Dennis Heimbigner f0f0f39950 Cleanup various Zarr-related build issues
# Description
Remove various obsolete build options. Also do some code movement.

## Specific Changes

* The remotetest server is sometimes unstable, so provide a mechanism
  to force disabling calls to remotetest.unidata.ucar.edu.
  This is enabled by adding a repository variable named
  REMOTETESTDOWN with the value "yes".
* Fix CMakeLists.txt to use the uname command as an alternate
  to using the hostname command (which does not work under cygwin).
* Remove the JNA stuff as obsolete
* Remove the ENABLE_CLIENTSIDE_FILTERS options since it has been
  disabled for a while.
* Fix bad option flag in some github action .yml files: change --disable-xml2 to --disable-libxml2
* Collect globalstate definitions into nc4internal.h
* Remove ENABLE_NCZARR_FILTERS_TESTING option as obsolete and replace
  with ENABLE_NCZARR_FILTERS
* Move some dispatcher independent functions from libsrc4/nc4internal.c to libdispatch/ddispatch.c
* As a long term goal, and because it is now the case that --enable-nczarr
    => USE_NETCDF4, make the external options --enable-netcdf-4 and
    --enable-netcdf4 obsolete in favor of --enable-hdf5
    We will do the following for one more release cycle.
        1. Make --enable-netcdf-4 be an alias for --enable-netcdf4.
        2. Make --enable-netcdf4 an alias for --enable-hdf5.
        3. Internally, convert most uses of USE_NETCDF_4 ad USE_NETCDF4 to USE_HDF5
    After the next release, --enable-netcdf-4 and --enable-netcdf4 will
    be removed.

# Define a function that attempts to locate a
# plugin with a given canonical name.
# Assumptions:
# 1. plugins is a top-level directory, possibly in "build"
# Inputs:
# $1 is the canonical name
# $2 is 1 if we are running under cmake
# $3 is 1 if we are running using Visual Studio, blank otherwise
# $4 is the build type; only used if $3 is 1
# Outputs:
# return code is 0 is success, 1 if failed
# Variable HDF5_PLUGIN_LIB is set to the library file name
# Variable HDF5_PLUGIN_DIR is set to the absolute path to the
# directory containing the plugin library file
# Local variables are prefixed with FP_
#
# Note: we assume that the use of the CMAKE_BUILD_TYPE
# is obviated by setting the LIBRARY_OUTPUT_DIRECTORY
# variables: see hdf5plugins/CMakeLists.txt
# Define location of execution
