Log:
- Fixed up KdComPortInUse so that we don't crash when using TinyKRNL/Windows kdcom.dll
anymore (due to serial.sys). WinDBG should work a lot better now.
- Implemented hack so that NT-style sprintf can work.
- Implement MiCacheImageSymbols and upgrade MmLoadSystemImage to load symbols for
drivers/images which have a debug section.
- Implemented a case in MiResolveImageReferences which was getting hit.
- Don't leak a section object reference each time we load a driver.
- Set the LoadedImports pointer in the loader entry, and set the proper flags after
loading a driver.
- Do image notifications after loading a driver, if they're enabled.
