Returns hasVariationSelector true for VS15/VS16
Minikin has a special font fallback for VS15/VS16, so
hasVariationSelector for emojis with VS15/VS16 should always return
true.

Improve Paint.measureText and Paint.hasGlyph for variation sequences.
Before this patch, the font fallback chain iterated all installed font
families if a variation selector was specified.
This CL narrows down the range of iteration.
To decide the font family for the variation sequence, we need to search
for both the variation sequence and its base code point.
The new range of the iteration is a union of them.
With this change, the running time of Paint.hasGlyph for the variation
sequence improves 50% and the running time of Paint.measureText for the
variation sequence improves 40% for the large text case on Nexus 6
userdebug.

Improve Paint.hasGlyph performance by caching hb_font_t
It turned out that hb_font_t creation is not a lightweight operation.
Especially, Paint.hasGlyph creates hb_font_t for all existing fonts
every time. To improve the performance, cache hb_font_t instead
of hb_face_t.
Note that to calculate horizontal advance, MinikinPaint needs to be
associated with hb_font_t by calling hb_font_set_funcs. With this patch,
hb_font_set_funcs may be called multiple times for the same hb_font_t
object. However this is not an issue since MinikinPaint is unique
during layout.

Save all kind of script tags into FontLanguage.
This is 2nd attempt of I8df992a6851021903478972601a9a5c9424b100c.
The main purpose of this CL is expanding FontLanguage to be able to
save full script tag. Previously, FontLangauge kept only limited script
tags. With this CL, FontLanguage keeps all script tags.
This CL contains the following changes:
- FontLanguage changes:
-- Moved to private directory not to be instantiated outside of Minikin.
-- Removed bool(), bits(), FontLanguage(uint32_t) methods which are no
longer used.
-- Change the FontLanguage internal data structure.
-- Introduces script match logic.
- FontLanguages changes:
-- Moved to private directory not to be instantiated outside of Minikin.
-- This is now std::vector<FontLanguage>
- FontLanguageListCache changes:
-- Now FontLanguageListCache::getId through
FontStyle::registerLanguageList is the only way to instantiate the
FontLanguage.
-- Normalize input to be BCP47 compliant identifier by ICU.

Remove script matching score from the font selection fallback.
Removing the extra score of 2 for the script matching from the font
fallback score calculation. If the two langauges have different
scripts, we should treat them as different languages.

Introduce FontFamily::hasVariationSelector
This CL introduces new method hasVariationSelector into FontFamily but it
is not used in production code. So no behavior changes are expected.
This CL contains the following changes:
- Introduce hasVariationSelector which returns true if the corresponding
font has a glyph for a code point and variation selector pair.
- Introduce purgeHbFontCache since hb_face_t won't be released by
keeping hb_font_t.
- Introduce unit tests with self-built font.

Move coverage bitmap from FontCollection to FontFamily
This will significantly reduce memory usage and also speed the creation
of new font families. In particular, the coverage bitmaps for the fonts
in the fallback stack will be computed once in the Zygote, rather than
separately in each app process.

Language and variant selection
This patch adds a "lang" pseudo-CSS property and uses it both to select
an appropriate font and control the "locl" OpenType feature to get the
most appropriate rendering for the langauge and script. In addition,
the "-minikin-variant" property selects between "compact" and "elegant"
variants of a font, as the former is needed for vertically cramped
spaces.
This is part of the fix for bug 15179652 "Japanese font isn't shown on
LMP".

Caching for layouts and harfbuzz faces
This patch adds caching for both layouts and for HarfBuzz face objects.
The granularity of the cache for layouts is words, so it splits the
input string at word boundaries (using a heuristic). There are is also
some refactoring to reduce the amount of allocation and copying, and
movement towards properly supporting contexts.
The size of the caches is a fixed number of entries; thus, it is
possible to consume a large amount of memory by filling the cache with
lots of large strings. This should be refined towards a scheme that
bounds the total memory used by the cache.
This patch fixes bug 15237293 "Regression: Measure performance is
significantly slower with minikin".

Initial commit of Minikin library
This is the initial draft of Minikin, a library intended to perform text
layout functions. This version does basic weight selection and font runs
for scripts, and also has a simple renderer for drawing into bitmaps,
but is lacking measurement, line breaking, and a number of other
important features. It also lacks caching and other performance
refinements.
