cb40ad3a90 Continued un-exporting of symbols; renames 
- Unexport consts, types, vars, etc.
- Rename Conntracker (interface) to FlowWalker, to match its definition.
- Rename conntracker (type) to conntrackWalker, to match the interface.
- Move conntrack_test.go to conntrack_internal_test.go and package endpoint

6ae5077515 Un-export NATMapper 
Lots of TODOs to clean up...

36ce1089f4 Don't export reverseResolver 
It's only used within package endpoint, so it shouldn't be exported.
That means resolver_test becomes resolver_internal_test, and with the
previous change to the fixture, we can avoid the dot-import.

Also, update method names to reflect it's an unexported type.

32a57e63db probe/endpoint: NATMapper missed an edge case 
NATMapper can be created with a nil Conntracker if
ConntrackerModulePresent is false, e.g. on Darwin.
Check for that in ApplyNAT.
