Check VINTF compatibility at OTA generation time.

Instead of relying on META/{system,vendor}_{manifest,matrix}.xml
and blindly copy compatibility.zip from target files package to
OTA package, do a static check on the input target files package
before generating the OTA package.

META/{system,vendor}_{manifest,matrix} does not contain ODM manifest
fragments, which is incorrect.

Also, the on-device check of compatibility.zip uses a old libvintf
binary on the device, which may not understand the incoming VINTF
metadata. This change removes the on-device check. Hence, it removes
the requirement of forwards compatibility of libvintf.

This behavior can be skipped with --skip-compatibility-check.

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For an outdated reference on Android.mk files, see build-system.html.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.
