James R. Barlow 517b385fe5 Work around loss of Unicode DOCINFO in Ghostscript 9.24+ 
Ghostscript no longer supports UTF-16-BE-hex strings as a way of
supplying Unicode data in pdfmark so we have lost this functionality too:
http://git.ghostscript.com/?p=ghostpdl.git;a=commit;h=e997c6836d243ab37fe3a5f0d57974af95eb5eac

For users this means setting --title, --author, etc. will not work if gs
9.24 is installed, but if the file has existing metadata it might work.

For now we enforce police-state-strict ASCII, until there's time to
implement proper metadata editing. Relevant tests set to xfail.

James R. Barlow 795019b0c1 Work around invalid TOC entries 
Kodak Capture Desktop and probably other software creates a
/Outlines entry with /First being set to an invalid indirect reference to
an object that hasn't been created. This is legal in the PDF spec but
problematic for qpdf. The objgen will be (max valid object ID + 1, 0).
Because we create new objects in _weave, some TOC entries will end
up assigned to new objects we create. Typically /ProcSet.

We solve the issue by refactoring page traversal and then doing it
twice, once to resolve all references (eliminating the null
reference problem) and a second pass to make our changes.

James R. Barlow 3aac3a98ca tests: Migrate metadata tests to pikepdf 
For some reason PyPDF2 has begun to trigger internal errors in
pytest on macOS alone. Not sure why, but nothing is wrong that I can
see. Seemed like an opportune time to switch to pikepdf; found some
new issues in the process anyway.

James R. Barlow 8013fd50da Draw preview image at full resolution 
As reported in #281 and confirmed by the test file in #279, downsampling
the preview adversely affects quality of image rotation especially for
small font sizes and marginal scans.

Full size gets rotation accuracy. This makes rotation a little inefficient
since it rasterizes twice - to be addressed later.

James R. Barlow bb50501369 ghostscript: never use autorotatepages 
It looks like from the gs manual that this parameter is only respected for

which it off.
