2017-05-09Cleanup of CGifDecompressor part 1Nicolas Pena
This CL changes the tag_gif_decompress_struct into CGifDecompressor. It cleans up a bunch of unnecessary function pointers and starts cleaning up the members of the new class.

2017-05-09Move FPDF_FILEWRITE adapter to own fileDan Sinclair
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.

2017-05-08Check bits to decode will fit before decodingDan Sinclair
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.

2017-05-06core: allow building against system zlibMiklos Vajna
In a way similar to the existing USE_SYSTEM_LIBJPEG. The default is of course still the DEPS-based zlib checkout. Changes in v2: 1) Since Chromium doesn't have //third_party:zlib (AKA a "zlib" target in //third_party/BUILD.GN) all the targets that depended on //third_party:zlib now depend on third_party:zlib, which always points to PDFium's third_party/BUILD.GN. The targets that depended on //third_party:zlib in third_party/BUILD.GN just depend on :zlib instead. 2) Move the zlib bits out of !build_with_chromium block.
