abb53ac369 Limited inheritance to the attributes explicitly listed in the PDF spec 
Previous versions of qpdf incorrectly passed arbitrary objects from
/Pages objects down to individual pages in direct contradition with
the PDF specification.  These are now left in /Pages.  When
intermediate /Pages nodes are being discarded as when the /Pages tree
is being flattened, a warning is issued when unknown keys are
encountered.

43c404b45a Add QPDFObjectHandle::newStream(QPDF *, std::string const&) 
This makes the code simpler than having to create a buffer of a fixed
size and copy the string to it.

81e8752362 Use qpdf_offset_t in place of off_t in public APIs. 
off_t is used internally only when needed to talk to standard
libraries.  This requires that the "long long" type be supported by
the compiler.

5d4cad9c02 ABI change: fix use of off_t, size_t, and integer types 
Significantly improve the code's use of off_t for file offsets, size_t
for memory sizes, and integer types in cases where there has to be
compatibility with external interfaces.  Rework sections of the code
that would have prevented qpdf from working on files larger than 2 (or
maybe 4) GB in size.

b856379370 Portability issues: off_t, unlink 
New header qpdf/Types.h attempts to make sure size_t and off_t are
defined on any platform and in a way that would work with large file
support.  Additionally, missing header files are included to get
unlink.
