    Rework pdf_lexbuf to allow for dynamic parsing buffers.
    
    Currently pdf_lexbufs use a static scratch buffer for parsing. In
    the main case this is 64K in size, but in other cases it can be
    just 256 bytes; this causes problems when parsing long strings.
    
    Even the 64K limit is an implementation limit of Acrobat, not an
    architectural limit of PDF.
    
    Change here to allow dynamic buffers. This means a slightly more
    complex setup and destruction for each buffer, but more importantly
    requires correct cleanup on errors. To avoid having to insert
    lots more try/catch clauses this commit includes various changes to
    the code so we reuse pdf_lexbufs where possible. This keeps the
    speed up.
