The plugin interfaces were originally implemented for use on Unix where KRB5_CALLCONV, HEIM_CALLCONV and similar are defined as nothing. However, on 32-bit Windows the calling convention matters and executing a __stdcall function through a __cdecl function pointer will result in failures. This change updates the krb5plugin_windc, krb5plugin_service_locate, krb5plugin_send_to_kdc plugins to specify the KRB5_CALLCONV for functions. This brings the plugins into compliance with the heim_plugin_common interface requirement that init() and fini() use the platform specified HEIM_CALLCONV. The krb5-plugin(7) man page is updated and the lib/krb5/test_plugin test is also fixed. With this change all tests pass on 32-bit Windows. Change-Id: Ic9d2e1285c9c179e3898dc9d071ed092bcddc406
