[libvirt] [libvirt-php] Add lookup function for pool & volume

[Michal Novotny]

Hi Lyre,

> +		set_error ("Cannot find storage pool" TSRMLS_CC);


This is being set by the function itself and caught using the
catch_error() so please avoid this line in v2 of the patch.


> +	volume=virStorageVolLookupByPath (conn->conn,name);
> +	if (volume==NULL)
> +	{
> +		set_error ("Cannot find volume");
> +		RETURN_FALSE;
> +	}


Same here.

Thanks,
Michal
