a4ed63d127 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.

559688ec64 Suppress warning about unnamed struct
This prevents MSVC complaining with

	warning C4201: nonstandard extension used: nameless struct/union

The struct might seem unnecessary to the occasional reader (it did seem
so to this commit's author), but it is not! It is required to align the
fields to a boundary, which is verified by the test suite. Removing that
"unnecessary" `struct` results in this failure:

1: Test command: mimalloc-test-api
[...]
1: test: malloc-zero...  mimalloc: assertion failed: at src/page.c:591, mi_page_init
1:   assertion: "!mi_page_has_aligned(page)"

e747a6f3a6 Use unsigned for bit-field variables
It is actually non-standard to use `bool` with a bit-field quantifier,
and VS 2019 complains about this.
