Suggested by Alexei. `UL' is only needed for 16bit compilers, but
it seems noone is using this anymore (and we no longer test whether
FreeType compiles in such an environment). Otherwise, it is easy to
add the postfix to the `AF_UNICODE_RANGE' macro.

Georgian is problematic, since `uppercase' forms of Mkhedruli
(called Mtavruli) are not yet defined in Unicode, which means that
proper blue zones can't be defined. However, there is already a
proposal submitted to Unicode; see
http://www.unicode.org/L2/L2016/16034-n4707-georgian.pdf
Additionally, due to historical reasons, Unicode treats Khutsuri as
the same script as Mkhedruli, and so does OpenType. However, since
the two scripts have completely different shapes it can happen that
blue zones differ considerably. The tag `geok' used here (derived
from ISO 15924) to differentiate the two scripts is not an OpenType
tag in use. If we now have a font that contains both glyphs for
Mkhedruli and Khutsuri, and it uses OpenType features for both also,
HarfBuzz unavoidably treats all glyphs as `geor'. As a consequence,
blue zones for `geok' are not used for glyphs involved in the
OpenType features.
An issue not yet resolved is which OpenType feature should be used
to access Mtavruli glyph shapes; right now, FreeType doesn't set up
support for them, but it is easy to add them later on as soon as
more information is available.

This patch introduces auxiliary code ranges that identify no-base
characters; they refer to glyphs of a script that should be hinted
without alignments to blue zones (mostly diacritics).
It also splits off ranges for fallback scripts that handle subscript
and superscript characters not covered by OpenType features. For
example, this greatly helps improve the hinting of various phonetic
alphabets, which contain a large amount characters that look like
superscript glyphs.
Finally, code ranges are updated to Unicode 8.0, and enclosed
characters are removed in general since they normally look better if
they stay unhinted.
* src/autofit/afranges.c (af_latn_uniranges): Updated to Unicode
8.0.
Split off superscript-like and subscript-like glyphs into...
(af_latb_uniranges, af_latp_uniranges): ... these two new arrays.
(af_xxxx_nobase_uniranges): New arrays that hold no-base characters
of the corresponding character ranges.

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.
