This was listed as a bug, and was immediatelly picked the static
analyzer anyway, this is very likely the cause for the
migration-cancel-crash bug.

We were calculating the wrong number of words per byte in the first
place, and then passing the number of *words* to malloc, which expects
the number of *bytes*.
Fix both errors
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.
