This patch makes sure that we terminate the event loop from the event
loop timer instead of directly in the process' exit handler. This allows
us to run the event loop an additional time to ensure that the SleepEx()
call on Windows is called and the data from stdout/stderr is delivered
to us.
Additionally we ensure that we don't try to read or write data from a
Unix process that have been terminated in the main loop, since its file
descriptors are closed at that time.

This patch changes our process_t's exit_callback to return a boolean
value. If the returned value is true, the process subsystem will call
process_free() on the given process_t.

This patch changes the slow process_t tests to use
run_main_loop_until_done() instead of do_main_loop() since
do_main_loop() initializes a lot of subsystem callbacks that we don't
need to run in our tests.

This patch disables fork()'ing of the slow process tests. This fixes the
tests on the MacOS and other kqueue() based platforms.
Without this patch the main loop exits eearly with EBADF as error.

This patch adds test cases for process_t which uses Tor's main loop.
This allows us to test that the callbacks are actually invoked by the
main loop when we expect them.
