With cons25, there are printable characters below 0x1B. This is not the
case with ASCII, UTF-8, etc. but in this case we just have to.
Also don't set LC_CTYPE to UTF-8 when libteken is compiled without UTF-8
in the demo-application.

It turns out I was looking too much at mimicing xterm, that I didn't
take the differences of cons25 into account. There are some differences
between xterm and cons25 that are important. Create a new #define called
TEKEN_CONS25 that can be toggled to switch between cons25 and xterm
mode.
- Don't forget to redraw the cursor after processing a forward/backward
tabulation.
- Implement cons25-style (WYSE?) autowrapping. This form of autowrapping
isn't that nice. It wraps the cursor when printing something on column
80. xterm wraps when printing the first character that doesn't fit.
- In cons25, a \t shouldn't overwrite previous contents, while xterm
does.

to ip_output(). The destionation is represented in a sockaddr{} object
that may contain other pieces of information, e.g., port number. This
same destination sockaddr{} object may be passed into L2 code, which
could be used to create a L2 entry. Since there exists a L2 table per
address family, the L2 lookup function can make address family specific
comparison instead of the generic bcmp() operation over the entire
sockaddr{} structure.
Note in the IPv6 case the sin6_scope_id is not compared because the
address is currently stored in the embedded form inside the kernel.
The in6_lltable_lookup() has to account for the scope-id if this
storage format were to change in the future.
During startup some of the syscons TTY's are used to set attributes like

Fix the issue by leaving the TTY opened when it is used as the console

completely valid to place the cursor outside the scrolling region.

whole KVA space using one locked 4MB dTLB entry per GB of physical
memory. On Cheetah-class machines only the dt16 can hold locked
entries though, which would be completely consumed for the kernel
TSB on machines with >= 16GB. Therefore limit the KVA space to use
no more than half of the lockable dTLB slots, given that we need
them also for other things.
- Add sanity checks which ensure that we don't exhaust the (lockable)

Some time ago I started working on a library called libteken, which is
terminal emulator. It does not buffer any screen contents, but only
keeps terminal state, such as cursor position, attributes, etc. It
should implement all escape sequences that are implemented by the
cons25 terminal emulator, but also a fair amount of sequences that are
present in VT100 and xterm.
A lot of random notes, which could be of interest to users/developers:
- Even though I'm leaving the terminal type set to `cons25', users can
do experiments with placing `xterm-color' in /etc/ttys. Because we
only implement a subset of features of xterm, this may cause
artifacts. We should consider extending libteken, because in my
opinion xterm is the way to go. Some missing features:
- Keypad application mode (DECKPAM)
- Character sets (SCS)
- libteken is filled with a fair amount of assertions, but unfortunately
we cannot go into the debugger anymore if we fail them. I've done
development of this library almost entirely in userspace. In
sys/dev/syscons/teken there are two applications that can be helpful
when debugging the code:
- teken_demo: a terminal emulator that can be started from a regular
xterm that emulates a terminal using libteken. This application can
be very useful to debug any rendering issues.
- teken_stress: a stress testing application that emulates random
terminal output. libteken has literally survived multiple terabytes
of random input.
- libteken also includes support for UTF-8, but unfortunately our input
layer and font renderer don't support this. If users want to
experiment with UTF-8 support, they can enable `TEKEN_UTF8' in
teken.h. If you recompile your kernel or the teken_demo application,
you can hold some nice experiments.
- I've left PC98 the way it is right now. The PC98 platform has a custom
syscons renderer, which supports some form of localised input. Maybe
we should port PC98 to libteken by the time syscons supports UTF-8?
- I've removed the `dumb' terminal emulator. It has been broken for
years. It hasn't survived the `struct proc' -> `struct thread'
conversion.
- To prevent confusion among people that want to hack on libteken:
unlike syscons, the state machines that parse the escape sequences are
machine generated. This means that if you want to add new escape
sequences, you have to add an entry to the `sequences' file. This will
cause new entries to be added to `teken_state.h'.
- Any rendering artifacts that didn't occur prior to this commit are by
accident. They should be reported to me, so I can fix them.

2. Add IGNORE_FILES to the example rc [2] (and remove IGNORE_MOTD)
3. Update the EXIT STATUS section for [3] and [4]

1. Various improvements to the mtree (-U) feature:
a. Seperate the notion of directory and file (user can override db path)
b. Only check for the existence of the mtree file if -U is set
c. Use mktemp to create the new version of the file
d. More safely install the new file
e. Standardize error messages a bit
2. Remove the last of the MAKEDEV stuff (RIP)
New Features
============
1. Switch to using the top level (e.g., /usr/src) Makefile, and specify
that we should use the *.mk files from the source directory instead of
the installed versions. [1][2] This allows easier cross builds and
simplifies (or in some cases permits) upgrading.
2. Check for the deprecated 'nodev' option in /etc/fstab [3]
3. Add support for the IGNORE_FILES variable [4] and deprecate IGNORE_MOTD
accordingly.
4. Before installing a file check to make sure that the target does not
already exist as a directory [5]
5. Check to be sure that the file installed and error out if not

1. It was added without my consent, review, or even a heads up
2. It is something that I've repeatedly said I do not want, and certainly
do not want as the default
3. It is poorly implemented (much too complex, produces false positives
e.g., /etc/mail/helpfile)
Given that this is a situation that comes up very infrequently (usually
only for a major version upgrade) and can usually be handled simply
enough on a one-off basis, I will once again point out that I think
this is a Bad Idea. I would be willing to consider a better implementation
as an option that is off by default.

When sysctl() is being called with a buffer that is too small, it will
