This allows us to write things like this:
message m;
m.m_notify.interrupts = new_value;
or
message *mp;
mp->m_notify.interrupts = new_value;
The shorthands macro have been adapted for the new scheme, and will be
kept as long as we have generic messages being used.

. create signals-related struct message type to store sigset_t
directly
. create notify-specific message types, so the generic NOTIFY_ARG
doesn't exist anymore
. various related test expansions, improvements, fixes
. add a few error-checks to sigismember() calls
. rename kernel call specific signals fields to SYS_*

* Also change _orig to _intr for clarity
* Cleaned up {IPC,KER}VEC
* Renamed _minix_kernel_info_struct to get_minix_kerninfo
* Merged _senda.S into _ipc.S
* Moved into separate files get_minix_kerninfo and _do_kernel_call
* Adapted do_kernel_call to follow same _ convention as ipc functions
* Drop patches in libc/net/send.c and libc/include/namespace.h

- 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.

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.
