Make sys/buf.h, sys/pipe.h, sys/fs/devfs/devfs*.h headers usable in userspace, assuming that the consumer has an idea what it is for. Unhide more material from sys/mount.h and sys/ufs/ufs/inode.h, sys/ufs/ufs/ufsmount.h for consumption of userspace tools, with the same caveat. Remove unacceptable hack from usr.sbin/makefs which relied on sys/buf.h being unusable in userspace, where it override struct buf with its own definition. Instead, provide struct m_buf and struct m_vnode and adapt code to use local variants.
