/*
Returns the $qa_content structure for a question list page showing $questions retrieved from the database.
If $pagesize is not null, it sets the max number of questions to display.
If $count is not null, pagination is determined by $start and $count.
The page title is $sometitle unless there are no questions shown, in which case it's $nonetitle.
$navcategories should contain the categories retrived from the database using qa_db_category_nav_selectspec(...) for
$categoryid, which is the current category shown (set $categoryisfavorite to whether the user has favorited it).
If $categorypathprefix is set, category navigation will be shown, with per-category question counts if
$categoryqcount is true. The nav links will have the prefix $categorypathprefix and possible extra $categoryparams.
If $feedpathprefix is set, the page has an RSS feed whose URL uses that prefix.
If there are no links to other pages, $suggest is used to suggest what the user should do.
The $pagelinkparams are passed through to qa_html_page_links(...) which creates links for page 2, 3, etc..
