setFallbackTypeface is returned by Builder.build() method when the
provided font is not loaded due to some reasons.
The fallback family is resolved with width/italic passed to Builder.

This CL cleans up APIs around font variation settings.
- Remove FontConfig and FontManager public API.
- Remove FontManagerService from system service.
- Extract inner class FontConfig.Axis as top-level class FontVariationAxis.
This is used by Typeface.Builder public API to create new Typeface.
- Introduce and expose FontVariationAxis utility functions from/to string.
- Throws if the invalid font variation settings is passed.
Test: android.text.cts.FontVariationAxisTest passes
Test: android.graphics.cts.TypefaceTest passes
Test: android.graphics.cts.PaintTest passes

Introduce Builder class for creating Typeface from various
sources with optional TTC index and font variation settings.

This CL contains following clean up:
- Hide unnecessary constructors.
- Change List<XX> to XX[] since actually all fields are immutable.
- Change font's variant type from String to int.
- Decouple resource related members to FontResourcesParser.
- Add NonNull/Nullable to all fields.
Test: ran android.content.res.FontResourcesParserTest

This is 2nd attempt of Id10ca97f6f6f5bbe4999c1ad2736423a204d6e87.
The root caus of crash is due touching null pointer in nUnrefFamily.
After above change, native object may not be created on error case.
In that case, nUnrefFamily can not be called. In addition to this issue
there is also memory leak on error case. This fixes it by introducing
abortCreation method.
Also this contains fix of layout lib breakage done by jgaillard@.

Here is original commit message of reverted change.
minikin::FontFamily no longer has addFont function, instead it accept
vector of Fonts in its constructor. To follow this signature change,
holding minikin::Font instance in native and build minikin::FontFamily
instance in FontFamily.freeze() method.

This change creates a new FontManagerService, in charge of providing
font management data. It exposes a public API to retrieve the
information in fonts.xml without accessing it directly. To do this,
it also refactors FontListParser's internal classes into a new public
FontConfig class holding all the font data.
getSystemFonts() returns all the available information in fonts.xml
as well as file descriptors for all the fonts. This allows us to
share the memory consumed by these files between all clients.

Minikin is changing its approach to table access to use HarfBuzz to
access the tables, based on raw font data, rather than calling the
MinikinFont::GetTable() virtual method. This patch provides raw access
to the font data to make this work.
There's a bit of plumbing to make sure fonts get a pointer to the raw
data as well.

With ttc and gx variation fonts, it is now possible and common that a
number of fonts will use the same font file for data but with different
parameters. In the current code each font will map the font file data,
taking up an unecessary amount of virtual address space and is
inefficient with respect to memory management (like the tlb). This CL
deduplicates these file mappings so that a given font file will only be
mapped into memory once.

(cherry picked from commit fffcf0a31f)
This adds an 'axis' child element to the 'font' element. The 'axis'
element has attributes 'tag' (a four byte identifier) and 'stylevalue'
(a float value) to the parser. This also modifies reading the font file
name in a backwards compatible fashion by using only the direct #text
children of the 'font' element. (Both the Minikin and Skia parsers now
allow the font file name on a separate line in the fonts.xml file).
This information is then passed through to Skia in order to select the
desired variation. The Skia parser already parses this way and has for
some time, so Chrome and WebView can already read this format.

Parse new fonts.xml config file, and resolve weight selection based on
the base weight of the font (as defined by a weight alias specified in
the config file) and the requested bold flag. This change improves the
appearance of bold spans for alternate weights of Roboto.
In addition, this patch enables weight selection for fallback fonts.
For example, if an additional font with a weight of 100 is added to the
Hebrew font family in the fallback list, then requesting
"sans-serif-thin" would select that font for Hebrew text.

This patch adds the fallback font list to custom typefaces created from
files and assets, as well as those created by name. This is a fix for
the deskclock half of bug 15139067 "Centered text isn't working".

This is the frameworks/base side of what's needed to support language
selection (especially Han unification, but also compact/elegant
selection for scripts that require more vertical space).
This is part of the fix for bug 15179652 "Japanese font isn't shown on
LMP".

This adds the new delegates that were missing. This starts the work on
changes related to Minikin Fonts.
There are some changes related to TypedArray that still need to be
fixed.

This patch introduces proper lifecycle maintenance (based on reference
counting) for Minkin objects, particularly FontFamily and
FontCollection. The patch depends on the corresponding Ref and Unref
methods being available in Minikin.

This patch improves Minikin-based font handling, to deal with error
conditions (missing fonts and so on), and also moves the parsing of
fallback_fonts.xml and system_fonts.xml into Java code.

This is the current state of the Minikin integration. All changes are
hidden behind USE_MINIKIN #ifdef, so it should be safe to apply. To
play with the Minikin branch, set this in your BoardConfig.mk .
This change also merges in 64-bit changes that were happenening in
parallel.
