'make fetch' has to fetch sources for all the built packages,
including dependency packages. Conversely, 'make fetch' should not
fetch sources of distro-provided packages, not even dependencies.
This should fix that.

As an minor bonus, 'make .foo' should now work even if foo is
provided by the distro, and conditional build rules should be cleaner.

Remove the old way with using the static makefiles and weird ??PREFIX?? patches

Same, not libav* enabled

macosx: removed headphone virtualization and normvol filter from simple prefs since these options are part of the audio filter panel now

just don't build the cli

Remove some useless cast changes. Apply the patch always as it is
correct on all architecture. Drop the errno code part which is wrong
(live needs the Winsock error codes, not the <io.h> ones).

fffmpeg -> ffmpeg
