Merge remote-tracking branch 'gguowei/wp-703' into WP-703-wei
FindCallBack impl refinements

PendingOperation constructor now takes cancel function parameter, for
better information hiding. Don't use delete, garbage collection will take
case of unreferenced objects. Store rpc request instead of pendingOp in
callerCache. DOMError uses name instead of type property

Jira-issue: WP-703
findServices as instance function

Change findServices to be an instance function, so more variables can be
private inside the ServiceDiscovery.

Jira-issue: WP-703
More ServiceDiscovery tests

Add tests for PendingOperation, AbortError, TimeoutError.
