For storage volume validation, we weren't consistent on whether to use VIR_FROM_NONE or VIR_FROM_STORAGE. Similar to previous patches, use a common macro to make it nicer. Furthermore, just as in commit 6e130ddc, the difference between VIR_IS_STORAGE_VOL and VIR_IS_CONNECTED_STORAGE_VOL is moot (due to reference counting, any valid volume must be tied to a valid connection). virStorageVolCreateXMLFrom allows cross-connection cloning, where the error is reported against the connection of the destination pool. * src/datatypes.h (virCheckStorageVolReturn) (virCheckStorageVolGoto): New macros. (VIR_IS_STORAGE_VOL, VIR_IS_CONNECTED_STORAGE_VOL): Drop unused macros. * src/libvirt.c: Use macro throughout. (virLibStorageVolError): Drop unused macro.

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.
