Added timer data flushing and overwrite handling to the ring_buffer transport.
* buildrun.cxx (compile_pass): Checks for ring_buffer api change.
* runtime/autoconf-ring_buffer-flags.c: New file.
* runtime/transport/ring_buffer.c (tracing_wait_pipe): No longer
schedules, just returns. The timer function will handle it later.
(_stp_data_write_reserve): Handles ring_buffer api change. Added
overwrite processing. If we're full, delete an event to make room.
(_stp_data_write_commit): Handles ring_buffer api change.
(__stp_relay_wakeup_timer): New function.
(__stp_relay_timer_start): Ditto.
(__stp_relay_timer_stop): Ditto.
(_stp_transport_data_fs_start): Calls __stp_relay_timer_start().
(_stp_transport_data_fs_stop): Calls __stp_relay_timer_stop().
(_stp_transport_data_fs_overwrite): Sets overwrite flag.
