yay!  I finally fixed a bug! (sheesh, bad day).

The device table is not null-terminated so we run off the end during
matching and go oops.

I also moved all the statics out of i810_main.h and into i810_main.c. 
There is not a lot of point putting them in a header file: if any other .c
file includes the header we get multiple private instantiatiations of
all that stuff.
