i2c(8) diagnostic tool for review

[Rafal Jaworowski]

This nice little program is helpful with inspecting an I2C bus, when bringing
up a new system, or just for diagnostic purposes:

Note the patch extends the /dev/iicX interface with a ioctl for the 'repeated
start' method.

More detailed description of the tool is in the manual page:

Any comments welcome.
