Build android.test.base/legacy against SDK
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.

# Build the android.test.legacy library
# =====================================
+# Built against the SDK so that it can be statically included in APKs
+# without breaking link type checks.
+#
+# This builds directly from the source rather than simply statically
+# including the android.test.base-minus-junit and
+# android.test.runner-minus-junit libraries because the latter library
+# cannot itself be built against the SDK. That is because it uses on
+# an internal method (setTestContext) on the AndroidTestCase class.
+# That class is provided by both the android.test.base-minus-junit and
+# the current SDK and as the latter is first on the classpath its
+# version is used. Unfortunately, it does not provide the internal
+# method and so compilation fails.
+#
+# Building from source avoids that because the compiler will use the
+# source version of AndroidTestCase instead of the one from the current
+# SDK.
+#
+# The use of the internal method does not prevent this from being
+# statically included because the class that provides the method is
+# also included in this library.
