I have rebased and tidied up the patches, fixing a few spelling
mistakes, but they are broadly the same as before.  I also ran all the
tests, which pass.

As with the previous versions, this makes a change to the API, where
you can no longer pass a handle between threads and expect
guestfs_last_error() to work.  I'm somewhat more sanguine about this
change, since using the API like that is abstruse and no one should be
expecting that to have worked.
