566b2c51fc Add a missing #include 
This change fixes the "implicit declaration of function 'getenv'" warning.
Since stdlib.h is completely portable, as it is defined by the C standard,
we can safely include it unconditionally.

Change macOS mmap tag to fix conflict with IOAccelerator 
Tag 100 is assigned to "IOAccelerator" (the GPU driver stack on Apple silicon), which makes for confusing output when debugging.

To avoid conflicts, use a tag in the reserved application-specific range from 240–255 (inclusive).

All assigned tags: 94d3b45284/osfmk/mach/vm_statistics.h (L773-L775)

388d1aa9bd new Linux/Android option proposal. 
Allowing to disable transparent huge pages on Linux/Android, so
we avoid affecting the whole system (such as /sys/kernel/mm/transparent_hugepage/enabled).
