harfbuzz: update 1.2.1 -> 1.2.3

Overview of changes leading to 1.2.3
Thursday, February 25, 2016
====================================

- Blacklist GDEF table of certain versions of Times New Roman (Bold) Italic,
  due to bug in glyph class of ASCII double-quote character.  This should
  address "regression" introduced in 1.2.0 when we switched mark zeroing
  in most shapers from BY_UNICODE_LATE to BY_GDEF_LATE.
  This fourth release in a week should finally stablize things...

- hb-ot-font's get_glyph() implementation saw some optimizations.  Though,
  might be really hard to measure in real-world situations.

- Also, two rather small API changes:

We now disable some time-consuming internal bookkeeping if built with NDEBUG
defined.  This is a first time that we use NDEBUG to disable debug code.  If
there exist production systems that do NOT want to enable NDEBUG, please let
me know and I'll add HB_NDEBUG.

Added get_nominal_glyph() and get_variation_glyph() instead of get_glyph()

New API:
- hb_font_get_nominal_glyph_func_t
- hb_font_get_variation_glyph_func_t
- hb_font_funcs_set_nominal_glyph_func()
- hb_font_funcs_set_variation_glyph_func()
- hb_font_get_nominal_glyph()
- hb_font_get_variation_glyph()

Deprecated API:
- hb_font_get_glyph_func_t
- hb_font_funcs_set_glyph_func()

Clients that implement their own font-funcs are encouraged to replace
their get_glyph() implementation with a get_nominal_glyph() and
get_variation_glyph() pair.  The variation version can assume that
variation_selector argument is not zero.  Old (deprecated) functions
will continue working indefinitely using internal gymnastics; it is
just more efficient to use the new functions.

====================================

- Fix regression with mark positioning with fonts that have
  non-zero mark advances.  This was introduced in 1.2.0 while
  trying to make mark and cursive attachments to work together.
  I have partially reverted that, so this version is much more
  like what we had before.  All clients who updated to 1.2.0
  should update to this version.
