This relies on the HDF5 capability to
dynamically load compression filters.
Note that a compression filter is just
a subcase of filters.
The primary user-visible changes are as follows:
1. Add a standard header "netcdf_filter.h" that defines
the necessary API extensions
2. Modify ncgen to support two new special attributes
"_Filter_ID" and "_Filter_Parameters" so that compression
can be turned on when creating a file using ncgen.
4. Add a detailed description of filtering support
to the user's guide; see the file filters.md
5. Add a test case directory for this: nc_test4/filter_test.
It is fragile and a ./configure flags (-enable-filter-test)
is defined (default disabled) to shut this off this test
to avoid spurious 'make check' failures.
Note that the HDF5 documentation is not up-to-date, so
much of what is encoded here comes from examining the
actual code in the file H5PL.c in the HDF5 source code.
Initial split of Guide from rest of documentation. Using 'tagfiles' to cross-reference from one documentation set to the other works, but then it drags all of the 'external' related pages into the index of the other.
Modified visability of the external groups and pages.
Adding proper section names to 'Example' sections, to avoid Doxygen warnings.

Reorganizing documentation into two separate doxygen projects.
Moved .texi documents into an old directory.
Pulled the tutorial document into a separate document, similar to the guide document.
Turned on treeview
was incomplete; complete the fix.
2. There is an inconsistency in the netcdfh interface
about whether rank (# dimensions) is an int or
size_t. I inadvertently assumed the latter and that
breaks some API calls; so revert back.
