[libvirt] [PATCH 0/8] Cleanup improper VIR_ERR_NO_SUPPORT use

[Osier Yang]

Error code VIR_ERR_NO_SUPPORT will be translated to "this function
is not supported by the connection driver", however, it's used
across the whole projects, this patch is trying to cleanup all
the improper use in the source tree.

The modification can be grouped to 3 following groups:

1) The error intends to tell user it's invalid operation.

     s/VIR_ERR_NO_SUPPORT/VIR_ERR_OPERATION_INVALID.

2) The error intends to tell the configuration of domain
   is not supported.

     s/VIR_ERR_NO_SUPPORT/VIR_ERR_CONFIG_UNSUPPORTED/

3) The error intends to tell the function is not implemented
   on some platform.

     * s/VIR_ERR_NO_SUPPORT/VIR_ERR_OPERATION_INVALID/
     * and add error strings

     e.g.

static int
lxcDomainInterfaceStats(virDomainPtr dom,
                        const char *path ATTRIBUTE_UNUSED,
                        struct _virDomainInterfaceStats *stats ATTRIBUTE_UNUSED)
    -lxcError(VIR_ERR_NO_SUPPORT, __FUNCTION__);
    +lxcError(VIR_ERR_OPERATION_INVALID, "%s",
    +         _("interface stats not implemented on this platform"));
    return -1;
}
