Greatly minimize the impact between going back and forth from
XFA being on/off, so that XFA case is just an extension beyond
the non-XFA data structures we've shipped for years, instead of
being a complete replacement of them.

Similar tp CPDF_Document::Extension, this is a base type for fpdfsdk/
to use to improve layering.
While we're at it, make pages point to documents to prove they don't
outlive them.
Another small step towards not passing XFA objects across FPDF.

Track the decode state in one data structure. Also grab pointers to data
structure members before tight loops when decoding. It turns out
referring to this->foo in tight loops can actually slow down decoding.

Should FPDFDocumentFromCPDFDocument() be called several times under
XFA, we may WrapUnique() the document several times. So cache a pointer
back from CPDF_Document to CPDFXFA_Context to avoid this.
Because of layering, introduce a placeholder type CPDF_Document::Extension.
This is actually the first step in some larger XFA ownership cleanup, but
makes a nice standalone CL around the one particular issue.

GIF extensions are laid out as follows: <size byte> <chunk of data>
<size byte> <chunk of data> ... <terminator byte>. The decoder needs
to scan along the data, finding the size bytes to determine where
the block ends in the stream, even if we don't care about the
content. Currently the decoder is storing all of the data chunks,
which are never used and take a lot of time to concat together if
they are very small.
Our implementation of the GIF spec does not handle this extension, so
when scanning for the end of the block, just don't bother storing
data from it.
