Ján Tomko 53531e16bf virsh: fix incorrect argument errors for long options
For long options, print:
* the option as specified by the user if it's unknown
* the canonical long option if its argument is not
  a number (and should be)

And for missing arguments, print both the short and
the long option name.
(Doing only one of those would require either parsing
argv ourselves or let getopt print the errors, since
we can't tell long and short options apart by optopt
or longindex)

https://bugzilla.redhat.com/show_bug.cgi?id=949373

Unsupported long option:

$ virsh --pm
Before:
error: unsupported option '-
After:
error: unsupported option '--pm'. See --help.

Missing parameter:

$ virsh --deb
Before:
error: option '-d' requires an argument
After:
error: option '-d'/'--debug' requires an argument

$ virsh -rd
Before:
error: option '-d' requires an argument
After:
error: option '-d'/'--debug' requires an argument

Non-numeric parameter:

$ virsh --deb duck
Before:
error: option -d takes a numeric argument
After:
error: option --debug takes a numeric argument

         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.
