Subject: Remove unused IsContentUsedElsewhere()

Then CPDF_Object::GetDirectType() becomes unused.
Then GetIndirectType() becomes unused.
Then PDFPARSE_TYPEONLY becomes unused.
Then we can remove hideous casts of ints to ptrs.

Also, PDFPARSE_NOSTREAM is unused.
Then we can remove m_Flags from PARSE_CONTEXT.
