re: PR https://github.com/Unidata/netcdf-c/pull/2655
This PR modifies the transient types PR so that all created
transient types are given a created unique name (within a
group). The form of the name is "_Anonymous<Class>NN". The class
is the user-defined type class: Enum, Compound, Opaque, or
Vlen. NN is an integer identifier to ensure uniqueness.
Additionally, this was applied to DAP/4 anonymous dimensions.
This also required some test baseline data changes.
The transient test case is modified to verify that the name exists.

After some discussion, the issue of applying filters on variables
whose type is not fixed size, was resolved as follows:
1. A call to nc_def_var_filter will ignore such filters, but will issue a log warning.
2. Loading (from an existing file) a variable whose type is not fixed-size and which has filters, will cause the variable to be suppressed.
This PR enforces those rules.
### Misc. Other changes
* Add a test case to test the vlen change.
* Make some minor clean-ups in various cmake and automake files.
* Remove unused test
The `FIND_PACKAGE` should not be called if the filter/compression library is not enabled. It was causing some inconsistencied in link libraries and CMake configure output...

Apparently (see above PR) tinyxml2 now works under OS/X.
So this PR is a follow on to the above PR. It modifies
our OS/X github action to test tinyxml2 under OS/X.
re: Issue https://github.com/Unidata/netcdf-c/issues/2704
The issue reported problems accessing e.g. opendap.earthdata.nasa.gov,
which uses the authentication mechanisms of urs.earthdata.nasa.gov.
The file *docs/auth.md* describes how to setup the proper authorization
mechanisms for earthdata, but there turned out to be some bugs
in the code that prevented this from working.
## Primary Changes
* Add some clarification text to *auth.md*.
* Fix the process for loading and merging *.ncrc* and *.dodsrc* file to conform to documentation.
* Fix *NC_s3urlrebuild* so that non-S3 urls are passed through unchanged.
* Fix a bug in the .rc test *test_rcmerge.sh*.
Add the option "--disable-network-access" (automake)
or "-DENABLE_NETWORK_ACCESS=OFF" (cmake).
When disabled, this option transitively disables all
network access capabilities and testing.
If set, this option implies the following:
* --disable-dap
* --disable-byterange
* --disable-s3
This PR answers a request for a feature from Ed Hartnett.
## Misc. Other changes
* Take the opportunity to clean up some old, unused options;
e.g. --enable-multifilters.
* Fix bug in using S3 urls.
