Nathan Froyd dbc53de3d9 Bug 1451363 - part 5 - remove ProtocolName virtual function; r=mccr8
ProtocolName() is only used for producing error messages and annotating
crash reports.  But examining actual crash reports that would have used
the result of ProtocolName() indicates that we can always tell what the
erroring protocol is due to the stack backtrace.  So having this virtual
function around just provides duplicate information, and it takes up too
much space in the vtable besides.  Let's get rid of it.
