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.
- This hides dict_opt_c in summary.c. It also gets rid of the global
variable current_time_spent--instead, the information is passed via
a function argument in a struct timedelta (so that we never confuse
absolute time with relative). callstack_element.time_spent was renamed
to .enter_time, as that is what it has always been.
