unsigned long is the base type for buffer positions now

* This allows handling files >64kb even on 16-bit DOS.
* A few flags fields could be squashed into bitfields.
* The buffer overview (0EB) has been adapted for DOS.
  We can only show the total amount of allocated
  memory (as by tecmem.c) for the time being.
  Unfortunately, we don't have a total amount of available
  memory since _memavl() is for small data models and
  the sbrk() apparently doesn't grow.
