Mark Olesen 96c9bf8615 ENH: add List::resize_unsafe(label)
- changes the addressed list size without affecting list allocation.
  Can be useful for the following type of coding pattern:

  - pre-allocate a List with some max content length
  - populate with some content (likely not the entire pre-allocated size)
  - truncate the list to the length of valid content
  - process the List
  - discard the List

  Since the List is being discarded, using resize_unsafe() instead of
  resize() avoids an additional allocation with the new size and
  copying/moving of the elements.

  This programming pattern can also be used when the List is being
  returned from a subroutine, and carrying about a bit of unused memory
  is less important than avoiding reallocation + copy/move.

  If used improperly, it can obviously result in addressing into
  unmanaged memory regions (ie, 'unsafe').
