qdoc: Now reports duplicate page titles better.

Currently, qdoc reports duplicate pages, when it should be reporting
duplicate page titles. Sometimes the duplicate titles actually refer
to the same page, but often they are different pages with the same
title. This update changes the error message to better indicate that
two identical page titles were seen.

A further complication was that the qdoc warnings for these duplate
page title errors were useless when the duplicates were in different Qt5
modules, because the support for file location information in the qdoc
index files was inadequate. This update adds better location information
to each section in the index file. This makes the index files bigger
and will increase qdoc runtimes, hopefully not too much.
