Eric Blake e064205936 conf: avoid NULL deref for pmsuspended domain state 
While working with a pmsuspend vs. snapshot issue, I noticed that
the state file in /var/run/libvirt/qemu/dom.xml contained a rather
suspicious "(null)" string, which does not round-trip well through
a libvirtd restart.  Had I been on a platform other than glibc
where printf("%s",NULL) crashes instead of printing (null), we might
have noticed the problem much sooner.

And in fixing that problem, I also noticed that we had several
missing states, because we were #defining several *_LAST names
to a value _different_ than what they were already given as enums
in libvirt.h.  Yuck.  I got rid of default: labels in the case
statements, because they get in the way of gcc's -Wswitch helping
us ensure we cover all enum values.

* src/conf/domain_conf.c (virDomainStateReasonToString)
(virDomainStateReasonFromString): Fill in missing domain states;
rewrite case statement to let compiler enforce checking.
(VIR_DOMAIN_NOSTATE_LAST, VIR_DOMAIN_RUNNING_LAST)
(VIR_DOMAIN_BLOCKED_LAST, VIR_DOMAIN_PAUSED_LAST)
(VIR_DOMAIN_SHUTDOWN_LAST, VIR_DOMAIN_SHUTOFF_LAST)
(VIR_DOMAIN_CRASHED_LAST): Drop dead defines.
(VIR_DOMAIN_PMSUSPENDED_LAST): Drop dead define.
(virDomainPMSuspendedReason): Add missing enum function.
(virDomainRunningReason, virDomainPausedReason): Add missing enum
value.
* src/conf/domain_conf.h (virDomainPMSuspendedReason): Declare
missing functions.
* src/libvirt_private.syms (domain_conf.h): Export them.

         LibVirt : simple API for virtualization

  Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
