re: https://github.com/Unidata/netcdf-c/pull/2003#issuecomment-847637871
Turns out that mingw defines both _WIN32 and also defines getopt.
This means that this test:
````
#ifdef _WIN32
#include "XGetopt.h"
#endif
````
fails on this error:
````
../include/XGetopt.h:38:24: error: conflicting types for 'getopt'
````
Fix is to replace
````
#ifdef _WIN32
with
#if defined(_WIN32) && !defined(__MINGW32__)
````

* Add a new set of remote tests based on using the thredds-test server.
* Improve error reporting when server requests fail.
* Fix handing of _NCProperties attribute
re: Issue https://github.com/Unidata/netcdf-c/issues/1999
NCclosedir code is incorrect. Fix.
Note that this issue crops up when using a non-VisualStudio windows build
such as Mingw because Mingq defines dirent.h, but Visual Studio does not.
Addendum:
Fix some mingw bugs:
1. Modify XGetopt.h to be conditional on _WIN32 instead of _MSC_VER.
2. Make sure sys/stat.h is included in ncpathmgr.h
re: issue https://github.com/Unidata/netcdf-c/issues/2002
It turns out that ncdump has an error where it assumes that the set of all dimension ids has no holes. That is that (maxid+1) = ndims. This is incorrect for a variety of reasons for netcdf-4.
So instead of counting total number of dimensions in a dataset, it is necessary to look for the maximum dimension id and use that when allocating a table of all dimensions.

Improve the error message and location that is reported when reading a filter with a variable that uses a filter that is not available on the reading platform.
This requires checking the availability of the filter, recording it, and failing when any attempt is made to read or write that variable. A test case was added for this in tst_filter.sh. Also, LOG level 0 message is generated giving the variable and the filter id.
Note that by design if there is no attempt to read or write the variable, then no error is reported; this means that, for example, ncdump -h will list the filter even though it is not actually available. This is important for allowing a user to see the filter details.
