Switch from a rake-based build to a make-based build.
This commit beefs up the Makefile to do the build, instead of the Rakefile. It also removes from the Rakefile the dependency on rake_utils, which should mean it's ok to build in a schroot. The files are reorganised to make the Makefile rules more tractable, although the reorganisation reveals a problem with our current code organisation. The problem is that the proxy-specific code transitively depends on the server code via flexnbd.h, which has a circular dependency on the server and client structs. This should be broken in a future commit by separating the flexnbd struct into a shared config struct and server-specific parts, so that the server code can be moved into src/server to more accurately show the functional dependencies.
