This should fix the build with recent automake (fix #6911).

Arguably, this patch is really just a work-around for a bug in the
E/S output.

It closes #4409.

It fixes the playback of the audio of some old AVI DV files.

It closes #4585.

It close #4828 and #3685.

It will allow to share them with the AVI demuxer.

this breaks consitency with the other OS X intf code, but is far more readable

This would allow creating audio output objects in different context.

This should fix #6875

Anyway V4L1 is dead, so there is no ambiguity.

Cameras such as D-Link's DCS-932L don't provide the first video
boundary.

This fixes the freetype ATS lookup for some Asian fonts such as Hiragino Micho ProN with multiple weights.

freetype: in case the provided font name is neither found by name nor by family, let ATS check whether it is a correct PostScript name

This fixes issues with some Asian fonts as pointed by Naohiro Koriyama

freetype: provide a proper fix to prevent ATS from crashing when searching for the font family instead of the fontname
