Thomas Preud'homme 0125e45595 Port pstack to amd64 architecture 
This patch is an effort to port pstack to other architectures. So far
only amd64 is supported and there is probably still some issues in the
architecture independant code (endianness, integer range, per
architecture frame browsing, …).

Thomas Preud'homme 8d28686a86 Fix incorrect error checking 
pstack uses errno to check errors in lots of case which is wrong. According

an error. This patch fixes all the errno check errors.

no name. This tiny patch makes pstack ignore those objects.
