Add UNSAFE_DISABLE_HIDDENAPI_FLAGS to skip hiddenapi processing

Setting environment variable UNSAFE_DISABLE_HIDDENAPI_FLAGS=true
will skip the build step which annotates dex files with information
about public and non-public API membership. This is meant to speed
up incremental local builds.

USE AT OWN RISK: Dex files built with this flag will execute with
hidden API access checks disabled and therefore may exhibit different
behaviour compared to production code.

WARNING: Some JARs cannot be compiled with this flag as ART hardcodes
hidden API access flags of intrinsified methods. Attempting to compile
dex files containing such methods will trigger an assertion.

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For an outdated reference on Android.mk files, see build-system.html.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