[BOOTDATA][FS] Small adjustments of filesystem drivers registry parameters. - Fix the ErrorControl values to 1 (SERVICE_ERROR_NORMAL). - Fix RamDisk driver type (it's SERVICE_KERNEL_DRIVER, not FS). - btrfs.inf : This is a filesystem driver, so fix its ServiceType. - Move 3rd-party FS data (btrfs, ext2, nfs(d)) from the system hivesys.inf and into their dedicated **.reg.inf files.
Git conversion: Make reactos the root directory, move rosapps, rostests, wallpapers into modules, and delete rossubsys.
