2017-06-01Move CCodec_GifModule state to CGifContextTom Sepez
Introduce a base CCodec_GifModule::Context class with a virtual destructor so holders of unique_ptr's to these can delete them without actually having any knowledge of the implementation details of the context.

2017-05-23Remove longjmp from the Gif moduleNicolas Pena
The Gif module is only using the longjmp as a way to catch errors, so this CL makes it use GifDecodeStatus::Error instead.

2017-05-11Do not use vector data() when it is emptyNicolas Pena
Before, all pointers were being initialized to 0. After raw pointers were changed to vectors, data() was used in some cases, but now no longer returns nullptr when it is supposed to. This CL fixes that.

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.

2017-03-01Create virtual codec APIs so chrome/fuzzers can link separatelyTom Sepez
The one step to make an actual concrete class is conditionalized in fpdfview and is unconditional in the fuzzer. Also replace the clumsy C-style callbacks with a delegate interface as long as we are making new interfaces.

2017-02-27Allow building XFA without additional codecs.Tom Sepez
This is something we'd like to try for initial XFA launches adding in codecs as justified by results in the wild. Adding statistics for the unsupported cases is a follow-up exercise once this builds correctly. We always build all the additional libraries, to allow fuzzers to link against them even if we are not shipping them. The linker will sort it out for the actual code. Rename some files to match the classes contained within. That the existing tests seem to pass with the codecs disabled warrants further investigation.
