DWesl 0eed60a295 BLD: Get netCDF4 build working on Windows.
Most changes are to get plugins working.
libdispatchdreg.c went in in unidata/netcdf-c#2460,
after I'd done it here.

Summary of individual changes below.

BLD: Remove declspec(dllexport); in dreg.c.

By removing the explicit handling, the automatic handling
(equivalent to --export-all-symbols with recent GNU tools)
will be enabled again, so the generated library will have
more than one function exported.

BLD: Link plugins against libnetcdf on Cygwin.

BLD: Add AM_LDFLAGS to plugin _LDFLAGS to pass -no-undefined.

BLD: Link ncz*filters plugins against libnetcdf.

BLD: Add AM_LDFLAGS to test plugin _LDFLAGS.

Also move rpath from AM_LDFLAGS to test plugin _LDFLAGS.

TST: Don't run nczarr_test/run_specific_filters.sh on Cygwin.

It takes over half an hour to complete, where the others take a minute or less.

TST: Try to find the hanging Cygwin test.
