Make recovery logic flexible about where objects end (fixes #573)

Don't assume endobj is at the beginning of the line. This means we are
looking at tokens for every line, but the odds of n n obj appearing in
the middle of the object are likely much lower than endobj not being
at the beginning of the line or missing entirely. This will probably
have a negative impact on recovery time for very large files.
Hopefully it will be worth it.

+	* Relax xref recovery logic a bit so that files whose objects are
+	either missing endobj or have endobj at other than the beginning
+	of a line can still be recovered. Fixes #573.
