Split the vo_vdpau code that calculates how to pack all subtitle
bitmaps into a larger surface into a separate file. This will allow
using it in other VOs.
Conflicts:

Note: this commit does the same as an earlier commit by me
(4010dd0b1a). My commit added the vo_vdpau packer code as
eosd_packer.c, while this commit by uau uses bitmap_packer.c. Since
bitmap_packer.c has a different interface, and because there are more
commits changing OSD rendering coming, I will pick uau's version.
However, vo_gl, vo_gl3 and vo_direct3d are still using eosd_packer.c,
so to make the transition easier, don't delete eosd_packer.c yet.
