f40ffc9d63 Pl_Flate: constructor's out_bufsize is now unsigned int 
This is the type we need for the underlying zlib implementation.

da30764bce Change QPDFObjectHandle::pipeStreamData's encode_flags type 
Change from unsigned long to int since we pass enumerated type values
to this field.

2efec4ce7b Fix C++ exception handling when -fvisibility=hidden (#302) 
Fix C++ exception handling when -fvisibility=hidden

Ensure that QPDFExc and QPDFSystemError are marked visible, so that their typeinfo will not be
suppressed when -fvisibility=hidden.

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.

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.

837dcf8fc2 Don't call assert while checking linearization data (fixes #209, #231) 
Instead of calling assert for problems found during checking
linearization data, throw an exception which is later caught and
issued as an error. Ideally we would handle errors more robustly, but
this is still a significant improvement.

a01359189b Fix dangling references (fixes #240) 
On certain operations, such as iterating through all objects and
adding new indirect objects, walk through the entire object structure
and explicitly resolve any indirect references to non-existent
objects. That prevents new objects from springing into existence and
causing the previously dangling references to point to them.
