Structure MediaProvider as an APEX.

Based on guidance from the Mainline team, we're placing the
MediaProvider APK inside a new APEX, as this will allow us to
move MediaStore.java inside the module boundary in a future CL.

As part of this restructuring, we need the pre-Mainline APK to
remain intact to preserve the user's media database.  There is
already logic in place from previous CLs that will migrate data
from the pre-Mainline to the post-Mainline world, including tests
to verify that the migration works.

Android Make Build System

This is the Makefile-based portion of the Android Build System.

For documentation on how to run a build, see Usage.txt

For a list of behavioral changes useful for Android.mk writers see Changes.md

For an outdated reference on Android.mk files, see build-system.html. Our Android.mk files look similar, but are entirely different from the Android.mk files used by the NDK build system. When searching for documentation elsewhere, ensure that it is for the platform build system -- most are not.

This Makefile-based system is in the process of being replaced with Soong, a new build system written in Go. During the transition, all of these makefiles are read by Kati, and generate a ninja file instead of being executed directly. That's combined with a ninja file read by Soong so that the build graph of the two systems can be combined and run as one.
