m-holger 5e9de5cd50 Tune handling of sparse arrays in QPDF_Array 
Sparse arrays are rare. Dynamically create the variables needed to manage
them only when needed.

m-holger e6db8ddeba Change SparseOHArray index type to int and elements type to map 
There are no reasons other than historical to use size_t.
On balance, using map is more efficient. Hold shared pointers to
QPDFObjects rather than QPDFObjectHandles for consistencey with
QPDF_Array.

Jay Berkenbilt 18a583e8d9 Rename QPDFValueProxy back to QPDFObject 
QPDFValueProxy wasn't a good name for it. We decided the evil of
having the header file be named QPDFObject_private.hh was less than
the evil of having the class be named something other than what it
should have been named.

Jay Berkenbilt c7a4967d10 Change reset to disconnect and clarify comments 
I decided that it's actually fine to copy a direct object to another
QPDF. Even if we eventually prevent a QPDFObject from having multiple
parents, this could happen if an object is moved.

Jay Berkenbilt 264e25f391 Clear owning QPDF information for all objects, not just indirect 2022-09-08 10:19:38 -04:00
Jay Berkenbilt 6c61be00e8 Rename QPDFObject -> QPDFValueProxy 
This is in preparation for restoring a QPDFObject.hh to ease the
transition on qpdf_object_type_e.

This commit was created by
* Renaming QPDFObject.cc and QPDFObject.hh
* Replacing QPDFObject\b with QPDFValueProxy (where \b is word
  boundary)
* Running format-code
* Manually resorting files in libqpdf/CMakeLists.txt
* Manually refilling the comment in QPDF.hh near class Resolver

m-holger 9c86ba40d8 Fix commit 805c1ad : Reset QPDFValue::qpdf and QPDFValue::og when ... 
On destruction of the QPDF object replace all indirect object references
with direct nulls.

Remove all existing code to release resolved references.

Fixes performance issue due to interaction of resetting QPDFValue::qpdf and
og members and prior code.
