Darwin: many fixes for OSX 10.13

Most of these changes are from Louis Brunner's GitHub repo.
The most imortant changes are to the memory space and to the code
related to getting the host filename during startup. This means
that when Valgrind crashes or hits an assert we now get a legible
host stacktrrace.

This also fixes none/tests/darwin/bug228343
