Optimize ManPage plugin's parsing of section contents.

To find a page, we only need the identifier and the section ID.
That is enough to construct the KUrl on demand - no need to keep
thousands of them in memory.
Greatly optimize the ManPageModel.

Instead of loading huge HTML files for the individual sections, we
simply use KIO::listDir and use its results.

Sadly, we cannot do the same for the top-most page as a listDir
on man:// returns not only the folders but also all entries...
Reformat sources
Also use listDir for the initial section parsing and cleanup code.

This mostly simplifies the code logic but also gives us more
sections than the HTML variant. Sadly, there is no way to filter
KIO data on the remote site yet, so this is a bit slower than before
as all other entries will be returned here as well.
