e54815ad40 si_cmdname() is defined only when SI_DEBUG is enabled, thus
using this function in simple printf() causes compile-time
problems. Use conditionally enabled DPRINT() macro instead.

434cb98901 Pass 1 of mpsafetty-ifying si(4). It compiles and has basic functionality,
but needs a lot more work.  In particular, it has no flow control and has
a tendency to race when giving commands.  It still uses Giant for the
tty and driver lock, but this is a keep-it-simple feature for now.
Some of the [temporary] proliferation of messages lines are way too long.

2ae1fdab5a Remove sicontrol(8)'s "ttystat".
In the FreeBSD base system, there are only two utilities that use struct
tty, namely pstat and sicontrol. The sicontrol utility calls the
TCSI_TTY ioctl(), which copies struct tty back to userspace.

sicontrol should not have this functionality. The same data is already
provided by pstat. If we really want to be able to export these numbers
through a file descriptor to userspace, we can export struct xtty, which
should provide a better abstraction. The ttystat option was only used as
a debugging aid.

This makes sicontrol compile in the mpsafetty branch.

420a38dd4b Wrap the EISA-specific parts of the dpt(4) and si(4) back-ends in
the newly added DEV_EISA. This is done so that these back-ends can
be compiled on platforms not providing in{b,w,l}()/out{b,w,l}() and
friends (but may wish to use them together with bus front-ends other
than the EISA one).

cb9ea5f4cb Pick the hotchar out of the tty structure instead of caching private
copies.

No current line disciplines have a dynamically changing hotchar, and
expecting to receive anything sensible during a change in ldisc is
insane so no locking of the hotchar field is necessary.

44731cab3b Change the suser() API to take advantage of td_ucred as well as do a
general cleanup of the API.  The entire API now consists of two functions
similar to the pre-KSE API.  The suser() function takes a thread pointer
as its only argument.  The td_ucred member of this thread must be valid
so the only valid thread pointers are curthread and a few kernel threads
such as thread0.  The suser_cred() function takes a pointer to a struct
ucred as its first argument and an integer flag as its second argument.
The flag is currently only used for the PRISON_ROOT flag.

This is functionally equivalent to teh previousl -current except

931e989797 Always leave SP_DCEN on (monitor DCD). Otherwise the firmware *really*
does ignore DCD.  Even TIOCMGET cannot read DCD as the firmware doesn't
report it.  This has pretty interesting effects for ppp(8) which runs
in clocal mode and polls carrier (!).  (Specialix's linux driver does
this too)

Also update the firmware to 3.0.6 for the SX cards, as apparently there
was a problem with floating (disconnected) DCD pins causing stray carrier
transitions, especially at port open time.

It seems to work here, and carrier loss is detected nearly immediately
rather than having to wait for a LQR timeout (a few minutes) before ppp(8)
gives up.
