The beginnings of i2c-dev

Everything is in, except the IOCTL hook (which will be pretty simple to add).
It compiles cleanly. It is not tested at all.

Also a very small fix for i2c-proc, and Makefile.

    11Many, many things. Most notably: 
    22 
     3* Fans give overflow if small values are written to them. 
    34* At least the bit-lp and bit-velle modules do no detection on loading; 
    45  ask Simon whether this is possible to add. 
    …… 
    1314  places, probably (everywhere where global vars are accessed). This must be 
    1415  done for the i2c modules, too. 
     16* Better general locking, or at least a once-over to check no race-conditions 
     17  remain. 
    1518* Make lm78.c detect 'double hits', (same chip connected to both SMBus and 
    1619  ISA). 
    1720* Better chip detection; insmod-time paramters to set addresses  
    1821  (difficult, because of all i2c busses!). 
     22* At least one case report that unused port addresses do not return 0xff 
    1923* Registrate which i2c addresses are used (a la ISA) for each adapter. 
    2024* Rename i2c-proc.c to i2c-user.c, and extend it with /dev entries;
