For common calls, give servers unique call numbers

The getsysinfo(2), getrusage(2), and svrctl(2) calls used the same
call number to different services. Since we want to give each service
its own call number ranges, this is no longer tenable. This patch
introduces per-service call numbers for these calls.

Note that the remainder of the COMMON_ range is left intact, as these
the remaining requests in it are processed by SEF and thus server-
agnostic. The range should really be prefixed with SEF_ now.

to avoid going through errno to pass errors; this is already how
most calls work anyway, and many of the calls previously using
_syscall were already assumed to return the actual error;
- initialize request messages to zero, for future compatibility
(note that this does not include PCI calls, which are in need of a
much bigger overhaul, nor kernel calls);
- clean up more of dead DS code as a side effect.

VFS: further cleanup of device code

- all TTY-related exceptions have now been merged into the regular
code paths, allowing non-TTY drivers to expose TTY-like devices;
- as part of this, CTTY_MAJOR is now fully managed by VFS instead of
being an ugly stepchild of the TTY driver;
- device styles have become completely obsolete, support for them has
been removed throughout the system; same for device flags, which had
already become useless a while ago;
- device map open/close and I/O function pointers have lost their use,
thus finally making the VFS device code actually readable;
- the device-unrelated pm_setsid has been moved to misc.c;
- some other small cleanup-related changes.

Extend dupfrom(2) into copyfd(2)

This single function allows copying file descriptors from and to
processes, and closing a previously copied remote file descriptor.
This function replaces the five FD-related UDS backcalls. While it
limits the total number of in-flight file descriptors to OPEN_MAX,
this change greatly improves crash recovery support of UDS, since all
in-flight file descriptors will be closed instead of keeping them
open indefinitely (causing VFS to crash on system shutdown). With the
new copyfd call, UDS becomes simpler, and the concept of filps is no
longer exposed outside of VFS.

This patch also moves the checkperms(2) stub into libminlib, thus
fully abstracting away message details of VFS communication from UDS.

at_wini: PCI-only now; one controller per instance

- remove non-PCI support, since all supported platforms with at_wini
devices also have PCI support by now;
- correspondingly, stop using information from the BIOS altogether;
- limit each driver instance to one controller, to be in line with
the general MINIX3 one-instance-per-controller driver model; this
limits the number of disks per at_wini instance to four;
- go through the controllers by the order of their occurrence in the
PCI table, thus removing the exception for compatibility devices;
- let the second at_wini instance shut down silently if there is only
one IDE controller;
- clean up some extra code we don't need anymore, and resolve some
WARNS=5 level warnings.

Overall, these changes should simplify automatic loading of the right
disk drivers at boot time in the future.

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.

VM: readd support for forgetting cached FS blocks

Not all services involved in block I/O go through VM to access the
blocks they need. As a result, the blocks in VM may become stale,
possibly causing corruption when the stale copy is restored by a
service that does go through VM later on. This patch restores support
for forgetting cached blocks that belong to a particular device, and
makes the relevant file systems use this functionality 1) when
requested by VFS through REQ_FLUSH, and 2) upon unmount.
