This is a ground work for b/114479228
FontStyle is an argument of the font itemization. Currently Android
system uses weight and italic info for itemizing but maybe we will
use width and oblique style in future.
To be extensible in future, introduce FontStyle.
This CL includes:
- new class FontStyle which holds width and italic at this moment. In
future, we may add width and oblique. (or grdual italic slant)
- Font class still returns weight/slant since they need to be immutable.
- Moved font weight constants from Font to FontStyle

Giving any range to the Builder is too much freedum and hard to tell
errors. Changes to accept length instead of ranges. By this change, we
can prevent and tell errors about
- The gap in the text that no Paint is assigned.
- The given range is overlapped.
- The given range exceeds the text length.

Obtaining a thumbnail for a Uri requires opening it with the slightly
obscure openTypedAssetFileDescriptor(), passing in "image/*" with the
right Bundle of EXTRA_SIZE to hint the target area on screen, and
defensively scaling any returned results.
This is pretty tedious to get right, so offer a convenience method
that does all this for the developer. Internally uses ImageDecoder
to follow best-practices, and replaces older getDocumentThumbnail()
implementation by delegating to this one.
A future CL will teach ImageDecoder about how to read any embedded
EXIF thumbnails, including any required rotation.

The transfer function of Display P3 should be sRGB transfer function,
previously we defined f as 0.039, however, the sRGB transfer function defines f
as 0.04045. This patch fixes it.

Although the old one works for [0,1], Skia has switched to this new
representation because it has the following nice properties:
- it extends cleanly above 1
- it's unambiguously defined
Having ColorSpace out of sync results in mismatches between those
objects underlying SkColorSpace objects when they should be the same.

This CL includes:
- Move NativeLineBreaker/NativeMeasuredParagraph to android.graphics.text
package since these two uses the shaping result of the text which is a
part of graphics responsibility. At the same time, by this moving,
minikin is only used by android.graphics package.
- Rename NativeLineBreaker/NativeMeasuredParagraph to
LineBreaker/MeasuredText.
- Updated comments of the break strategy and hyphenation frequency.

ContentResolver.openTypedAssetFileDescriptor() has support for a
Bundle of options that can be used to communicate things like desired
thumbnail size, and also CancellationSignal to cancel large network
fetches when no longer needed.
Instead of adding all these to ImageDecoder, let developers provide
their own Callable<AssetFileDescriptor> so they can implement these
custom features.

Add the relevant methods to read from ProtoInputStream to
various classes.
Also add some framework to handle version changes in
UsageStatsDatabase. There is some risk of users losing all their current
UsageStats data, if something goes horribly wrong. The debug flag and a
keep backup files flag are temporarily set in UsageStatsDatabase with
this change. They will both be unset in the future before the Q release.
Some rough number on the impact of this change:
Proto file size on disk reduces to ~47% of XML file size :)
Proto file read time reduces to ~55% of XML file read :)
Proto file write time increases ~17% over the XML file write :(
There will be a follow up CL to address the file write time regression

Paint#hasEqualAttributes is not a equal method in Paint.
TextLine depends on this method but making this public will make
developer confused. So, moving hasEqualAttributes to TextLine and
provide some accessors for shadow layer parameters.
For the TextPaint, unhide underlineColor and underlineThckness for
implementing equalAttributes in TextLine.

Creating HashSet and LocaleList in Zygote make performance impact
to the boot time. Since this API is not called so frequently and less
application is expected to call this API. So let's make Set and
LocaleList only when it is requested.
