- Implement NP (ASCII 12, Form Feed). When used with cons25, it should
clear the screen and place the cursor at the top of the screen. When
used with xterm, it should just simulate a newline.
- When we want to use xterm emulation, make teken_demo set TERM to
xterm.

functions used in the bootloader. The goal is to make the code more
readable and smaller (especially because we have size issues
in the loader's environment).
High level description of the changes:
+ define some string manipulation functions to improve readability;
+ create functions to manipulate module descriptors, removing some
duplicated code;
+ rename the error codes to ESOMETHING;
+ consistently use set_environment_variable (which evaluates
$variables) when interpreting variable=value assignments;
I have tested the code, but there might be code paths that I have
not traversed so please let me know of any issues.
Details of this change:
--- loader.4th ---
+ add some module operators, to remove duplicated code while parsing
module-related commands:
set-module-flag
enable-module
disable-module
toggle-module
show-module
--- pnp.4th ---
+ move here the definition related to the pnp devices list, e.g.
STAILQ_* , pnpident, pnpinfo
--- support.4th ---
+ rename error codes to capital e.g. ENOMEM EFREE ... and do obvious
changes related to the renaming;
+ remove unused structures (those relevant to pnp are moved to pnp.4th)
+ various string functions
- strlen removed (it is an internal function)
- strchr, defined as the C function
- strtype -- type a string to output
- strref -- assign a reference to the string on the stack
- unquote -- remove quotes from a string
+ remove reset_line_buffer
+ move up the 'set_environment_variable' function (which now
uses the interpreter, so $variables are evaluated).
Use the function in various places
+ add a 'test_file function' for debugging purposes

Because we now have cons25-style linewrapping, we must also use cons25-
style reverse linewrapping. This means that a ^H on column 0 will move
the cursor one line up.
Also fix a small regression: if the user invokes a RIS (Reset to Initial
State), we must show the cursor again.

During boot, the domain list is locked with Giant. It is not possible to
register any protocols after the system has booted, so the lock is only
used to protect insertion of entries.
There is already a mutex in uipc_domain.c called dom_mtx. Use this mutex
to lock the list, instead of using Giant. It won't matter anything with
respect to performance, but we'll never get rid of Giant if we don't
remove from places where we don't need it.

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

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.

whole KVA space using one locked 4MB dTLB entry per GB of physical

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)
TLB slots.

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.
