085e794a86 lib: Introduce event for tracking disk backing file write threshold
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.

862bea96d9 virsh: Use consistent naming for blkdeviotune options
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.

0289b8b2ba virsh: Display perf enabled/disabled message for set operations
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

Created a helper to print the messages - use the vshPrintExtra to
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.

b620bdee14 virsh: respect -q/--quiet more
Turn various vshPrint() informative messages into vshPrintExtra(), so
they are not printed when requesting the quiet mode; neither XML/info

Also change the expected outputs of the virsh-undefine test, since virsh

Some informative messages might still be converted (and thus silenced
when in quiet mode), but this is an improvements nonetheless.
