Refactored how pieces and extents are handled.

Refactoring the way VTK goes between piece and structured
extents. Before, extent translators were used when the pipeline
moved from structured to unstructured data converting piece
request to extent request. This caused many problems with filters
that altered extents, mainly a lot of redundant IO due to
repartitioning of different extents. This became extremely
cumbersome to manage when running distributed. The new behavior
pushes the extent translation all to way to the readers and
only when readers are able to read a subset. This works much
better. The only downside is that filters need to be able to
handle data extents different than update extents. Most filters
can do this but many imaging filters cannot. Those that are
needed in parallel will have to be updated.

As part of this work, I also removed MAXIMUM_NUMBER_OF_PIECES
and added CAN_HANDLE_PIECE_REQUEST. MAXIMUM_NUMBER_OF_PIECES had
reduced to being a boolean. 1 for serial sources, -1 for parallel
sources. I removed it and added a CAN_HANDLE_PIECE_REQUEST instead.
This key, produced by a source, tells the executive that a source is
able to handle piece request. It is a source only key produced in
RequestInformation and is not propagated downstream. If this key is
not present, the executive will only execute the source for piece 0
to produce the entire data. It is then up to the user to add a filter
that splits the data for other piece requests. The only exception to
this is when CAN_PRODUCE_SUB_EXTENT is present, in which case the
executive will split using an extent translator AT THE source - not
downstream.

Update the XML readers and writers to work with pipeline changes.

The XML readers and writers, both parallel and serial, now work
with the pipeline changes. Now, all writers work with pieces
even though the structured ones can handle asking for a sub-
extent.

Change-Id: I9f757ba12a3b9fb84e141506dacadad608eb8b99
Cleaned up and fixed transmit filters for structured data.

Change-Id: I7e5c55259159752882c8ae056e08f9bec12b3c02
Fixed bug in send structured data.

The origin was not offset properly in cases where extent
had to be adjusted. This is all due to the fact that the
legacy writer always writes extents starting at 0.

Change-Id: Id37f21d7c99d2ecdf6285d2870bf87e10b534a7a
Fixed legacy parallel reader and writer.

To work with the new pipeline changes.

BUG: Was using array of wrong size.

Was trying to read the extent into an array of size 3 instead
of 6. Doh!

Fixed compiler warnings.

Changed synchronized templates class for new pipeline behavior.

Note that this change slightly breaks backward compatibility.
The filter now processes all points even if they are on a ghost
region. This means that this filter will produce ghost polygons
that need to be stripped downstream. This is in line with the
"filters should work with what they have" attitude the new
changes enforce. This makes pipeline and filter logic much
simpler.

Removed unused keys.

Moved key.

It made more sense to have both CAN_PRODUCE_SUB_EXTENT and
CAN_HANDLE_PIECE_REQUEST in vtkAlgorithm.

Cleaned up extent translators.

- Removed unused extent translator subclasses
- Removed unnecessary refereces to the extent translator
- Moved extent translator into Common/ExecutionModel

Fixed multiple issues with resample/probe filters.

The main issue was in asking the right update extent from
the input. Also fixed a number of bugs in the resample filter.
