cc59831179 keymaps: improve keypad slash support
Now that the keymaps can distinguish between the regular slash key
and the slash key on the numeric keypad, we can avoid localization
of the latter.

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.

ec2359d566 TTY: allow selecting on translated minors
Due to the existence of /dev/console and /dev/log, and the new
"console=" setting, it is now possible that a single non-PTY object
(e.g. serial) is accessible through two different minor numbers.  This
poses a problem when sending late select replies (CDEV_SEL2_REPLY),
because the object's minor number can not be used to identify the
device.  Since selecting on such objects through translated minor
numbers is actually required, we now save the minor number used to
initiate the select query in order to send a late reply.

The solution is suboptimal, as it is not possible to use two different
minors to select on the same object at once.  In the future, there
should be at least one select record for each minor that can be used
with each object.

8fea5ab8bd Kernel: make SIGKMESS target process list dynamic
The set of processes to which a SIGKMESS signal is sent whenever new
diagnostics messages are added to the kernel's message buffer, is now
no longer hardcoded. Instead, processes can (un)register themselves
to receive such notifications, by means of sys_diagctl().

3af30c2c60 ARM serial driver: Comment termios_baud_rate.
The B0-B115200 defines are flags, and not the actual speed they
represent.

This fixes an incoherency for B0 handling, and documents why it is
required to call the function again after changing the speed flag.

DFL_BAUD is set to one of the flag, so to translate it to an actual
speed, the function calls itself again, which will always be able to
finish without inducing another recursive call.

5e48dc3f40 TTY: skip /dev/log checks if console is serial
It is unclear why /dev/log has its own open/close rules, but those
rules conflict with serial console redirection.  This does not solve
the root of the problem, but it puts back in place more or less the
same workaround that was already in place before the TTY overhaul.

3d697930dd TTY: use libchardriver; clean up
- writing to a PTY master side blocks if there is not already a

- 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.

597151d963 libchardriver: full API rewrite
The new API now covers the entire character driver protocol, while
hiding all the message details. It should therefore be used by all
new character drivers. All existing drivers that already made use of
libchardriver have been changed to use the new API.

As one of the most important API changes, support for scatter and
gather transfers has been removed, as several key drivers already
did not support this, and it could be supported at the safecopy
level instead (for a future readv/writev).

Additional changes include:

- respond to block device open requests to avoid hanging VFS threads;
- add support for sef_cancel.

The block driver protocol and libblockdriver's bdr_ioctl hook are
changed, as well as the users of this hook. Other parts of the system
are expected to change accordingly eventually, since the ioctl(2)
prototype has been aligned with NetBSD's.

95624ae072 Block protocol: add user endpoint to IOCTL request
I/O control requests now come with the endpoint of the user process
that initiated the ioctl(2) call. It is stored in a new BDEV_USER
field, which is an alias for BDEV_FLAGS. The contents of this field
are to be used only in highly specific situations. It should be
preserved (not replaced!) by services that forward IOCTL requests,
and may be set to NONE for service-initiated IOCTL requests.

20173cb5d7 TTY: fix for PTY open/close logic
Opening and closing the master side of a pseudo terminal without
opening the slave side would result in the pseudo terminal becoming
permanently unavailable.  In addition, reopening the slave side
would be possible but not allow for I/O.  Finally, attempting to
open an in-use master would wipe its I/O state.  These issues have
been resolved.

97172a1db0 Sync char protocol: add nonblocking transfer flag
The async char protocol already has this, so this patch closes the
gap between the two protocols a bit. Support for this flag has been
added to all sync char drivers that support CANCEL at all.

The LOG driver was already using the asynchronous protocol, but it
did not support the nonblocking transfer flag. This has been fixed
as well.

cb5e2921b3 i2c: increase read/write timeout
The sht21 temperature and humidity sensor holds the i2c bus while
an ADC conversion is in progress. For example, a temperature
measurement is requested, a read operation is started, and the
sht21 doesn't respond to the read request until the result of
the measurement is ready. The conversion time isn't constant.
On rare occations (one in hundreds of samples) the timeout in the
i2c driver expires returning an error.

The example code from Sensirion, the sht21's manufacturer, suggests
a bus timeout of 1 second to accommodate the sht21. This commit
increases the bus timeout to 1 second. The timeout is only reached
when chips do not respond normally, so the change doesn't affect the
performance of any other drivers.

75bd3009d3 libi2cdriver: add functions for IC register access
Many i2c device drivers used similar code to access registers on
the ICs they drive. This commit implements that functionality in
libi2cdriver and updates the drivers to use the library instead of
their own register access functions. The net result is 375+ fewer
lines of code and less work for people developing new drivers.

The two exceptions were cat24c256 and parts of tda19988. They access
the bus in uncommon ways. It doesn't make sense at this time to
move their read/write functions into libi2cdriver.

f0c391e09b virtio-net: acknowledge used features
According to the virtio specifications, the host present the supported
features to the guest, and the guest should answer woth the features it
supports. This allows the host to disable support for features that the
guest is not going to use.

Minix tells to the host it doesn't support any extended features, while
it uses at least VIRTIO_NET_F_MAC and VIRTIO_NET_F_CTRL_VQ. For the
latter it seems it only allocate the queue while not using it later.
However starting with QEMU 1.4.0, with multiqueue support added, the
control queue is not allocated on the host side if the guest doesn't
tell it supports this feature. This cause virtio-net to crash on the
Minix side.

This patch fixes that by correctly telling the features that are
used by the Minix guest for more than printing a debug message. This
fixes virtio-net on QEMU 1.4.x.
