38a6cf8866 Update binary compatibility test instructions 
Since autogenerated files are now committed, we no longer need to
rerun ./autogen.sh and actually shouldn't because it could mask
errors.

eb49e07c0a Make inline image token exactly contain the image data 
Do not include the trailing EI, and handle cases where EI is not
preceded by a delimiter. Such cases have been seen in the wild.

2b6c79bcae Improve locating inline image's EI 
We've actually seen a PDF file in the wild that contained EI
surrounded by delimiters inside the image data, which confused qpdf's
naive code. This significantly improves EI detection.

ec9e310c9e Refactor QPDFTokenizer's inline image handling 
Add a version of expectInlineImage that takes an input source and
searches for EI. This is in preparation for improving the way EI is
found. This commit just refactors the code without changing the
functionality and adds tests to make sure the old and new code behave
identically.

31372edce0 Inline image token value ends with EI, not delimiter 
The inline image token erroneously included the delimiter that
followed EI. The ObjectHandle created from it was correct.

8d229e078f Improve info message in optimize images (fixes #280) 
When qpdf can't optimize an image because of an unsupported color
space, state this specifically. Recognize that many valid colorspaces
are not represented as name objects.

52f9d326a5 Resolve duplicated page objects (fixes #268) 
When linearizing a file or getting the list of all pages in a file,
detect if the pages tree contains a duplicated page object and, if so,
shallow copy it. This makes it possible to have a one to one mapping
of page positions to page objects.

65ef0bf313 When flattening, remove annotations with no appearance stream 
With the exception of form field annotations when /NeedAppearances is
true, remove annotations that don't have appearance streams when
flattening. There is no reason to keep these when flattening since
they are invisible. This may include unchecked checkboxes, unshown
popup windows, etc.

c2030d1f33 Implement password recovery suppression and password mode (fixes #215) 
Allow fine control over how passwords are encoded for writing, and
allow password for reading to be given as a hexademical encoded
string. Allow suppression of password recovery as a means to ensure
that the password you specify is actually the right one.
