5ae60510dc Add a compile-time check for IPC messages size
This patch adds compile-time check for each message type to ensure the
size is within the IPC assumptions.

This will allow messages specific to a protocol to use from now on the
proper types for each fields, while preventing from any unsuspected
side effect when updating type definitions.

9a2e578a5c Remove sys/stdlib.h
This file was copied over to allow for the compilation of some
of the arch/i386 code, due to a bug in lib/libc/compat/Makefile.inc.

This patch fixes the situation, and removes the now useless header, as
well as remove a patch in lib/libc/stdlib/putenv.c

87c599da2d PM/VFS protocol: prefix with VFS_PM_
These calls are sent to VFS, and thus should be prefixed with VFS_.
Clean up the protocol and PM's main function a bit.

Since the protocol is substantially big and different from normal VFS
requests, this protocol retains its own numbering range for now.

44d3230e40 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.

80bd109cd3 libsys: various updates
- move system calls for use by services from libminlib into libsys;
- move srv_fork(2) and srv_kill(2) from RS and into libsys;
- replace getprocnr(2) with sef_self(3);
- rename previous getnprocnr(2) to getprocnr(2);
- clean up getepinfo(2);
- change all libsys calls that used _syscall to use _taskcall, so as
  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.

f310aefcbd PM: resolve fork/kill race condition
When a process forks, VFS is informed on behalf of the child. This is
correct, because otherwise signals to the new child could get lost.
However, that means that the parent is not blocked from being killed
by a signal while the child is blocked on this VFS call. As a result,
by the time that the VFS reply comes in, the parent may already be
dead, and the child may thus have been assigned a new parent: INIT.

Previously, PM would blindly reply to the parent when the VFS reply
for the fork came in. Thus, it could end up sending a reply to INIT,
even though INIT did not issue the fork(2) call. This could end up
satisfying a different call from INIT (typically waitpid(2)) and then
cause an error when that other call was complete.

It would be possible to set VFS_CALL on both forking parent and child.
This patch instead adds a flag (NEW_PARENT) to note that a process's
parent has changed during a VFS call.

664b726cd3 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.

e5cc85fdc4 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.

9e3e032c26 UDS: sendmsg/recvmsg fixes
- sendmsg: the accumulation of multiple in-flight file descriptors was
  already described in the comments; now the code actually does what
  the comments say :) -- also, added robustness in case of a failure;
- recvmsg: only create a socket rights message if there are file
  descriptors pending at all;
- recvmsg: copy back the control message length;
- recvmsg: use CMSG_SPACE instead of CMSG_LEN to compute sizes.

Not sure if all of this is now working according to specification,
but at least tmux seems to be happy with it.

6d466f941b 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.

As the situation is right now, importing one of the commands the

instead of one file being symlinked multiple times.

6b3f4dc157 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.
