Update annotation handling in preparation for incremental update

When incremental update is in place, functions that alter one structure may
have the side-effect of altering another: i.e., updating an annotation may
require the Annots array or even the page to be cloned. This commit makes
the existing annotation code hardy to this eventuallity. It also cleans up
a slight mess of the past where not all annotation-altering functions had
access to the pdf_annot struture, instead having to work with just the
pdf object.
