this worked out of pure luck for the past 6 years

Drop audio rather than abort.

The latency needs to be returned also when not (yet) running to start
playback on time (the audio output core inserts zeroes accordingly).

Also, then there is no point to using PCM status, as only one single
parameter is used. This simplifies the code and works around a bug
(probably in ALSA plugin framework) whereby delay was always zero
when using the ALSA<->PulseAudio I/O plugin.

Taking any lock in vlc_testcancel() is prone to deadlock since it gets
called from vlc_cond_(timed)wait() with the mutex held.

Not using semaphores at all would probably be saner here though.

The core takes care of it now. In principles.

 - Set the flag when the buffer is marked.
 - Set the flag (for next buffer) when the buffer is dropped.
 - Clear the flag when a buffer is played.

The filters chain will convert to whatever output format is needed, so
this was redundant.

This uses the old 0.12 buildsystem with regex.* from glibc 2.2.5
and uses LGPL

Re-license almost all the playback modules to LGPLv2.1+ with
authorization from their respective contributors (230+)

This includes:
 - access, codec, packetizers, demux
 - audio filters, audio mixers, audio output
 - video filters, video chroma, video output
 - text renderers
 - XML parser
 - ARM NEON and SSE2 optimisations (mostly for chromas and filters)

Some modules are not concerned:
 - BDA and DShow access modules because Manol Manolov is AWOL
 - Real RTSP, because it is derived from Xine
 - x264 and t140 because they are encoders only
 - DLL Loader, because it is derived from MPlayer
 - DTS packetizer, because Jon Lech Johansen is AWOL
 - Shine and WMAfixed, because they are derived from Rockbox
 - Real demuxer, as it is derived from MPlayer and Wang Bo is AWOL
 - MPC demuxer, as Yavor Doganov is AWOL
 - Tivo demuxer, because it is derived from an MPlayer fork
 - Playlist demuxer, (WPL and ZPL parts missing), because suheaven is AWOL
 - iOS audio output and video display, because author refuses the license change
 - Equalizer and compressor, because Ronald Wright is AWOL
 - Mono, Headphone and Dolby, because author refuses the license change
 - hqdn3d and yadif, because they are from MPlayer/libavfilter
 - remoteosd, because it derives from RealVNC code
 - MMX optimisations, because Ollie Lho, from SiS, is AWOL
 - Rotate, because it depends on GPL motion

Nota Bene:
 - Some modules depend on GPL-only libraries, a LGPL module does not mean
   that the resulting binary module will be LGPL.
   Libraries affected would include liba52, libdvdcss, libdvdnav, libdvdread,
   faad2, libdca, libmad, libmpeg2, libpostproc, SRC, sid, zvbi and probably others.

new vlc_path2uri function now expects a valid not-yet-converted file name.

This fixes art display errors with latest vlc from current git rep.
