bdf33c702a Importing sys/dev/videomode
NetBSD provides an in-kernel EDID parser, validator, and printer
along with other useful functions. This code will be re-used by
the Minix fb driver as it is a complete and well tested
implementation.

437177b028 i2c: increase BUFLEN/CMDLEN to 128, add page flag.
128 byte reads are much more common than 32 byte reads. The message
passing + setup/teardown for a read is much more expensive, in terms
of time, than the reading itself. A slightly bigger struct is well
worth the time savings. This reduces read times for /dev/eeprom
from 57 seconds per 4KB to 14 seconds.

Additionally, make sending the page address in the eeprom driver
and utility optional. This can save a little time when reading
within the same page and allows support for smaller devices that
don't support pages (example: chips containing EDID).

7f2d47d84c Remove libkern, leave just header.
Boot stuff dependencies from NetBSD.

Patch by Antoine Leca. Relocated to src/sys.

The port is using the same libminc.a as usual MINIX services (and does
not use NetBSD libkern); the headers imported from NetBSD sys/ tree
have been kept to a minimum (still numbers higher than 30 though.)

Note the peculiar way to use libraries (libsa, libi386, etc.): the
source code is shared, but each component builds its own copy of the
library, with its own set of preprocessor defines.
