Update add_to_bridge shell function to read the vlan parameter from xenstore and set the bridge VLAN configuration for the VID. Add additional helper functions to parse the vlan specification, which consists of one or more of the following: a) single VLAN (e.g. 10). b) contiguous range of VLANs (e.g. 10-15). c) discontiguous range with base, increment and count (e.g. 100+10x9 which gives VLAN IDs 100, 110, ... 190). A single VLAN can be suffixed with "p" to indicate the PVID, or "u" to indicate untagged. A range of VLANs can be suffixed with "u" to indicate untagged. A complex example would be: vlan=1p/10-15/20-25u This capability requires the iproute2 bridge command to be installed. An error will be generated if the vlan parameter is set and the bridge command is not available.
