From 0cf4ab66e9927e101a51dd9fa9adc6c8dc56b5e7 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Consider exec and exit events an end of outstanding calls
- This cleans up a lot of stuff. The actual substance is addition of
account_current_callstack in handle_event.c (which however uses
those cleaned-up interfaces).
- trace-exec.exp was extended to check that the exec syscall can be
seen in -c output. That's one of the symptoms of what this fixes.
