refinements.

* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.

This essentially moves the Devanagari script from the `Indic' hinter
to the `Latin' hinter. Thanks to Girish Dalvi
<girish.dalvi@gmail.com> for guidance with blue zone characters!
* src/autofit/afblue.dat: Add blue zone data for Devanagari.
* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.

Split the single, incorrect Indic entry into separate scripts so
that the covered ranges are the same: Bengali, Devanagari, Gujarati,
Gurmukhi, Kannada, Limbu, Malayalam, Oriya, Sinhala, Sundanese,
Syloti Nagri, Tamil, Telugu, and Tibetan. At the same time, remove
entries for Meetai Mayak and Sharada – the Unicode ranges were
incorrect (and nobody has complained about that), fonts are scarce
for those scripts, and the Indic auto-hinter support is rudimentary
anyways.
* src/autofit/afscript.h: Updated, using AF_CONFIG_OPTION_INDIC and
AF_CONFIG_OPTION_CJK.
* src/autofit/afstyles.h (STYLE_DEFAULT_INDIC): New auxiliary macro.
Use it, together with AF_CONFIG_OPTION_INDIC and
AF_CONFIG_OPTION_CJK, to update.
* src/autofit/afranges.c [AF_CONFIG_OPTION_INDIC]: Updated.
[!AF_CONFIG_OPTION_INDIC, !AF_CONFIG_OPTION_CJK]: Removed.
Sort entries by tags.
* src/autofit/afcover.h: Remove coverages for alternative fractions,
denominators, numerators, and fractions.
* src/autofit/afstyles.h (META_STYLE_LATIN): Updated.
* src/autofit/afstyles.h (STYLE_LATIN, META_STYLE_LATIN): New
auxiliary macros; use them to define styles for Cyrillic, Greek, and
Latin.
* src/autofit/afcover.h: Remove coverage for oldstyle figures.
Since those digits are used in combination with ordinary letters, it
makes no sense to handle them separately.
* src/autofit/afglobal.c (af_face_globals_get_metrics): Don't limit
`options' parameter to 4 bits.
Coverages are the interface to the HarfBuzz library to access
OpenType features for handling glyphs not addressable by the cmap.
Right now, compilation of HarfBuzz is only added to the development
build. A solution for standard build mode will be delayed until
HarfBuzz gets split into two libraries to avoid mutual dependencies
between FreeType and HarfBuzz.
Note that this is only a first step in handling coverages, basically
providing the framework only. Code for handling selected OpenType
features (this is, actually using the data in `afcover.h') will
follow.
* devel/ftoption.h, include/config/ftoption.h
(FT_CONFIG_OPTION_USE_HARFBUZZ): New macro.

New files.

* src/autofit/aftypes.h: Update use of `SCRIPT' and `STYLE' macros.

data.
* src/autofit/afglobal.h: Update use of `SCRIPT' and `STYLE' macros.

Update use of `SCRIPT' and `STYLE' macros.
(af_face_globals_compute_style_coverage)
[FT_CONFIG_OPTION_USE_HARFBUZZ]: Call `af_get_coverage'.
Update.
* src/autofit/afmodule.h (AF_ModuleRec):
s/fallback_script/fallback_style/.
* src/autofit/afmodule.c (af_property_set): Adapt handling of
`fallback-script' property to set a fallback style.
(af_property_get, af_autofitter_init): Updated.
* src/autofit/afpic.c: Update use of `SCRIPT' and `STYLE' macros.
* src/autofit/afranges.h: Update use of `SCRIPT' macro.
