unix port displays incorrect addresses

[mattytrentini]

mem_usage_render.py always renders address lines with 0x800 increments - correct for 32bit systems but incorrect for 64 bit systems, most predominately the unix port. On these ports, the correct increment is 0x1000.

(Note that mem_dump.py outputs lines correctly as 0x400 and 0x800 for 32/64 bit systems respectively. But mem_usage_render.py combines two lines when rendering to make the output more compact. So the address increment in the render output should be double that of the address increment observed in the memory dump log.)

This would need to be changed in mem_usage_parser/frame_parser.py:75, currently:

addr = len(body) * 0x400 * MULT

Whether it's a 32 or 64 bit system would need to be included in the output of mem_dump.py. It can be determined with the following snippet:

>>> # unix port
>>> import struct 
>>> struct.calcsize("P") * 8
64
