- all TTY-related exceptions have now been merged into the regular code paths, allowing non-TTY drivers to expose TTY-like devices; - as part of this, CTTY_MAJOR is now fully managed by VFS instead of being an ugly stepchild of the TTY driver; - device styles have become completely obsolete, support for them has been removed throughout the system; same for device flags, which had already become useless a while ago; - device map open/close and I/O function pointers have lost their use, thus finally making the VFS device code actually readable; - the device-unrelated pm_setsid has been moved to misc.c; - some other small cleanup-related changes.
