Removed some compiler warnings

All our own code (ie. anything not in the i2c directory) compiles now without
warnings, even with WARN=1 (which sets -Wall -Wstrict-prototypes -Wshadow
-Wpointer-arith -Wcast-qual -Wcast-align -Wwrite-strings -Wnested-externs
-Winline). There is one exception: the lex code (conf-lex.l) complains about
unused functions. That's flex' fault, not ours!

The i2c code still emits many warnings with the above flags; that's Simon's
problem.
