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.

Only partially optimize multipage.pdf so that it hopefully
improves speed of test suite without being useless as an
optimization test.

2131ad4670 Fix --remove-background error on PDFs with colormapped images 
It's unclear how exactly a
colormapped image gets to this
spot given the tendency of other
image processing tools to flatten
such images, but someone made it happen, so now we make sure
the image is okay.
