vanjeff e5f461a850 1. Remove #ifdef _MSC_EXTENSION_ from all source files 
2. Remove #ifdef _GCC_ from all resource files
3. Remove #if 0 from all resource files
4. Remove #ifdef MDE_CPU_IPF and #ifdef MDE_CPU_EBC
5. Remove #progam from Decode.c
6. Remove #ifdef TIANO_EXTENSION_FLAG from source files
7. Remove #ifdef SUPPORT_IPV6, since code base doesn't support IPV6 at all.
8. Remove #ifdef SpecialNowaitVersion from pxe_bc_mtftp.c, since it's only used for test.
