Heap protect (#747)

Setting configENABLE_HEAP_PROTECTOR to 1 obfuscates heap
block pointers by XORing them with an application supplied
canary value. This obfuscation helps to catch heap corruption
should a heap buffer overflow occur.

This PR also adds heap bounds checking to heap_4 and heap_5.

This PR also adds some additional integer underflow checks.
