Add fingerprint to packages.map.

No guards to this change because we will guard actually writing the
fingerprint, and right now new storage is not in trunkfood yet. This
change modifies the package map file structure. Note that if the new
storage was in trunkfood, this could (theoretically) cause issues if
there were cross-container READ_WRITE flags (not permitted per
documentation) and if the containers were built at separate aconfig
versions (ie before and after this change). Adding the fingerprint will
help prevent such issues in the future. Incremented the storage version
number as I've changed the format.

Again, fingerprint is not actually written in this CL, it always has a
value of 0.

Updated the test files as well to have the new version and the
fingerprint. Since this changed the package node size, some of the
information in the buckets there (offset) has changed as well.

Also added a test util for flags from another package to test future
changes.

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For an outdated reference on Android.mk files, see build-system.html.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