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
```

0f57425f80 Distinguish SI and Binary Prefixes 
SI prefixes [the decimal prefixes] refer strictly to powers of 10. They
should not be used to indicate powers of 2. e.g., one kilobit
represents 1000 bits instead of 1024 bits. IEC 60027‐2 symbols are
formed adding a "i" to the SI symbol (e.g. G + i = Gi).

765fc9c0ca Unify statistic collection: 
- For MI_STAT == 0 no allocation stats are collected
  - For MI_STAT == 1 only aggregated values (across normal, large and huge heaps) are collected
  - For MI_STAT == 1 separate per-bin collection for normal heap is done as well

079b886feb Add cmake option to specify whether warnings / errors are enabled by default. 
Currently warnings / errors are enabled by default in debug build.
Otherwise they could be enabled only via environmental variable or
API option call. Add possibility to specify the default during the
build time. This simplifies e.g. integration of the library into
bigger projects as no source changes would be required.
