This partly fixes #2815, but the conflict of "Reveal in Finder" and "Record" has not yet been fixed.

When using the hotkeys to seek, each offset seek was executed twice. The bahavior of INPUT_CONTROL_SET_TIME_OFFSET has changed, and these callbacks did not account for that yet.

This closes #2820

Just to get compilation working. Any use of Timer API will result in an abort() for now.

This string is already in use, so no problem with stringfreeze for
1.0 (According to xtophe).

In general, we should avoid PL_LOCK'ing around stuff that the Datasource does,
and restrict it to the lines that directly deal with the core playlist.

This should fix #2810

This closes #2814

It allows to use mouse inside a simple "video filter2"
It is not meant to stay.

Unfortunately, the thread stack remains allocated as our threading
abstraction does not support detaching.

It avoid an assert if a program was created after the input was paused.

Also updated a bit more against old ffmpeg version.

Add a few more lockings around other playlist data as well. We really need to redo all this stuff.

macosx: volume needs to be stored in absolute numbers instead of percentages. If you don't do this, the user will get a quite different noise experience...

Closes #2805
