b568f20f32 swscale/rational64: add 64-bit rational type 
This is needed by the ops code, to represent intermediate values for 32-bit
formats, which can exceed the value range of int32_t (especially for
intermediate products).

I copied the math almost 1:1 from rational.c, but adapted to use the 128-bit
integer wrappers defined by int128.h. I added a generous amount of tests in
any case.
