- Sync RPCRT4.dll to Wine-20070507 (recent release Wine 0.9.36).
- Fix a couple of headers.
- NOTE: I tested this rpcrt4 under ReactOS 0.3.1 and it boots normally. However, for future work, a wrapper library around winsock should be built, and a rpcrt4_ros.diff should be developer. Right now it's manually synced, and contains a few modifications (marked as #ifdef FIX_LATER in most cases).
Also, I'm not going to do a proper vendor import of this library, because next sync will most probably be autosync.
In case of problems, it could be reverted.
