Jay Berkenbilt f45dacf4cb 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.

Jay Berkenbilt 4a648b9a00 Fix bug in merging resources /DR from foreign AcroForm (fixes #548) 
When making resources indirect in from_dr, the code was using the
wrong owning QPDF, forgetting that from_dr had already been copied
using CopyForeignObject.

Jay Berkenbilt 9b28933647 Check object ownership when adding 
When adding a QPDFObjectHandle to an array or dictionary, if possible,
check if the new object belongs to the same QPDF. This makes it much
easier to find incorrect code than waiting for the situation to be
detected when the file is written.

Jay Berkenbilt 33a47d5c3c Make QPDF::findPage public (fixes #516) 
This was originally not public because I wanted to get rid fo the
pages cache, but I recently realized there were deep reasons not to do
that, and the author of pikepdf wanted this, so I decided to make it
public.

Fredrik Fornwall e0775238b8 Fix QPDFEFStreamObjectHelper::{get,set}Subtype 
The /Subtype entry that specifies the mime type of an embedded file is
inside the embedded file stream dictionary directly, not it in the
parameter dictionary.

Jay Berkenbilt a77f58142d Remove some assertions that are not necessarily true (fixes #514) 
Operations that add the same object to multiple places in the pages
tree are throwing exceptions and then later causing assertion
failures. The assert calls shouldn't be there.
