Design block-based VFD and draft RFC

Informed from Silo's blockbased VFD that met with great success on Dawn, develop the equivalent, HDF5built-in VFD for HDF5. Some of the things silo's blockbased VFD does is to get around various bugs in the way upper layers of HDF5 were/are interacting with the VFD layer. The issues encountered there need to be discussed, tests demonstrating the issues on HDF51.8.4 need to be put together to demonstrate the problem(s).

Description:
Informed from Silo's blockbased VFD that met with great success on Dawn, develop the equivalent, HDF5built-in VFD for HDF5. Some of the things silo's blockbased VFD does is to get around various bugs in the way upper layers of HDF5 were/are interacting with the VFD layer. The issues encountered there need to be discussed, tests demonstrating the issues on HDF51.8.4 need to be put together to demonstrate the problem(s).

Comments:

Start by studying Silo's existing block-based VFD and the HDF5 VFD layer, then reproduce the reported upper-layer interaction issues against HDF5 1.8.4. The issue names no files or existing tests, so locate the relevant VFD and test entry points before drafting the RFC. Done means documented reproductions, agreed design, and a draft RFC for a built-in block-based VFD.
