galileo: Add support for containerized build environment

Browse Source 
This patch adds a Dockerfile for building a container configured as a
build environment for Intel Galileo boards.  This patch also provides
documentation for using the containerized build environment.  Finally, it
streamlines the instructions for booting Contiki on Galileo and includes
other documentation refinements.

Building
--------
Preparation
-----------
Prerequisites on all Ubuntu Linux systems include texinfo and uuid-dev.
Additional prerequisites on 64-bit Ubuntu Linux systems include
gcc-multilib and g++-multilib.
Docker can optionally be used to prepare an Ubuntu-based, containerized build
environment. This has been tested with Docker installed on Microsoft Windows 10.
If not using a containerized environment, proceed to the "Building" section
below.
Using a Docker-based environment on Windows requires that the repository has
been checked out with Git configured to preserve UNIX-style line endings. This
can be accomplished by changing the 'core.autocrlf' setting prior to cloning
the repository [5]:
```
git config --global core.autocrlf input
```
Note that this is a global setting, so it may affect other Git operations.
The drive containing the repository needs to be shared with Docker containers
for the following steps to work [6]. Note that this is a global setting that
affects other containers that may be present on the host.
Open Microsoft PowerShell and navigate to the base directory of the repository.
Run the following command to create the build environment:
```
docker build -t contiki-galileo-build platform/galileo/bsp/docker
```
This creates a container named 'contiki-galileo-build' based on Ubuntu and
installs development tools in the container.
The build commands shown below can be run within the newly-created container. To
obtain a shell, run the following command in PowerShell from the base directory
of the repository.
```
docker run -t -i -v ${Pwd}:/contiki contiki-galileo-build
```
This command mounts the current directory and its subdirectories at the path
'/contiki' within the container. Changes to those files in the container are
visible to the host and vice versa. However, changes to the container
filesystem are not automatically persisted when the container is stopped.
The containerized build environment does not currently support building the Grub
bootloader nor debugging using the instructions in this document.
See the Docker Overview for more information about working with containers [7].

### Prepare SDcard
The instructions in this section are for a native Linux development environment,
so equivalent operations should be substituted when using some other environment
(e.g. Windows Explorer can be used to perform equivalent operations when using
Docker on Windows as a development environment).
Mount the sdcard in directory /mnt/sdcard.
Create UEFI boot directory:

$ mkdir -p /mnt/sdcard/efi/boot

No additional steps should be required to boot a Contiki UEFI image.
