7d1c15b07a Fix two bugs in mirroring.
First, Leaving off the source address caused a segfault in the
command-sending process because there was no NULL check on the ARGV
entry.

Second, while the migration thread sent a signal to the server to close
on successful completion, it didn't wait until the close actually
happened before releasing the IO lock.  This meant that any client
thread waiting on that IO lock could have a read or a write queued up
which could succeed despite the server shutdown.  This would have meant
dataloss as the guest would see a successful write to the wrong instance
of the file.  This patch adds a noddy serve_wait_for_close() function
which the mirror_runner calls to ensure that any clients will reject
operations they're waiting to complete.

This patch also adds a simple scenario test for migration, and fixes
TempFileWriter#read_original.

b546539ab8 Rewrote error & log functions to be more general, use longjmp to get out of
trouble and into predictable cleanup functions (one for each of serve,
client & control contexts).  We use 'fatal' to mean 'kill the thread' and
'error' to mean 'don't kill the thread', assuming some recovery action,
except I don't use error anywhere yet.

8691533d88 Added hopeful default path to find rake_utils, turned undefined function
warnings into errors, and added expensive header scanning to .c->.o rule to
ensure changes to .h files cause recompiles as you'd expect.
