libvlc: Add a --ignore-config options that allow not to use the config file. This is especially useful for libvlc based applications.

Move lua{intf,playlist,meta} to lua/{intf,playlist,meta}. I haven't been able to check the changes to the Win32 and Mac OS X specific Makefile.am parts.

Revert 4ce6c3f3. Fixes drag and drop on my system. Adding quotes to a filename in C/C++ isn't going to change anything (it would on a command line given the way getopt works). Tested with a file named "/home/dionoea/media/test test/redefined :ni=ntendo.mpg".

Bug spotted by Anthony Loiseau

This fixes bbf6e4fe. Apologize to funman II.

playlist: rename ML_decref() to recursively_decref(). Please give useful name to function saying what they do.

playlist: Correctly indicate why we put a buggy yield() at this place. And document a bit that nasty recusrsive ML_Decref() function.

This comes with my official excuses to funman.

Please TEST your changes before pushing
At least, READ the code instead of modifying it blindly

playlist: To avoid race on p_input destruction, keep a reference around while we need it in playlist_MLLoad().

playlist: Proper locking when editing playlist variable in loadsave.c. Also correctly release p_ml_onelevel->p_input and p_ml_category->p_input when changing them.

This fixes partly make check and input items leaks.

There is no need to copy the files in that case thanks to VPATH.
That assumes you are using a source tarball then - if not, you are
screwed anywhow.
