  [autofit] Rewrite HarfBuzz interface to support character clusters.
  
  Scripts like Khmer have blue zones that can't be directly
  represented by Unicode characters.  Instead, it is necessary to let
  HarfBuzz convert character clusters into proper glyph representation
  forms, then deriving the blue zone information from the resulting
  glyphs.
  
  * src/autofit/hbshim.c, src/autofit/hbshim.h: Replaced by...
  * src/autofit/afshaper.c, src/autofit/afshaper.h: ... these two new
  files, providing a new API to access HarfBuzz.
  
  The new API manages a HarfBuzz buffer with `af_shaper_buf_create'
  and `af_shaper_buf_destroy'.  The buffer receives a UTF8 encoded
  string with function `af_shaper_get_cluster', and the resulting
  glyph data (indices, advance widths, vertical offsets) can be
  iteratively accessed with function `af_shaper_get_elem'.
  
  * src/autofit/afcjk.c (af_cjk_metrics_init_widths,
  af_cjk_metrics_init_blues, af_cjk_metrics_check_digits): Updated.
  
  * src/autofit/aflatin.c (af_latin_metrics_init_widths,
  af_latin_metrics_init_blues, af_latin_metrics_check_digits):
  Updated.
  
  * include/freetype/internal/fttrace.h: s/afharfbuzz/afshaper/.
  
  * src/autofit/afglobal.c: s/hbshim.h/afshaper.h/.
  (af_face_globals_compute_style_coverage): Updated.
  
  * src/autofit/afglocal.h: s/hbshim.h/afshaper.h/.
  
  * src/autofit/autofit.c: s/hbshim.c/afshaper.c/.
  
  * src/autofit/Jamfile, src/autofit/rules.mk (AUTOF_DRV_SRC):
  Updated.
