xmlsecurity: implement removal of a signature in pdfverify

Desktop / LibreOffice - Miklos Vajna [collabora.co.uk] - 21 October 2016 11:19 UTC

It's not exactly clear how one should guess what was file end before signing, for now assume the followings:

- the file ended with a %%EOF, an optional \r, and a \n- the number of incremental updates is the same as the number of signatures

When the later is not the case, don't attempt to remove the signature.
