096b9015dc Fix compatibility with GNU libstdc++ < 9
So far, mimalloc does not override the `nothrow` variants of the
`delete` operator because it assumes that their implementation in the
C++ standard library redirects to the default `delete` operators. This
is not the case for GNU libstdc++ < 9, where `std::free()` is called
directly.

This issue might be the cause for the crashes reported in #261.

Upstream bug: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68210

This commit ensures that the `nothrow` `delete` operators are properly
overridden by mimalloc.

0353fc38dd Allow overrides of MI_DEBUG memory constants
CPython and Windows CRT debug builds use different values for uninit,
freed, and padding bytes. Make ``MI_DEBUG_*`` constants conditional to
allow embedders to override the constants.

Windows dbgheap:

```
_bNoMansLandFill = 0xFD
_bDeadLandFill   = 0xDD
_bCleanLandFill  = 0xCD
```

Python memory debug

```
PYMEM_CLEANBYTE      0xCD
PYMEM_DEADBYTE       0xDD
PYMEM_FORBIDDENBYTE  0xFD
```

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.
