This patch series introduces the ability to save additional information
for the domain state and exposes this information in virsh domstate.
For example in the case of QEMU guest panic events, we can provide additional
information like the crash reason or register state of the domain. This
information usually gets logged in the domain log but for debugging it is
useful to have it accessible from the client. Therefore, let's introduce a new
public API function, virDomainGetStateParams, an extensible version of
virDomainGetState, which returns the complete state of the domain, including
newly introduced additional information.
Let's also extend virsh domstate and introduce a new parameter --info to show
the domain state, reason and additional information when available.
virsh domstate --info guest1
crashed (panicked: s390: core='1' psw-mask='0x1234000000000000' \
psw-addr='0x0000000000001234' reason='disabled-wait')

v1 -> v2:
* refactored the public API according to discussions to provide a
more machine-parsable interface
