothing.

Among them, it will now refuse to load file larger than 500Mbytes.
