-----------
Implement IPC message name logging on receive
rdar://167685378
https://bugs.webkit.org/show_bug.cgi?id=305043
Reviewed by Kimmo Kinnunen.
This patch implements logging for IPC message names in a process-wide,
append-only ring buffer on message receive.
The contents of this buffer can be read from a crashed process to
understand the flow of messages that might have caused this crash.
