5ee8f19bdd ENH: refine handling of DynamicList/DynamicField resizing
- previously had special resizing treatment for the corner case when
  the addressable size and the new capacity are identical. However,
  that particular approach (to minimize copying) meant that the exact
  deallocation size would likely be incorrect.
  Having the correct deallocation size becomes more important with
  alternative allocators.

  Introduce resize_copy() protected function to limit the number
  of elements copied during the resize.

ENH: provide DynamicList/DynamicField constructor with sizing

- allows fine-grained creation of a DynamicList/DynamicField with a
  given size/capacity without an initial value.

COMP: typo in code for DynamicList::push_back() with IndirectList

b8a4b7e80d ENH: additional 'nocopy' methods for List resize/reserve methods
- the size of a List often requires adjustment prior to an operation,
  but old values (if any) are not of interest and will be overwritten.

  In these cases can use the _nocopy versions to avoid additional memory
  overhead of the intermediate list and the copy/move overhead of
  retaining the old values (that we will subsequently discard anyhow).

  No equivalent for PtrList/UPtrList - this would be too fragile.

- add swap DynamicField with DynamicList

BUG: fixed Dynamic{Field,List} setCapacity corner case

- for the case when the newly requested capacity coincides with the
  current addressable size, the resize of the underlying list would have
  been bypassed - ie, the real capacity was not actually changed.

- remove (unused) PtrDynList setCapacity method as too fragile
