Refactor Xref_table::reconstruct
...
Split reconstruction into two passes - scanning of input for objects and
insertion of objects into the xref table. This allows insertion to take
place in the usual reverse order and removes the need for a separate
insert_reconstructed method.

Fix handling of hybrid reference files in QPDF::read_xrefTable
...
QPDF::read_xrefTable ignores type 0 entries for objects in a section if an
associates XRefStm has an entry for the same object.
The spec states:
When the conforming reader searches for an object, if an entry is not
found in any given standard cross-reference section, the search shall
proceed to a cross-reference stream specified by the XRefStm entry
before looking in the previous cross-reference section,
If a deleted entry is found in a section, the XRefStm is not searched
according to the standard.
