- CPDF_SyntaxParser can no longer be initialized multiple times.
- Make the file length and header offset const.
- Make the header offset type FX_FILESIZE consistently.
- Simplify for the common case where the header offset is 0.

This enables more complicated cleanup when an observed object
is destroyed. Use it to make documents observable and to allow
the CPDF_Avail to cleanup without the need for intermediate class.

Improve CPDF_Document interface.
Fix relationship between CPDF_Document and CPDF_Parser.
This CL changes CPDF_Document to internally create the CPDF_Parser
and removes the need for the CPDF_Parser to know about the CPDF_Document.

We can use 'Prev' value of first-page cross-reference table trailer
for load main cross-reference table,
instead of 'T' value of Linearized header (Offset of first entry in main cross-reference table).
This is better solution, because this is allow us check entry count in main cross-ref table and
unify loading of main cross-ref table with loading methods of non linearized document.
