The Quartztext module needs a rewrite. All other parts of VLC are working nicely in 64bit mode.

Conflicts:

	modules/access/qtcapture.m

 There will be some regressions, I used automatic sed replacement with manual
checks but there was a lot to change.
 It's only the first pass.

Those multi-lines are still to be done (it's going to be fun...)

- Hopefully also fixes PAR and usage of older iSights (different fourcc)
- Note that the iSight reports itself as a 320x240 (NOT 640x480) device by default.
(cherry picked from commit ef585031b4c58db3cc333a96c6cbb6c07d85f8b5)

Fixes a crash in Close() of the module.

This reverts commit b65ca27b.

It doesn't work well enough.

qtcapture: Don't release objects when libvlc quit, else we may loose our main thread, and dead lock.

Don't send blocks from qtcapture Demux that we have already sent before. Avoid excessive CPU usage while there are no new blocks.

This works, but perhaps i'm loosing too much precission here. Are there better ways to change timevalue + scale into walltime ?

Clean up the code a bit, turning to be half as laggy as the previous code, but it will need to be properly fixed.

Additionally, we are a good citizen now, since we actually quit our session instead of just releasing it. This takes a couple of secs though.

qtcapture: Tab fixes, plus attempt to get the real PTS. We still really do lag compared to PhotoBooth...

qtcapture: New access_demux module (QTKit based) to capture video from your iSight Camera on Mac OS X.

Usage: 'vlc qtcapture://'.

This is a 2 hours hacked module. We don't grab sound yet, and there are a lot of FIXME.

Note: For some reason QTKit needs a the main thread to be a cocoa thread. Don't expect it to run with -I dummy for instance.
