13de1920ae Rename _os_random_weak to _mi_os_random_weak 
The ``_os_random_weak`` function is the only non-static function
besides ``_ZSt15get_new_handlerv`` that is not prefixed with ``mi`` or
``_mi``.

The discrepancy was discovered by CPython's smelly script. The checker
looks for exported symbols that don't have well-defined prefixes.

7c73e3996d Fix strict function prototype warnings 
Fix warning ``warning: function declaration isn’t a prototype`` when
building mimalloc with ``-Wstrict-prototypes`` flag. In C argumentless
functions should be declared as ``func(void)``.

Reproducer:
```shell
$ cmake ../.. -DCMAKE_C_FLAGS="-Wstrict-prototypes"
$ make VERBOSE=1
```

Fix thread ID getter on Android ARM/AArch64

3402c6cc3f Revise the use of macOS predefined macro 
Quoted from "Porting UNIX/Linux Applications to OS X,"[1]
* macro __MACH__ is defined if Mach system calls are supported;
* macro __APPLE__ is defined in any Apple computer.

__MACH__ is not specific to macOS since GNU/Hurd runs on a Mach-based
microkernel (gnumach) [2]. __MACH__ is defined by the compiler,
leading to potential confusions. The solution is just changing the
checked identifier (i.e. __APPLE__), so it is really used only on
macOS.

Fix thread ID getter on Android ARM/AArch64 
Android's Bionic libc stores the thread ID in TLS slot 1 instead of 0
on 32-bit ARM and AArch64. Slot 0 contains a pointer to the ELF DTV
(Dynamic Thread Vector) instead, which is constant for each loaded DSO.

Because mimalloc uses the thread ID to determine whether operations are
thread-local or cross-thread (atomic), all threads having the same ID
causes internal data structures to get corrupted quickly when multiple
threads are using the allocator:

mimalloc: assertion failed: at "external/mimalloc/src/page.c":563, mi_page_extend_free
  assertion: "page->local_free == NULL"
mimalloc: assertion failed: at "external/mimalloc/src/page.c":74, mi_page_is_valid_init
  assertion: "page->used <= page->capacity"
mimalloc: assertion failed: at "external/mimalloc/src/page.c":100, mi_page_is_valid_init
  assertion: "page->used + free_count == page->capacity"
mimalloc: assertion failed: at "external/mimalloc/src/page.c":74, mi_page_is_valid_init
  assertion: "page->used <= page->capacity"

Add support for Android's alternate TLS layout to fix the crashes in
multi-threaded use cases.

Fixes #376.

e6c2fd44fc DragonFly support fix (for 5.8.x and forward). 
The pthread slot approach is somewhat buggy (pretty visible
 with the stress unit test which segfault more or less randomly,
 but the stats never show up).
Using the default approach instead, the test passes eventough
 it s relatively slow (e.g 1.5 sec on FreeBSD vs 4.5 on DragonFly with same
 machine).
