Forward-ported staplog.c crash support (PR 10644).
* staplog.c (get_rchan): Separated original relayfs code and current
relayfs code.
(get_rchan_buf): Ditto.
(output_cpu_logs): Ditto.
(get_rchan_addr): Handles original relayfs code detection.
(setup_global_data): Looks for '_stp_relay_data' structure instead of
'_stp_utt' structure.
(open_output_file): Improved error message.
* runtime/transport/relay_v2.c: Rearranged struct _stp_relay_data_type to
make things a bit easier for staplog.c.
* runtime/transport/relayfs.c: Ditto
