Paolo Bonzini points out that in my refactoring of the code for
virDomainMigrate(), I added a check for the return value from
virDomainMigratePerform().  The problem is that we don't want to
exit if we fail, we actually want to go on and do
virDomainMigrateFinish2() with a non-0 return code to clean things
up.  Remove the check.

While reproducing this issue, I also noticed that we wouldn't
always properly propagate an error message.  In particular, I
found that if you blocked off the migration ports (with iptables)
and then tried the migration, it would actually fail but we would
get no failure output from Qemu.  Therefore, we would think we
succeeded, and leave a huge mess behind us.  Execute the monitor
command "info migrate", and look for a failure string in there
as well.

The documentation for virNodeGetCellsFreeMemory claims the values
returned are in kilobytes, but that's actually wrong; the value
returned is actually in bytes.  Fix up the documentation to be
correct.

Currently the reference counting for connections is busted.  I
first noticed it while trying to use virConnectRef; it would
eventually cause a crash in the remote_internal driver, although
that was really just a victim.  Really, we should only call the
close callbacks on the methods when the references drop to 0.  To
accomplish this, move all of the close callbacks into
virUnrefConnect (since there are lots of internal users of that
function), and arrange for virConnectClose to call that.

V2: Make sure to drop the connection lock before we call the close
    callbacks, otherwise we could deadlock the daemon
V3: Fix up a crash when we got an error from one of the drivers

Re-factor virDomainMigrate to split out the version 1 and version 2
protocols into their own functions.  In reality, the two versions share
very little in common, so forcing them together in the same function was
just confusing.  This will also make adding tunnelled migration easier.

Do the check in libvirt.c, to save drivers from the burden. This changes
behavior slightly in the qemu driver: we no longer explictly error if
passed an empty string. An error will still be thrown when the device
lookup fails.

Features supported:
- Connects to HMC/VIOS or IVM systems.
- Life cycle commands (resume and shutdown).
- dumpxml
- 'list' and 'list --all'

What is being implemented:
- better and centralized control for UUID
- definexml
- CPU management commands

  src/domain_conf.[ch] src/libvirt.c src/virterror.c: glue the driver

We need to store things like device names and PCI slot numbers in the
qemu domain state file so that we don't lose that information on
libvirtd restart. Add a flag to indicate that this information should
be parsed or formatted.

Make bit 16 and above of the flags bitmask for internal use only and
consume the first bit for this new status flag.

built-in TODO list for each driver.  Also rip out the internal getURI method;
it is never used by any of the drivers, and was buggy to boot.
