Implement support for downloadable font requests in xml. Given the
xml fonts feature in O, this adds support to not only declare
local font files as font resources, but also Downloadable fonts
from a fonts provider.
A provider returns a font family (of one or more files) given a
query, so the new attributes are added to the font-family tag.
Additionally, add support to pre-declare downloadable font resources
in the Android Manifest. These will then be fetched at app startup
time so they are available to use from the Typeface cache asap.
When retrieving downloadable fonts via resources, the cache is
checked to see if the font is already there and is used, otherwise
a request is sent to the provider and the default font is returned
as we need a result synchronously.
To do this, the developer declares an additional fonts xml resource
file with the list of fonts to preload and links it in the manifest
with a meta-data tag.
E.g.:
res/font/mydownloadedfont.xml
<font-family xmlns:android="http://schemas.android.com/apk/res/android"
android:fontProviderAuthority="com.example.test.fontprovider"
android:fontProviderQuery="myrequestedfont">
</font-family>
res/font/preloaded_fonts.xml
<?xml version="1.0" encoding="utf-8"?>
<font-family xmlns:android="http://schemas.android.com/apk/res/android">
<font android:font="@font/mydownloadedfont" />
</font-family>
and in the AndroidManifest.xml
<meta-data android:name="preloaded_fonts"
android:resource="@font/preloaded_fonts" />

With the introduction of support for 16 bit images, bitmaps returned
by BitmapFactory may be using the RGBA_F16 configuration. Some apps
and libraries assume the returned configuration is always ARGB_8888
and make assumptions based on that to compute cache sizes, etc.
This changes extract the output config when BitmapFactory is invoked
with the inJustDecodeBounds option. Despite its name, this option
is already used (and documented!) to decode more than bounds as it
also decodes the MIME type.

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");

- Reads in the mask path from config.
- If <maskable-icon> is dynamically created, clip the drawable using the mask path.
- Instead of using clipPath method, used BitmapShader for performance.

This change exposes to developers the ability to request fonts
from a provider via Typeface.
Until further security is implemented, only system apps can
provide fonts.

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@.

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.

A graphic buffer is most useful, as we can both attach it
to starting windows, and directly use it in Sys-UI. The old
codepath for starting windows/saved surfaces, is co-existing
at the moment, so I don't make large attempts to clean up
the existing screenshot code.
