Pass section when available to bfd_octets_per_byte

and other tidies.  I think it's better to default to passing the
section to bfd_octets_per_byte, even in cases where we know it won't
make a difference.

A number of the coff reloc functions used bfd_octets_per_byte wrongly,
not factoring it into the offset into the data buffer.  As it happens,
the targets using those files always had bfd_octets_per_byte equal to
one, so there wasn't any detectable wrong behaviour.  However, it is
wrong in the source and might cause trouble for anyone creating a new
target.  Besides fixing that, the patch also defines OCTETS_PER_BYTE
as one in target files where that is appropriate.
