to the screen on which they are being called. The driver cannot guess
this by itself but it is needed to implement, at least, the getwschar and
putwschar functions in the correct place. There are no functional changes
yet.
Tested on i386 (vga, vga_raster, machfb, vesafb), macppc and sparc64.

N.B. stf is a cloning device, so it still must be enabled by
"ifconfig stf0 create".
- use vmspace rather than proc or lwp where appropriate.
the latter is more natural to specify an address space.
(and less likely to be abused for random purposes.)
- fix a swdmover race.
- Replace references to linesw[0] with a ttyldisc_default() function
that returns the default ("termios") line discipline.
- The linesw[] array is gone, replaced by a linked list.
- ttyldisc_add() and ttyldisc_remove() have been replaced by
ttyldisc_attach() and ttyldisc_detach().
- Things that provide line disciplines are now responsible for
registering those disciplines with the system. The linesw
structures are no longer declared in tty_conf.c
- Line disciplines are now refcounted; a lookup causes a reference to
be held. ttyldisc_release() releases the reference. Attempts to
detach an in-use line discipline result in EBUSY.
- Fix function signature lossage in if_sl.c, if_strip.c, and tty_tb.c
that was masked by the old tty_conf.c
- tty_init() is no longer necessary; delete it and its call from main().
was developed as part of Google's Summer of Code 2005 program. This
change adds the kernel code, the mount_tmpfs utility, a regression test
suite and does all other related changes to integrate these.
The file-system is still *experimental*. Therefore, it is disabled by
default in all kernels. However, as typically done, a commented-out
entry is added in them to ease its setup.
Note that I haven't commited the required mountd(8) changes to be able
to export tmpfs file-systems because NFS support is still very unstable
and because, before enabling it, I'd like to do some other changes.
OK'ed by my project mentor, William Studenmund (wrstuden@).
use from checking the proc's uid to suser(9), and account for the use of
privileges. Noted by David Holland in PR kern/31126.
Also change this to use the proc argument instead of curproc.

the length in now known to all relevant parties, so this avoids
duplication of information, and we can allocate that thing in
drivers without hacks
