Use static inline for cd1400_write_ccr() because clang 16 has issues with it.

Also remove some unused prototypes.

Remove unused device poll functions.

Also remove unneeded includes of <sys/poll.h> and <sys/select.h>.

Some addenda from jsg@.

OK miod@ mpi@

Constify struct cfattach.

Use ttopen in tty drivers open functions as ttysleep string, as the others do.

Implement kqfilter matching the corresponding poll routine.

magma(4): timeout_add(9) -> timeout_add_msec(9)

Remove the tick conversion stuff and use timeout_add_msec(9) directly.

Compile-tested by kn@.

Convert infinite sleeps to {m,t}sleep_nsec(9).

ttysleep(): drop unused timeout parameter

All callers sleep indefinitely.

Remove almost unused `flags' argument of suser().

The account flag `ASU' will no longer be set but that makes suser()
mpsafe since it no longer mess with a per-process field.

No objection from mill

First step towards making uiomove() take a size_t size argument:
- rename uiomove() to uiomovei() and update all its users.
- introduce uiomove(), which is similar to uiomovei() but with a size_t.

Allow tty drivers to request larger buffers at attach time using a
max-baud-rate hint. Adjust TTYHOG (the nearly full logic) to this new
situation. The larger buffers are required by the very high speed
KDDI devices in Japan (CF com, or USB ucom) so those are the only two
drivers which currently ask for a larger buffer size.

Every selwakeup() should have a matching KNOTE() (even if kqueue isn't
supported it doesn't do any harm), so put the KNOTE() in selwakeup() itself and
remove it from any occurences where both are used, except one for kqueue itself
and one in sys_pipe.c (where the selwakeup is under a PIPE_SEL flag).

Based on a diff from tedu.

Merge tty_attach() in ttymalloc() and tty_detach() in ttyfree(). The need for
separate tty registering is gone now that sparc has switched to wscons, and
this makes the code less error-prone.

Also, remove tests for ttymalloc() failure, since it uses M_WAITOK.
