RFR 8200468: Port the native GSS-API bridge to Windows

[Weijun Wang]

Hi Valerie

I updated the webrev at

  http://cr.openjdk.java.net/~weijun/8200468/webrev.01/

The only change is that I prepend "GSS_DLLIMP" to all gss_* functions in gssapi.h. The file has the following lines

 283 #if defined (_WIN32) && defined (_MSC_VER)
 284 # ifdef GSS_DLL_FILE
 285 #  define GSS_DLLIMP __declspec(dllexport)
 286 # else
 287 #  define GSS_DLLIMP __declspec(dllimport)
 288 # endif
 289 #else
 290 # define GSS_DLLIMP
 291 #endif

I added it so the exact same header file can be used to write a native GSS-API library which would export these functions.

Is this OK? Tests run fine with both MIT krb5 and Heimdal libraries.

Thanks
Max
