Dennis Heimbigner 9380790ea8 Support MSYS2/Mingw platform
re:

The current netcdf-c release has some problems with the mingw platform
on windows. Mostly they are path issues.

Changes to support mingw+msys2:
-------------------------------
* Enable option of looking into the windows registry to find
  the mingw root path. In aid of proper path handling.
* Add mingw+msys as a specific platform in configure.ac and move testing
  of the platform to the front so it is available early.
* Handle mingw X libncpoco (dynamic loader) properly even though
  mingw does not yet support it.
* Handle mingw X plugins properly even though mingw does not yet support it.
* Alias pwd='pwd -W' to better handle paths in shell scripts.
* Plus a number of other minor compile irritations.
* Disallow the use of multiple nc_open's on the same file for windows
  (and mingw) because windows does not seem to handle these properly.
  Not sure why we did not catch this earlier.
* Add mountpoint info to dpathmgr.c to help support mingw.
* Cleanup dpathmgr conversions.

Known problems:
---------------
* I have not been able to get shared libraries to work, so
  plugins/filters must be disabled.
* There is some kind of problem with libcurl that I have not solved,
  so all uses of libcurl (currently DAP+Byterange) must be disabled.

Misc. other fixes:
------------------
* Cleanup the relationship between ENABLE_PLUGINS and various other flags
  in CMakeLists.txt and configure.ac.
* Re-arrange the TESTDIRS order in Makefile.am.
* Add pseudo-breakpoint to nclog.[ch] for debugging.
* Improve the documentation of the path manager code in ncpathmgr.h
* Add better support for relative paths in dpathmgr.c
* Default the mode args to NCfopen to include "b" (binary) for windows.
* Add optional debugging output in various places.
* Make sure that everything builds with plugins disabled.
* Fix numerous (s)printf inconsistencies betweenb the format spec
  and the arguments.
