Tidy QPDF_Stream
...
1. Make class final
2. Pass og parameter by value
3. Properly initialize qpdf and og
Also, tweak QPDF::replaceObject to allow stream replacement without
violating the requirement that streams must always be indirect objects.
Also, remove QPDF::reserveStream as it does not do what the name implies
and having this as a separate methods does not aid code readability.

Refactor the creation of unresolved objects
...
Create unresolved objects only for objects in the xref table (except during
parsing of the xref table). Do not add indirect nulls into the the object
cache as the result of a cache miss during a call to getObject except
during parsing or creation/updating from JSON. To support this behaviour,
add new private methods getObjectForParser and getObjectForJSON.
As a result of this change, dangling references are treated as direct nulls
rather than indirect nulls.

Add DCT decompression config methods in favor of compile-time changes
...
As a rule, we should avoid conditional compilation is it always causes
code paths that are sometimes not even seen lexically by the compiler.
Also, we want the actual code being fuzzed to be as close as possible
to the real code. Conditional compilation is suitable to handle
underlying system differences.
Instead, favor configuration using callbacks or other methods that can
be triggered in the places where they need to be exercised.
