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.

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

d9a0624529 Print current values of stat counters as well. 
For some reasons unknown to me the current values of stat counters are never printed.
This makes is quite hard to use printing during the debugging in the middle
of program run.

9c45221243 Do not use the same counter for warnings and errors. 
Warnings happen normally and could be safely ignored in the most cases,
however errors, if enabled, should not be ignored. Currently since warnings
and errors share the same counter we effectively stop showing errors after
16 warnings (which happen all the time).

Use different counters for errors and warnings.

1deea03bf1 On Darwin, using MADV_FREE_REUSABLE/MADV_FREE_REUSE. 
The former to notify the pages are available for other processes,
 the latter is needed for proper counting in case those pages where
tagged as reusable previously otherwise is a no-op, all for better
 RSS reporting for task_info apps.
