neutrino: rework infoviewer

Make the infoviewer more "tuxbox-like". The default appearance should
only change marginally, but this provides infrastructure to:
*) disable the crypto icons (default if --disable-blinkenlights)
*) resize the infobar better to adapt to changed font sizes (not yet
 perfect, but better than before)
*) always vertically center the icons in the button bar (red green blue
 and AC3/16:9 etc)
The one thing visible immediately is that the infobar is always drawn
at the same height, regardless if the buttonbar is drawn below or not.
Originally I did it that way because a) the code was simpler and b) I
liked it better. If this is an issue, please report an I can change that.

I deliberately did not touch the display in file playback mode, this can
be done later once potential issues are shaken out.

Tis is a massive change, so I expect it to be not perfect. Please report
anything you find.
