    include/freetype/cache/ftcmanag.h
    include/freetype/cache/ftcmru.h
    include/freetype/cache/ftcsbits.h:
      removing these header files from the public include directory.

    * include/freetype/config/ftheader.h:
      changing the definition of FT_CACHE_INTERNAL_XXX_H macros to
      redirect to FT_CACHE_H instead

    * src/cache/ftcbasic.c, src/cache/ftccache.c, src/cache/ftccache.h,

    src/cache/ftcmru.h, src/cache/ftcsbits.c, src/cache/ftcsbits.h:
      modifications to prevent using the FT_CACHE_INTERNAL_XXX_H macros,
      and grab the headers in 'src/cache' instead (see below).
