Create the given peer at the specified host using the given controller.
If the given controller is not running on the target host, it should find or create a controller at the target host and delegate creating the peer. Explicit delegation paths can be setup using 'GNUNET_TESTBED_controller_link'. If no explicit delegation path exists, a direct link with a subordinate controller is setup for the first delegated peer to a particular host; the subordinate controller is then destroyed once the last peer that was delegated to the remote host is stopped.
Creating the peer only creates the handle to manipulate and further configure the peer; use GNUNET_TESTBED_peer_start and GNUNET_TESTBED_peer_stop to actually start/stop the peer's processes.
Note that the given configuration will be adjusted by the controller to avoid port/path conflicts with other peers. The "final" configuration can be obtained using GNUNET_TESTBED_peer_get_information.

| void GNUNET_TESTBED_operation_done | ( | struct GNUNET_TESTBED_Operation * | operation | ) |
This function is used to signal that the event information (struct GNUNET_TESTBED_EventInformation) from an operation has been fully processed i.e.
if the event callback is ever called for this operation. If the event callback for this operation has not yet been called, calling this function cancels the operation, frees its resources and ensures the no event is generated with respect to this operation. Note that however cancelling an operation does NOT guarantee that the operation will be fully undone (or that nothing ever happened).
This function MUST be called for every operation to fully remove the operation from the operation queue. After calling this function, if operation is completed and its event information is of type GNUNET_TESTBED_ET_OPERATION_FINISHED, the 'op_result' becomes invalid (!).
If the operation is generated from GNUNET_TESTBED_service_connect() then calling this function on such as operation calls the disconnect adapter if the connect adapter was ever called.

Convenience method for running a "simple" test on the local system with a single call from 'main'.
