Currently the V4L2 device to be used can only be set via the media URL.
This patch allows the :v4l2-dev option to set the device as well.
Setting the device via the media URL still takes precedence.

This is useful if a program auto-detects the V4L2 device so that the
media URL only needs to contain e.g. the tuner settings.

Don't define HAVE_LINUX if you don't have it in the first place.
And this does not even respect the configure message rules.

This fixes a memory leak, encoding problems, and complete failure on
non-file inputs.

access_dtv for Android systems.

"podcast-urls" is autosaved in any case.

Bookmark configuration items are not in hotkeys (at least currently),
so this could not work.
