VO: remove code duplication for setting up mp_osd_res

Browse Source 
vo_opengl, vo_vdpau, vo_direct3d had the code for setting up mp_osd_res
duplicated. Make things simpler by making calc_src_dst_rects() setup
the full mp_osd_res structure, instead of just "borders".

Also, rename that function to vo_get_src_dst_rects(), and make it use
mp_rect. Remove vo_rect, which was annoying because it contains
redundant members (width/height additional to right/bottom).

Add code to print the video rect etc. in verbose mode.

There should be no actual change how the video rects are calculated. The
only exception are the bottom/right subtitle margins, which are now
computed slightly differently, but that shouldn't matter.
