We used to rely on out-of-tree git clones to be prepared by the user.
This commit changes the system to make sure we clone all git repos
we depend upon into the 'deps' folder, and then setup the symlinks
to that folder. As a result, we should be able to support
self-contained builds using the makefiles in this repo.
Their format is simply too complex to be used with the automatic RAW
encoder/decoder. Let's implement it by hand, using the automatic
coder whenever possible.
