Libguestfs - Oct 2015 - Outline Rust bindings

Outline Rust bindings, obviously incomplete.

Attached is an example program showing how these bindings might be
used.  The most obvious thing is all the explicit error checking that
the caller must do (same as in C).  I'm not sure how natural that is,
but the alternatives seem to be lots of calls to either 'assert!'  or
'panic!' functions.

To try it out:

(1) Apply the patch.

(2) Copy attached main.rc into rust/src/

(3) Build libguestfs.

(4) Do:

  cd rust
  cargo build
  cargo run

virt-top is 'top' for virtual machines.  Tiny program with many
powerful monitoring features, net stats, disk stats, logging, etc.

Updated patch.  This one doesn't compile, with some kind of obscure
Rust error that I can't be bothered with right now.

Instructions in the previous message.

Rich.

virt-p2v converts physical machines to virtual machines.  Boot with a
live CD or over the network (PXE) and turn machines into KVM guests.
