More robust handling of type errors
...
Give objects descriptions and context so it is possible to issue
warnings instead of fatal errors for attempts to access objects of the
wrong type.

Push QPDF member variables into a nested class
...
Pushing member variables into a nested class enables addition of new
member variables without breaking binary compatibility.

Enable finer grained control of stream decoding
...
This commit adds several API methods that enable control over which
types of filters QPDF will attempt to decode. It also adds support for
/RunLengthDecode and /DCTDecode filters for both encoding and
decoding.

Implement findFirst and findLast in InputSource
...
Preparing to refactor some pattern searching code to use these instead
of their own memchr loops. This should simplify the code that replaces
PCRE.

Security: replace operator[] with at
...
For std::string and std::vector, replace operator[] with at. This was
done using an automated process. See README.hardening for details.

Replace some assertions with std::logic_error
...
Ideally, the library should never call assert outside of test code,
but it does in several places. For some cases where the assertion
might conceivably fail because of a problem with the input data,
replace assertions with exceptions so that they can be trapped by the
calling application. This commit surely misses some cases and
replaced some cases unnecessarily, but it should still be an
improvement.

Security: avoid pre-allocating vectors based on file data
...
In places where std::vector<T>(size_t) was used, either validate that
the size parameter is sane or refactor code to avoid the need to
pre-allocate the vector.

Security: better bounds checks for linearization data
...
The faulty code was only used during explicit checks of linearization
data. Those checks are not part of normal reading or writing of PDF
files.

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.

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.
