txr: fix --free-all crash due to atexit order.

The --free-all feature is broken. It is needed for confirming
lack of memory leaks during development. What breaks it is the
atexit call to run_load_hooks in eval.c, which occurs after
the atexit call to free_all in txr.c which blows everything
away.

* Makefile (tst/tests/019/load-hook.ok): Let's put --free-all
on this test case, because it has to with the load hooks.
Make no mistake though: everything crashes with --free-all,
not this test case specifically.

* txr.c (opt_free_all): New global variable.
(free_all): Free resources only if opt_free_all is true.
Lose the paranoid called flag.
(main): Register free_all with atexit before callilng init.
This ensures that it will be called after any atexit
handlers registered as part of init, like the one in sysif.c
and eval.c.
(txr_main): The --free-all option now just sets opt_free_all.

* txr.h (opt_free_all): Declared.
