DHCPMessage: support DHCP option 'vendor specific info'
This adds the support for DHCP option 'vendor specific
information'.
The information is an opaque object of n bytes, presumably
interpreted by vendor-specific code on the clients and
servers.
While there, I add the corresonding ByteArray parser in class
DHCPOptionParser.
