baseaddress.cfg - Add entry for midimap.dll. Fix msacm's base address. It was conflicting with iplhapi and generated an unncessary relocation and error message.

Makefile - Add entry for midimap.dll, Build mmdrv because it's trying to get loaded at system startup and that caused an error
bootdata/hivedef.inf - Create PaintDesktopVersion key and set it to 0. Win32k was trying to read this value and gave an error message because it did not exist.
lib/samlib/samlib.c - Silence samlib for informational messages that aren't errors.(if NDEBUG is on)
lib/userenv/directory.c -Silence for informational messages that aren't errors (if NDEBUG is on)
lib/setupapi/devinst.c - Turn SetupDiInstallClassW blank debug message into something a little more informational.
lib/syssetup/install.c - Make syssetup check if samlib returned ERROR_USER_EXISTS, in which case instead of pointlessly rebooting (which probably never allowed the user to actually setup ros...if error_user_Exists is returned it means  that setup was abandonned for some reason, so we would want to restart it instead of giving up), it will  restart setup.
