2018-02-13Change return value of GetAvailInputRyan Harrison
This changes the return value from uint32_t to FX_FILESIZE, which is the type the methods is uses return. The existing code does an unguarded static cast, so something like -1 could cause a very large value being returned. This change has a cascading impact up to the top of the progressive codec, which now has to handle negative values gracefully.

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.

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.
