455f1bfc05 Do not use many FDs in FontManagerService.
Currently there are over 170 font files are installed in system directory.
Opening 170+ files and keep them is not unacceptable. Pass URI instead.

At the same time, this CL hides full font path from FontConfig since
/system/fonts directory will be deprecated in future.

ac873c9f25 Clean up public FontConfig APIs
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

9ff994d988 Introduce set/getFontVariationSettings.
This is 2nd attempt of I249d464f8cdaa56017a987588b94ed685aadeb58.
The original CL was reverted due to conflicting with another CL submitted
before.
Nothing has changed except for following class name changes.

Here is the original commit message of reverted change.

This CL enables developers to specify axis values to the underlying
font collection. The specification of the font variation settings is
the same as the CSS font-variation-settings attribute in CSS working
draft as of 2016-11-30.

Code example: Here is an example to set width 100 and weight 1.5.

  TextView tv = (TextView) findViewById(R.id.textView);
  tv.setFontVariationSettings("'wdth' 100, 'wght' 1.5");

Bug: 33062398
Test: Manually done. Ran FrameworksGraphicsTests, CtsGraphicsTestCases
      and CtsWidgetTestCases

04d72abde1 Expose fonts.xml via public API with a service
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.

Test: See attached CTS change in topic

0ec4f416ff Allow only U+0020..U+007E characters for axis tag.
CSS Font4 only allows U+0020..U+007E characters for tag string.

a87b07d7fa Add support for gx font variation axes.
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.

8349b7a063 Use 'index' instead of 'ttcIndex' for attribute name.
There are two reasons for this. First, the name 'ttcIndex' is over
specific, there are many indexed font containers in addition to ttc,
such as fon, pfr, bdf, and dfont. There may be others in the future.
Second, Skia implemented this attribute with the name 'index' quite
some time ago. By naming this attribute 'index' even existing apps will
be able to use this attribute (including Chrome).

117cbebe81 New weight-aware font config
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.

f9e3d31127 Language and variant selection for Minikin
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".

9a5b61ccc8 Parsing of XML font configuration files for 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.
