Issue:
Filename too long, causing 'make dist' issue on linux.
@DennisHeimbigner 

`make dist` is failing on Ubuntu 21.04 and Ubuntu 20.04 (ARM64).  When running make dist, the following is observed:

```
>netcdf-c-4.8.1.tar.gz
tar: netcdf-c-4.8.1/dap4_test/baselinethredds/GOES16_CONUS_20170821_020218_0.47_1km_33.3N_91.4W.nc4.thredds: file name is too long (max 99); not dumped
tar: Exiting with failure status due to previous errors
```

This causes an error in `make distcheck`.  `dap4_test/test_thredds.sh` fails due to the m issing `.thredds` file.  Is there a replacement we can use, perhaps, with a shorter file name?



Pull request description:
v4.8.1 Wellspring changes to merge back upstream
* Fixes #2077 

This branch will eventually split into the `v4.8.1` release to one side, and a subset of those changes which will go back into the `main` development branch after the `v4.8.1` release.
