re: https://github.com/Unidata/netcdf-c/issues/2294 Ed Hartnett suggested that the netcdf library installation process be extended to install the standard filters into a user specified location. The user can then set HDF5_PLUGIN_PATH to that location. This PR provides that capability using: ```` configure option: --with-plugin-dir=<absolute directory path> cmake option: -DPLUGIN_INSTALL_DIR=<absolute directory path> ```` Currently, the following plugins are always installed, if available: bzip2, zstd, blosc. If NCZarr is enabled, then additional plugins are installed: fletcher32, shuffle, deflate, szip. Additionally, the necessary codec support is installed for each of the above filters that is installed. ## Changes: 1. Cleanup handling of built-in bzip2. 2. Add documentation to docs/filters.md 3. Re-factor the NCZarr codec libraries 4. Add a test, although it can only be exercised after the library is installed, so it cannot be used during normal testing. 5. Cleanup use of HDF5_PLUGIN_PATH in the filter test cases.

* Dynamically loaded filter plugin for HDF5 blosc filter.

* Header file
|
|
* -----------
|
|
*
|
|
* This provides dynamically loaded HDF5 filter functionality (introduced
|
|
* in HDF5-1.8.11, May 2013) to the blosc HDF5 filter.
|
|
*
|
|
* Usage: compile as a shared library and install either to the default
|
|
* search location for HDF5 filter plugins (on Linux
|
|
* /usr/local/hdf5/lib/plugin) or to a location pointed to by the
|
|
* HDF5_PLUGIN_PATH environment variable.
