This Cl moves the adapater out of the fpdfsave.cpp file into its own
h/cpp files. The adapter was renamed for clarity. The CPDF_Creator was
modified to take the adapter as a constructor param and the Create
methods consolidated.

When decoding the CPDF_HintTable we read the dwDeltaGroupLen value out
of the input stream which is a 16bit number. That value is then passed
in to read a uint32_t of the object number. If we have a group length of
> 32 bits we'll cause an undefined shift when we attempt to shift right
more then 32 bits.
This Cl bails out early if the dwDeltaGroupLen value is > 32 in order to
stop the undefined shifts.

This CL applies several fixes to the fallback font code.
- PDFium uses -1 to indicate that no glyph index was found, but freetype uses
0. In CPDF_TrueTypeFont, an index of 0 indicates a freetype failure, which
means we should try to find the glyph from a fallback font.
- Improve the fallback glyph calculation by going from original font charcode
to unicode to fallback font charcode.
- Consider the m_ExtGID on Mac when deciding the fallback.
