android.test.legacy is now build against SDK, thus available to apps
build with SDK.

In doing so, android.test.mock.stubs had to be built with SDK (because
it is used by android.test.legacy). However, this wasn't trivial.

The problem was that some classes in test-mock implemented abstract
methods of platform classes. Even though they are marked as @hide,
doclava automatically emit them to the stub file because otherwise the
class in the stub file does not implement some abstract methods from its
parent class, which in turn makes the stub file non-compilable.

This CL solves the problem by introducing an adapter class in between
the class in test-mock and the class in the framework. The adapter class
implements abstract methods which are @hide and having reference to
types that aren't available to SDK. The abstract methods are removed
from the original class. Then doclava does not emit the abstract
methods.

Also by @hide'ing the adapter classes, they are not compiled when
building the stub library.

This adds a new --start-child-zygote argument that instructs the main
zygote to create a new child process that will also be a zygote. The
system_server generates a random name in the abstract socket namespace
for it and the child-zygote to communicate over, and that is passed as
an argument to the new process.

A child-zygote bypasses the normal post-fork-child of the zygote process
in order to preserve itself as a zygote. This means not starting the
Binder threadpool nor launching into ActivityThread. Instead, a
child-zygote calls into its own main function. The main function runs a
ZygoteServer select loop, listening on the socket name specified by the
system_server when it was forked.

Unlike the system zygotes, a child-zygote can be killed without bringing
down the system. Killing a child-zygote will not terminate its child
processes, which will be reparented to init for reaping when they
eventually exit.

The Doc string for LTE timing advance incorrectly
lists the range based on the maximum size of an
