doc: fixes for the xsltproc -> fop -> pdf toolchain
"Empty" <anchor> entities seem to trigger a bug in fop. These are
easily converted to reference on the containing block. Additionally,
<indexterm>'s seem to need to be inside a non-structural entity (like
a <para>) in order to determine their page number/location correctly.
