* The i2c package can no longer be compiled as part of the lm_sensors tree
* The archive of the i2c package is removed
* smbus, i2c-dev and i2c-proc modules and headers have been removed; they
are now completely integrated into the i2c package
* The fake i2c.h header has been removed; this also allowed us to remove
the ugly LM_SENSORS and TBD defines.
* A new variable I2C_HEADERS is introduced in the Makefile. This allows
us to install the i2c headers in, for example, /usr/local/include/linux.
* All files now include <linux/i2c.h> instead of "i2c.h" and "smbus.h"
Status: 'make dep' works, all the right include files are found. 'make all'
does not yet work.
