releasetools: Make apex_utils Python 3 compatible.

In order to get a Python 2 and 3 compatible re-raise behavior, this CL
removes the stack traceback for the lines within apex_util module (i.e.
sys.exc_info()[2]). It's not a big loss in practice, since we only have
one line within the try-except block (`common.RunAndCheckOutput()`)
that's no longer reported in the traceback.

Using `six` module could better solve this, but only after building
releasetools as python_binary_host modules where we can properly handle
the module dependency.

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For an outdated reference on Android.mk files, see build-system.html.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