add HIL_STATE message handler and publish to uORB

add missing break

uorb topics generator: add multi-topics to the list of all topics

topic names with '# TOPICS <name>' were previously not in orb_get_topics().
This means the logger could not find them.

Affects for example actuator_controls_0.

px_generate_uorb_topic_files.py: add multitopics to generate_topics_list_file_from_files method

switch simulated attitude to new topic: vehicle_attitude_groundtruth

logger: add input_rc topic. needed for web plotting

input_rc.msg: remove timestamp_publication, use timestamp instead

mixer.cpp: warnx -> PX4_ERR

logger: initialize timer_call to 0 (hrt_call_every reads some fields)

position_setpoint_triplet topic: set the timestamp when publishing

px_generate_uorb_topic_files.py: add multitopics to generate_topics_list_file_from_files method

add vehicle_attitude_groundtruth to default topics

change to hil_state_quaternion
