I don't see the need to export these in x265.h as these are only utilized
inside the library.

Objects of this struct are only every accessed through objects of
x265_analysis_data_t. If that is the case, can we fold these fields into
the x265_analysis_data_t struct and remove this struct?
Nested structs aren't a great idea as it makes backwards compatibility a
pain!
