This includes two changes.
- Change all methods in MediaSession2.BuilderBase signatures from
public to package private.
- Subclasses of MediaSession2.BuilderBase (MediaSession2.Builder,
MediaLibraryService2.MediaLibrarySessionBuilder) now inherit all
methods from its super class and change method signatures to public
Changes are needed to workaround and fix following issues.
- Hidden super class's methods aren't shown in the Javadoc and 3rd
party apps cannot use them.
- Public generic methods in the super classes are shown in the Javadoc
with the generic types (e.g. 'U setSessionCallback()' instead of
'Builder setSessionCallback()')
- Stub classes for tests are automatically generated, but it somehow
fails to generate stub for the BuilderBase (seems like a bug)
Test: 'm update-api' and checked generated javadoc

There are several places across the OS where Java code is simply
copying data between two points, which requires bringing that data
out into userspace before going back into the kernel. (That's pretty
lame.) The patches for the recent Meltdown/Spectre security issues
have made this overhead even worse, so it's finally time to move this
copying directly into the kernel.
This change adds a couple new FileUtils.copy() methods which inspect
the given streams/FDs, and attempt to do as much optimization as
possible before falling back to a slower userspace-based copy.
Benchmarks are showing typical improvements of 44% for 32KB files,
50% for 32MB files, and 35% for 32MB pipes.
Plenty of tests are included, and there's a simple kill-switch that
can be used to enable/disable the feature if it starts causing any
trouble. (A future CL will enable the optimizations.)

This CL removes the show/hide API from MediaControlView2 and instead
provides the developer with the same function by calling
setVisibility(View.VISIBLE | View.GONE), and calling the new APIs
set/getTimeout() and requestPlayButtonFocus(). The original Runnable
code has been moved to onVisibilityAggregated() as per API council's
request.
Test: build
