Add a tool to export a kati stamp file to other tools

There's a desire to understand which files are used by a build so that
the automated builds can make better guesses at which builds should be
run for a certain change. Instead of having them read a stamp file
directly, which would prevent us from updating the stamp format in the
future, build a tool that can be used to export the contents in a stable
and more portable format.

Right now, this just means exporting the file list to stdout with
newlines as delimiters. An idea for the future is to define a protobuf
or similar format that would contain the glob and shell information as
well (if it's useful).

kati

Build Status

kati is an experimental GNU make clone. The main goal of this tool is to speed-up incremental build of Android.

Currently, kati does not offer a faster build by itself. It instead converts your Makefile to a ninja file.

How to use for Android

Now AOSP has kati and ninja, so all you have to do is

% export USE_NINJA=true

All Android's build commands (m, mmm, mmma, etc.) should just work.

How to use for Android (deprecated way)

Set up kati:

% cd ~/src
% git clone https://github.com/google/kati
% cd kati
% make

Build Android:

% cd <android-directory>
% source build/envsetup.sh
% lunch <your-choice>
% ~/src/kati/m2n --kati_stats  # Use --goma if you are a Googler.
% ./ninja.sh

You need ninja in your $PATH.

More usage examples (deprecated way)

"make clean"

% ./ninja.sh -t clean

Note ./ninja.sh passes all parameters to ninja.

Build a specific target

For example, the following is equivalent to "make cts":

% ./ninja.sh cts

Or, if you know the path you want, you can do:

% ./ninja.sh out/host/linux-x86/bin/adb
