Add Vagrant configuration for creating a development VM

Vagrant is an application that automates creation and provisioning of a virtual
machine for development. The config here creates an Ubuntu 16.04 LTS machine,
updates it, downloads and installs the toolchains for sh, m68k and arm,
mingw-w64, SDL (for Windows simulators) and other packages needed for building
Rockbox.

It works fine for building a Windows simulator and compiling iPod classic
binaries. It should be possible to make the other build types, too.

MIPS toolchain fails to build, ARM-APP is not tested because the files download
very slow on my connection. Please test if it works for you, and let me know.

Quick start: download and install Vagrant and VirtualBox for your operating
system, make sure VT-x / AMD-V is enabled in your BIOS/EFI setup, open a
shell in rockbox/tools and input the command "vagrant up"
