Hi,

I've committed the attached patches.

o The change to sid.scm allows for the reading of the final 24 bits of 
an insn beyond the base. This happened with an internal port which has a 
32 bit base and has some 56 bit insns.

o The change to utils-gen.scm corrects a problem for ports with insns of 
length less than the base.  -gen-ifld-extract uses its second argument 
to generate
the 'total' argument to EXTRACT_{LM}SBO_[U]INT which expects it to be 
the width of the base insn word. Using (min base-length total-length) is 
not correct in this situation. base-length seems to be the correct value.

o The change to utils.scm is simply to update the generated copyright years.
