Fix logging for "strace -o FILE -ff test/threaded_execve" test case

Our logic which was deciding whether to print "<unfinished ...>"
thingy wasn't working properly for -ff case.

* defs.h: Group log generation-related declarations together.
Add a large comment which explains how it works.
Add declaration of line_ended() function.
* strace.c (line_ended): New function which sets up internal data
to indicate that previous line was finished.
(printleader): Change logic to fix log generation in -ff mode.
(newoutf): Make check for -ff mode consistent with other places.
(droptcb): Print "<detached ...>" if last line for this tcp wasn't finished.
(cleanup): Remove code to print "<unfinished ...>", printleader()
or detach() will do it instead.
(trace): Remove code to print "<unfinished ...>".
Add code which finishes threaded execve's incomplete line
with " <pid changed to PID ...>" message. Replace printing_tcp = NULL
followed by fflush() by line_ended() call.
* process.c (sys_exit): Call line_ended() to indicate that we finished priting.
* syscall.c (trace_syscall_exiting): Set printing_tcp to current tcp.
Call line_ended() to indicate that we finished priting.
Remove call to fflush(), it is done by line_ended() now.
