Fixes startup of guest's with sourceless cdrom devices.

Patch from Cole Robinson originally posted here:

  https://bugzilla.redhat.com/499569

but never sent upstream.
Signed-off-by: NMark McLoughlin <markmc@redhat.com>

As pointed out by Tim Waugh here:

  https://bugzilla.redhat.com/507555

We shouldn't bother trying to set the context of a file if it already
matches what we want.

(Fixed to use STREQ() and not use tabs, as pointed out by danpb)

  driver compilation issues, patch by Javier Fontan and remove
  some tabs in format strings
daniel

If using a custom test driver, storage pool file parsing was broken, and
storage volume parsing was never implemented. Fix these issues, and add
some examples in docs/

The storage driver arranges its parsing routines in a way that make them
difficult to use in the test driver for non-default file parsing. This
refactoring moves things to be consistent with the way domain_conf and
network_conf do things.

If specifying a custom test driver, virtual networks were not 'activated'
on driver init. This differs from the behavior of domains and storage pools,
so fix it. Also improve a couple error messages in that area.

virEnumFromString doesn't check for a NULL string, and will segfault if
passed one. Lots of calling code protects against this, but at least
/pool/@type parsing does not.

Currently, 'info' will always report that mem = max mem. Make sure we
actually return the correct mem value.

CreateXMLFrom changes accidentally caused all raw volume creation to be
fully allocated (as though allocation == capacity). Fix this.

Also force CreateXMLFrom to maintain the previous behavior: sparseness
should still be maintained since we search for holes when copying, and the
clone behavior hasn't been tested with anything but the broken behavior.

The ID of the existing VM was being unconditionally set to -1, which was
upsetting virt-manager.
