John Baldwin 31174518d2 Use uintptr_t instead of register_t * for the stack base.
- Use ustringp for the location of the argv and environment strings
  and allow destp to travel further down the stack for the stackgap
  and auxv regions.
- Update the Linux copyout_strings variants to move destp down the
  stack as was done for the native ABIs in r263349.
- Stop allocating a space for a stack gap in the Linux ABIs.  This
  used to hold translated system call arguments, but hasn't been used
  since r159992.
