Add Docker instructions for older branches 

If you've upgraded away from Ubuntu 14.04 Trusty, you may find that
older branches (or certain code) doesn't build anymore. These
instructions can form a starting point to build these older branches
within Docker.

Bug: 72993575
Test: Follow instructions, build marshmallow-dev
Test: Follow instructions, build lollipop-mr1-dev

The Dockerfile in this directory sets up an Ubuntu Trusty image ready to build

a variety of Android branches (>= Lollipop). It's particulary useful to build

older branches that required 14.04 if you've upgraded to something newer.



First, build the image:

```

# Copy your host gitconfig, or create a stripped down version

$ cp ~/.gitconfig gitconfig

$ docker build --build-arg userid=$(id -u) --build-arg groupid=$(id -g) --build-arg username=$(id -un) -t android-build-trusty .

```



Then you can start up new instances with:

```

$ docker run -it --rm -v $ANDROID_BUILD_TOP:/src android-build-trusty

> cd /src; source build/envsetup.sh

> lunch aosp_arm-eng

> m -j50

```
