Update harfbuzz to 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.


Overview of changes leading to 1.2.2
Wednesday, February 24, 2016
====================================

- 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.


Overview of changes leading to 1.2.1

- CoreText: Drastically speed up font initialization.
- CoreText: Fix tiny leak.
- Group ZWJ/ZWNJ with previous syllable under cluster-level=0.
