Regularize band writer interface.
We have various functions that, for different image formats,
write a header, then a band, then (sometimes) a trailer.
Push them all through a single interface.
This change also fixes potential problems caused by the trailer
writing being an implicit destructor, which can cause problems
in cleanup code if the trailer writing throws an error.
