Create a new kati packaging step; move dist

Instead of looking at `dist` and DIST_DIR directly in the Kati Build
step, always write out information about every call to dist, then create
the rules in another ckati run.

So instead of having:

  dist:    <goal> -> <dist> -> <output>
                \______________↑

  nodist:  <goal> -----------> <output>

Always use another phony target in the Kati Build step:

   <goal> ---> <output>
        \----> _dist_<goal>

Then in the packaging step (which is much faster), choose between dist
and no dist:

  dist:   _dist_<goal> -> <dist> -> <output>

  nodist: _dist_<goal>

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For an outdated reference on Android.mk files, see build-system.html.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