Fix segfaults when parsing bdiff hunks in mpatch.decode() and .patchedsize()

- fix off by 11 when checking if there are more hunks (found by Maris Fogels)
- bail out if start is greater than end
- check if new hunk starts after start/end/len block of current hunk as
  the pointer can wrap around on very large values, reproducible with
  import mpatch; mpatch.patchedsize(12, 'x'*12)
