POSIX does not document the == construction for test; Even if GNU test and bash builtin allow it, configure is run by sh and FreeBSD test does not allow it so that this test is always false there.

macosx: Renamed 'Quick Open File' to 'Open File' and 'Open File' to 'Advanced Open File' and switched the menu order accordingly to provide the same names as the Qt4 intf

Improve spectrum visualization. Change options : the number of bands for the spectrum and spectrometer visualization is now set with a boolean. Ban some actions to avoid segfaults in visualizations.

The original idea and debug come from basos g patch with the following
comment:

"A dead lock was created when adding an spu filter (like marq)
because the same mutex was used for spu->p stuff and sub filter
chain (p_spu->p->p_chain)."

 I implemented the creation/destruction of the chain outside the sub-filter
callback.

Added a comment to describe inheritable variables
Added debug messages to get clues about variable

Also partially (internally only) fix missing Win64 drawable bits

If multiple video ouputs exist, only one will now use the drawable.
This still does not implement drawable size, window type and probably
Win64 support properly.

Also, this is not currently used by libvlc_media_player_set_drawable
although it probably should. This function looks pretty weirdly -to
stay polite- implemented.
