*MERGE* Merge from trunk (tags: th1-doc-vars)

Remove unused local variable from cgi_parse_POST_JSON() to fix a compiler warning. (tags: trunk)

Handle unreferenced footnotes. If a labeled footnote is defined but there are no references to it, then add a special item at the end of footnotes. This item includes a label and the text of the strayed footnote - both rendered verbatim via ... [More] html_escape(). Default skin makes such items visible and easily distinguishable. The order of such items match the order in the underlying source code. (tags: markdown-footnotes) [Less]

Cherrypicked [92221aaa192e82] and [7283ae6e120c10] on behalf of George. (tags: trunk)

Join duplicated footnotes slightly faster. Fix a comment about auxiliary cmp_footnote_id() function. (tags: markdown-footnotes)

Fix a misuse of an unsigned integer in the blobReallocMalloc() which can lead to redundant memory reallocations. (tags: markdown-footnotes)

Fix a bug in the blob_reserve() function that was introduced by [1243bf39996b8a]. The current mainline is not affected because this function is not used anywhere. However it was causing memory corruption on the 'markdown-footnotes' branch since it was employed in [544df852b2d9a1]. (tags: markdown-footnotes)

Display build/patch number for the MSVC compiler. (tags: trunk)

Fix compiler warning on builds that lack support for FuseFS. (tags: trunk)

Make the "fusefs" command and help text available, even on builds that lack support for FuseFS. (tags: trunk)
