a478cbb6dc Silently/transparently recognize UTF-16LE as UTF-16 (fixes #649) 
The PDF spec only allows UTF-16BE, but most readers seem to accept
UTF-16LE as well, so now qpdf does too.

fbd3e56da7 Ignore -- at the top level arg parser (fixes #652) 
This was unintended behavior that was added back for backward
compatibility. It is intentionally undocumented.

1065bbb016 Handle odd PDFDoc codepoints in UTF-8 during transcoding (fixes #650) 
There are codepoints in PDFDoc that are not valid UTF-8 but map to
valid UTF-8. We were handling those correctly with bidirectional
mapping.

However, if those same code points appeared in UTF-8, where they have
no meaning, they were left as fixed points when converting to PDFDoc,
where they do have meaning. This change recognizes them as errors.

9044a24097 PointerHolder: deprecate getPointer() and getRefcount() 
Use get() and use_count() instead. Add #define
NO_POINTERHOLDER_DEPRECATION to remove deprecation markers for these
only.

This commit also removes all deprecated PointerHolder API calls from
qpdf's code except in PointerHolder's test suite, which must continue
to test the deprecated APIs.

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.

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.

detecting unreferenced resources in pages and also sets the stage for

fc88837d4b Treat /EmbeddedFiles as a proper name tree 
If we ever had an encrypted file with different filters for
attachments and either the /EmbeddedFiles name tree was deep or some
of the file specs didn't have /Type, we would have overlooked those as
attachment streams. The code now properly handles /EmbeddedFiles as a
name tree.

a139d2b36d Add several methods for working with form XObjects (fixes #436) 
Make some more methods in QPDFPageObjectHelper work with form
XObjects, provide forEach methods to walk through nested form
XObjects, possibly recursively. This should make it easier to work
with form XObjects from user code.
