vo_x11: use generic aspect ratio code, refactor

Instead of manually calculating aspect ratio etc., use
vo_get_src_dst_rects(). This has the advantage that we can drop some
special cases in aspect.c later.

Simplify the code, and move resizing the X images from draw_image() to a
new resize() function.

Do some other simplifications. The gXErrorFlag check was actually dead
code, even in mplayer-svn. Special-casing on WinID is not needed
anymore (we created an embedded window, and its size is updated by
x11_common.c).
