Dennis Heimbigner c68c4c804d Fix undefined references when using Visual Studio 
Fix Issue https://github.com/Unidata/netcdf-c/issues/1725.
Replace PR https://github.com/Unidata/netcdf-c/pull/1726
Also replace PR https://github.com/Unidata/netcdf-c/pull/1694

The general problem is that under Visual Studio, we are seeing
a number of undefined reference and other scoping errors.
The reason is that the code is not properly using Visual Studio
_declspec() declarations.

The basic solution is to ensure that when compiling the code itself
one needs to ensure that _declspec(dllexport) is used. There
are several sets of macros to handle this, but they all rely
on the flag DLL_EXPORT being define when the code is compiled,
but not being defined when the code is used via a .h file.

As a test, I modified XGetOpt.c to build properly. I also
fixed the oc2 library to properly _declspec things like ocdebug.

I also made some misc. changes to get all the tests to run
if cygwin is installed (to get bash, sed, etc).

Misc. Changes:
* Put XGetOpt.c into libsrc and copy at build time
  to the other directories where it is needed.
