CCGSubSurf: Split file into several smaller ones

This is a preparation commit for having OpenSubdiv integrated into Blender
and new layout is the following:

- CCGSubSurf.c contains implementation of common functions used by both
  legacy subdivisions code and by the new code in the future.

- CCGSubSurf_inline.h contains internal functions which are to be inlined
  due to the performance reasons. Those functions are only ment to be used
  bu CCGSubSurf* files.

- CCGSubSurf_intern.h contains declarations of private functions and data
  structures used by CCGSubSurf module.

- CCGSubSurf_legacy.c contains legacy implementation of subdivision algorithm.

- CCHSubSurf_util.c contains utility functions which are not directly related
  on the subdivision code (i.e. debug functions, hash implementation etc).

There should be no functional changes so far.
