Refactor unit test macros and tor_free_all() logic a bit so as to make it easier to free memory on failing tests, in order to suppress scanner warnings and to make dmalloc() usable with tests.

Replace the dummy-use var in SMARTLIST_FOREACH_END() with one that is less likely to confuse analysis tools into thinking we do use after free.  Arguably, (void)x should count as use in suppressing unused variable warnings, but not in generating hey-you-used-a-variable warnings.  Arguably, though, it shouldn't.

It is probably some kind of misdeed to say for (i=0;i<2;++i) { A=i?x:y; foo(bar(A)); } rather than foo(bar(x)); foo(bar(y)); .  Also, it can confuse tools.

Add a lockfile to the Tor data directory to avoid situations where two Tors start with the same datadir, or where a --list-fingerprints races with a server to create keys, or such.

If not enough of our entry guards are available so we add a new
one, we might use the new one even if it overlapped with the
current circuit's exit relay (or its family). Anonymity bugfix
pointed out by rovv.
