Improve Darwin framework APIs to follow Objective-C conventions better.
Browse files Browse the repository at this point in the history 
Specific changes:

1) Rename Payload structs to Params structs.
2) For commands with no fields, have the name be fooWithCompletionHandler and
   no params struct.
3) For commands with only optional fields, allow the params struct to be nil.
4) Rename "responseHandler" to "completionHandler" so that we get the
   behavior described in
