1. When model is detected as NC_FORMATX_NC3 and is called from
nc_create_par, change the model to NC_FORMATX_PNETCDF.
2. When called from nc_create() or nc_open(), using NC_MPIIO or
NC_MPIPOSIX is considered invalid.
3. Handle the case when NETCDF4 is not enabled but cmode/omode
contains NC_NETCDF4.
4. Handle the case when PNETCDF is not enabled but cmode/omode
contains NC_PNETCDF.
5. Correct comments about PnetCDF only handles CDF-5 files.
6. Add a check for MPI_ERR_NO_SUCH_FILE error class.
Make NC_check_file_type() static, as it is used in dfile.c only.
using NC_MPIIO or NC_MPIPOSIX explicitly is not necessary.
These 2 subroutines call NC_create() and NC_open() with argument
useparallel set to 1, which should be used to tell which I/O
driver to use underneath.
re: https://github.com/Unidata/netcdf-c/issues/972
The current szip plugin code in the HDF5 library has some
unexpected behaviors that require some changes to how
nc_inq_var_szip is implemented and to the corresponding tests:
nc_test4/{test_szip,tst_vars3}.
Specifically, the following can happen:
1. The number of parameters provided by the user will be two,
but the number of parameters returned by nc_inq_var_filter
will be four because the HDF5 code (H5Zszip) will add two
extra parameters for internal use. It turns out that the two
parameters provided when calling nc_def_var_filter correspond
to the first two parameters of the four parameters returned
by nc_inq_var_filter.
2. The nc_inq_var_szip values corresponding to the ones provided
by the caller may be different than those provided by
nc_def_var_filter. The value of the options_mask argument is
known to add additional flag bits, and the pixels_per_block
parameter may be modified.

One of the less common use cases for the in-memory feature is
apparently failing with HDF5-1.10.x. The fix is complicated and
requires significant changes to libhdf5/nc4memcb.c. The current
setup is detailed in the file docs/inmeminternal.dox.
Additionally, it was discovered that the program
nc_test/tst_inmemory.c, which is invoked by
nc_test/run_inmemory.sh, actually was failing because of the
above problem. But the failure is not detected since the script
does not return non-zero value.
Other Changes:
1. Fix nc_test_tst_inmemory to return errors correctly.
2. Make ncdap_tests/findtestserver.c and dap4_tests/findtestserver4.c
be generated from ncdap_test/findtestserver.c.in.
3. Make LOG() print output to stderr instead of stdout to
avoid contaminating e.g. ncdump output.
4. Modify the handling of NC_INMEMORY and NC_DISKLESS flags
to properly handle that NC_DISKLESS => NC_INMEMORY. This
affects a number of code pieces, especially memio.c.
The identifier typename is apparently a reserved word in C++.
It is used as a fieldname in the ALignment struct in
include/ncoffsets.h.
Change the field name to type_name in ncoffsets.h
and also in libdispatch/doffsets.c, which uses that field.
