PM: rework signal handling
- introduce PROC_STOPPED flag, which tracks whether the process is
stopped on PROC_STOP in the kernel, rather than implicitly deriving
this from PM_SIG_PENDING;
- make the process resumption test based on current state rather than
state transitions;
- add and clarify several flag checks in the signal handling code;
- add test79 to test signal handling robustness.

Input infrastructure, INPUT server, PCKBD driver
This commit separates the low-level keyboard driver from TTY, putting
it in a separate driver (PCKBD). The commit also separates management
of raw input devices from TTY, and puts it in a separate server
(INPUT). All keyboard and mouse input from hardware is sent by drivers
to the INPUT server, which either sends it to a process that has
opened a raw input device, or otherwise forwards it to TTY for
standard processing.
Design by Dirk Vogt. Prototype by Uli Kastlunger.
Additional changes made to the prototype:
- the event communication is now based on USB HID codes; all input
drivers have to use USB codes to describe events;
- all TTY keymaps have been converted to USB format, with the effect
that a single keymap covers all keys; there is no (static) escaped
keymap anymore;
- further keymap tweaks now allow remapping of literally all keys;
- input device renumbering and protocol rewrite;
- INPUT server rewrite, with added support for cancel and select;
- PCKBD reimplementation, including PC/AT-to-USB translation;
- support for manipulating keyboard LEDs has been added;
- keyboard and mouse multiplexer devices have been added to INPUT,
primarily so that an X server need only open two devices;
- a new "libinputdriver" library abstracts away protocol details from
input drivers, and should be used by all future input drivers;
- both INPUT and PCKBD can be restarted;
- TTY is now scheduled by KERNEL, so that it won't be punished for
running a lot; without this, simply running "yes" on the console
kills the system;
- the KIOCBELL IOCTL has been moved to /dev/console;
- support for the SCANCODES termios setting has been removed;
- obsolete keymap compression has been removed;
- the obsolete Olivetti M24 keymap has been removed.

Import NetBSD vndconfig(8)
The tool has been changed heavily to match our VND driver model.
NetBSD is in the process of renaming it from vnconfig(8) to
vndconfig(8). To keep things in sync, we have to play along.

TTY: use libchardriver; clean up
- writing to a PTY master side blocks if there is not already a
blocked reader on the slave side, and select now reflects this;
- internally, TTY now uses a test based on "caller != NONE" rather
than "grant != GRANT_INVALID" to identify whether a call is
currently ongoing;
- "offset" fields have been removed as they equal the corresponding
"cum" fields;
- improved variable typing and function naming here and there;
- various other small fixes.
