The command "info migrate" of qemu outputs the dirty-pages-rate during
migration, but page size is different in different architectures. So
page size should be output to calculate dirty pages in bytes.
Page size is already implemented with commit
030ce1f8612215fcbe9d353dfeaeb2937f8e3f94 in qemu.
Now Implement the counter-part in libvirt.

Requesting an automated switch to a post-copy migration (using
--timeout-postcopy) without actually enabling post-copy migration (using
--postcopy) doesn't really do anything. Let's make this dependency
explicit to avoid unexpected behavior.

This commit adds the unix socket URL support to 'domdisplay' command.
Before, even if an user was using unix socket to define a spice graphics,
the command 'domdisplay' showed that the settings were not supported. Now,
the command shows the proper URL: spice+unix://foo/bar.sock.
Settings:
<graphics type='vnc' port='-1' autoport='yes' listen='127.0.0.1'>
<listen type='address' address='127.0.0.1'/>
</graphics>
<graphics type='spice'>
<listen type='socket' socket='/tmp/spice.sock'/>
</graphics>
Before:
virsh # domdisplay --all Windows7
vnc://127.0.0.1:0
After:
virsh # domdisplay --all Windows7
vnc://127.0.0.1:0
spice+unix:///tmp/spice.sock

While looking to implement a migrate-getmaxdowntime command (coming),
I noticed that the setmaxdowntime is incorrectly looking at its
parameter as a signed longlong. Not sure how that got past gcc, but
here's a simple patch to make the command line parsing and the parameter to
the worker functions all have the correct (unsigned) type.

QEMU will likely report the details of it shutting down, particularly
whether the shutdown was initiated by the guest or host. We should
forward that information along, at least for shutdown events. Reset
has that as well, however that is not a lifecycle event and would add
extra constants that might not be used. It can be added later on.

virt-install and virt-manager both default to explicitly setting
"io='native'" in the disk "driver" tag. virsh, however, does not and also
does not provide an option to specify that setting at all. As a result,
disks use a different IO mechanism (the default, "threads") when attached
post-setup using virsh. Adding this option allows users to keep disk
performance consistent for disks attached at install, and those attached
afterward.
The parameter is reported by virDomainGetJobStats API and
VIR_DOMAIN_EVENT_ID_JOB_COMPLETED event and it can be used to identify
the operation (migration, snapshot, ...) to which the reported
statistics belong.

virshCommandOptDomainBy to the helper file. Additionally turn the
virshCommandOptDomainBy macro into a function.

When using thin provisioning, management tools need to resize the disk
in certain cases. To avoid having them to poll disk usage introduce an
event which will be fired when a given offset of the storage is written
by the hypervisor. Together with the API which will be added later, it
will allow registering thresholds for given storage backing volumes and
this event will then notify management if the threshold is exceeded.
All options started with underscores, but we switched them to dashes
later on, making the style consistent. The latest addition, however,
did not respect that, so let's change that as well. It is tempting to
just change the name instead of adding alias, especially since nobody
ever used it, which we know thanks to the fact that it didn't work.

When setting perf events, the enabled/disabled perf events are not
listed. Since we know which events were changed it's possible to
print out the values on successful set, such as :
virsh perf Domain --enable instructions --disable cache_misses
instructions : enabled
cache_misses : disabled

adhere to the --quiet|-q option being set by some script. This will
cause the get code to print nothing, but will return success/failure.
