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
```

When building some code against mimalloc with C inside Visual Studio
with ClangCL, the compiler complains about __GNUC__ being undefined.

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.
