Add support enforcing all path requirements.

Setting PRODUCT_ENFORCE_ARTIFACT_PATH_REQUIREMENTS to be non-empty will
verify that when an inherited product file makes an path requirement
claim, no files other than the ones it produces are allowed inside its
paths. This allows more rigorous control of what goes where, and
specifically stops accidental inclusion of modules in the wrong places
(which is very easy to do otherwise).

In order to enable iterative improvements to current offenders, support
for a whitelist is also added (via the new
PRODUCT_ARTIFACT_PATH_REQUIREMENT_WHITELIST property). Verification is
done that this variable corresponds to exactly the list of current
offenders.

Example use:
  PRODUCT_ENFORCE_ARTIFACT_PATH_REQUIREMENTS := true
  PRODUCT_ARTIFACT_PATH_REQUIREMENT_WHITELIST := system/priv-app/Dialer/Dialer.apk

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For an outdated reference on Android.mk files, see build-system.html.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