Purpose:
HDF5 now supports SZIP with no encoder.

Description:
SZIP can be configured to have both encoder and decoder or just to have the decoder.  HDF5 can now query the configuration of any filter, and will throw errors if users try to write using a filter with encoding disabled.

Solution:
Added H5Zget_filter_info function, changed API for H5Pget_filter and H5P_get_filter_by_id.  See SZIP RFC.

Platforms tested:
Copper (fortran, C++, parallel), Sleipnir (C++), Arabica (fortran, C++), Verbena (fortran, C++)
