2017-06-19Make out_row_buffer an std::vectorNicolas Pena
The out_row_buffer of BMPDecompressor is made a vector. This forces the class to have constructor/destructor. Some other members were changed to be of size_t instead of int32_t.

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.

2017-05-31Move all of ccodec_bmpmodule state to its contextTom Sepez
This avoids a stale delegate pointer issue in the module. In theory, it should also allow for multiple decodes at the same time from different contexts within the same module, but this isn't used. Rename associated context, and use |new| to create it. Along the way, resolve a subtle FX_Alloc() vs. user-supplied callback free() issue, and remove supporting code.

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.

We can remove a lot of "bOwnsStream" logic in the process. Always pass these by const reference, in case the called method wants to hang on to the stream (one exception is where we stick a raw pointer into a void* slot in a context from another layer).
