  Increase the size of our thread stack on 64 bit processors.
  
  We were setting the stack size for each thread to 240KB regardless of
  architecture, which meant that in some scenarios we actually had less available
  stack space on 64 bit processors (pointers use 8 bytes instead of 4).  So now we
  calculate the stack size we reserve based on the platform's __WORDSIZE, which
  gives us:
  
       32 bit -> 240KB
       64 bit -> 496KB
      128 bit -> 1008KB (that's right, we're ready for 128 bit processors)
  
  Patch typed by me but written by several members of #asterisk-dev, including
  Kevin, Tilghman, and Qwell.
