2020-11-28 Jay Berkenbilt <ejb@ql.org>
* Add new functions to the C API for manipulating
QPDFObjectHandles. The new functions allow creation and
modification of objects, which brings a lot of additional power to
the C API. See include/qpdf/qpdf-c.h for details and
examples/pdf-c-objects.c for a simple example.

/* Object handling.
*
* These methods take and return a qpdf_oh, which is just an
* unsigned integer. The value 0 is never returned, which makes it
* usable as an uninitialized value.
*
* Each function below, starting with qpdf_oh, corresponds to a
* specific method of QPDFObjectHandler. For example,
* qpdf_oh_is_bool corresponds to QPDFObjectHandle::isBool. If the
* C++ method is overloaded, the C function's name will be
* disambiguated. If the C++ method takes optional argumens, the C
* method will have required arguments in those positions. For
* details about the method, please see comments in
* QPDFObjectHandle.hh. Comments here only explain things that are
* specific to the "C" API.
*
* Only a fraction of the methods of QPDFObjectHandle are
* available here. Most of the basic methods for creating,
* accessing, and modifying most types of objects are present.
* Most of the higher-level functions are not implemented.
* Functions for dealing with content streams as well as objects
* that only exist in content streams (operators and inline
* images) are mostly not provided.
*
* To refer to a specific QPDFObjectHandle, you need a pair
* consisting of a qpdf_data and a qpdf_oh, which is just an index
* into an internal table of objects. All memory allocated by any
* of these methods is returned when qpdf_cleanup is called.
*
* Regarding memory, the same rules apply as the above functions.
* Specifically, if a method returns a char*, the memory is
* managed by the library and, unless otherwise specified, is not
* expected to be valid after the next qpdf call.
*
* The qpdf_data object keeps a cache of objects returned by these
* methods. Once you are finished referencing an object, you can
* optionally release it. Releasing objects is optional since they
* will all get released by qpdf_cleanup, but it can help to
* reduce the memory footprint of the qpdf_data object to release
* them when you're done. Releasing an object does not destroy the
* object. All QPDFObjectHandle objects are deleted when they are
* no longer referenced. Releasing an object simply invalidates
* the qpdf_oh handle to it. For example, if you create an object,
* add it to an existing dictionary or array, and then release it,
* the object is safely part of the dictionary or array.
* Explicitly releasing an object is essentially the same as
* letting a QPDFObjectHandle go out of scope in the C++ API.
