psLib prevents the use of malloc, realloc, calloc, & free

[jhoblitt]

sysUtils/psMemory.h uses the GCC poison pragma on malloc, realloc, calloc, &
free. This causes serious interoperability issues with 3rd party code.

The example below will not compile.

#include <pslib.h>
#include <stdlib.h>

int main () {

int *foo;

foo = malloc(sizeof(foo));

}

This was actually specified by the SDRS. The SDRS has been updated to specifiy
that this behavior should be kept internal to psLib unless requested by the
client code.
