[Click] click-fastclassifier breaks alignment alignment

[rootkit85 at yahoo.it]

click-fastclassier generates code which produces _lots_ of unaligned
accesses on MIPS platform.
For example this code snippet:

FastClassifier_a_aeth::length_unchecked_push(Packet *p)
{
 const unsigned *data = (const unsigned *)(p->data() - 2);
 step_0:
 if ((data[3] & 0xffff) != 0x800)
   goto step_4;
[...]

is wrong even if the packet is properly aligned, as it starts reading
double words from a pointer which address %4 != 0
this could be easily fixed by using uint8 in the byte matching code.
As the fastclassifier tool is quite a lot of code, do you know any
fast way to change it in order to fix?

Thanks a lot,
