options: allow using % for width and height in --geometry

Now all numbers in the --geometry specification can take percentages.

Rewrite the parsing of --geometry, because adjusting the sscanf() mess
would require adding all the combinations of using and not using %. As
a side effect, using % and pixel values can be freely mixed.

Keep the aspect if only one of width or height is set. This is more
useful in general.

Note: there is one semantic change: --geometry=num used to mean setting
the window X position, but now it means setting the window width.
Apparently this was a mplayer-specific feature (not part of standard X
geometry specifications), and it doesn't look like an overly useful
feature, so we are fine with breaking it.

In general, the new parsing should still adhere to standard X geometry
specification (as used by XParseGeometry()).
