Adresses pr #165 and issue #164 by @colesbury:
...
On Mac OS, the thread-local _mi_default_heap may get reset before
_mi_thread_done is called, leaking the default heap on non-main threads.
Now the current default heap is also stored in mi_pthread_key (or mi_fls_key
on Windows). The _mi_thread_done function is called with this value.

Avoid compiler warning when casting the result of GetProcAddress()
...
It is most unfortunate that the return type of `GetProcAddress()` is
`FARPROC` (which is essentially `intptr_t(*)(void)): this type cannot
be cast by GCC without warnings to anything but the generic function
pointer type `void(*)(void)`.
Let's work around that.

Quite a few functions are declared with that attribute, and VS 2019
