-dSAFER disables certain scary features of ghostscript
(like arbitrary file access). Its primarily about postscript
security, but enable it for pdfs to be safe.

Everything is properly escaped so it doesn't matter, but as an
extra bit of safety, cast width/height/page to int, in order to
ensure under no circumstances would something unexpected be fed
to ghostscript.

Pass the newly added param to the next function to get it passed to

This change causes wiki syntax like
[[File:Foo.pdf|thumb|Page 7 of document]]
to be interpreted as a caption instead, of saying select page 7
of the pdf. Previously it eventually ran intval( '7 of document' ),
so flipped to page 7.
Only possible downside I could see is this would cause things like
left-to-right marks and weird unicode spaces to no longer be ignored.
I don't think that's a big deal.

Ensure all shell arguments are escaped individually.
This relies on Ica8e37d1c1bea3b68c0165109aa7b9330fe9128a.

This code was left over and forgotten about from my gsoc project
back in 2010 (made minor modifications)
(note about message named: they start with "exif-" to be compatible
built in metadata code, which uses that prefix to be compatible with
the older messages).

* remove no longer accurate code comment
* set default values for the processor commands, otherwise it's totally confusing that not only doesn't it work, but it looks like it's just not installed
* added a comment about adding to $wgFileExtensions -- not doing it automatically since some wikis might want to *use* PDFs from a shared server without locally uploading them.... mebbe... dunno... keeping this one open for now. ;)
* Use a nice simple PHP array instead of constructing unnecessary XML. This removes the dependency on PHP 5.1.3 for a SimpleXML method.
* Tell pdfinfo to give us metadata encoded in UTF-8. If we start outputting title and creator info this will be nice!
* Tell pdfinfo to give us page size information for all pages (at least through page 99999 :) rather than just the first page
* Make use of that per-page size information so we can properly render pages of differing size. Without this, they get stretched or squooshed in interesting days.
* Rename the pdf_no_xml message to pdf_no_metadata (in English)
