Re: [Libguestfs] [PATCH] Fix dependencies on generator.ml

This change adds an explicit dependency on generator.ml for every file it generates, except java files. Java is left for another time because it's considerably trickier. This fixes parallel make, and will automatically re-create generated files when make is run from any directory. It also changes the contents of the distribution tarball by including files created by rpcgen. It also fixes the problem which efad4f53 was targetting. Specifically, src/guestfs_protocol.(c|h) had an erroneous dependency on stamp-generator, and therefore generator.ml, despite not being directly created by it. This caused them to be recreated every time generator.ml ran rather than only when src/guestfs_protocol.x was updated, which cascaded into a daemon and therefore appliance update.
