keys to have _uint in their names, to match the routines that handle dissector tables with string keys. (Using _port can confuse people into thinking they're intended solely for use with TCP/UDP/etc. ports when, in fact, they work better for things such as Ethernet types, where the binding of particular values to particular protocols are a lot stronger.) svn path=/trunk/; revision=35224
