2017-03-14Replace FX_FLOAT with underlying float type.Dan Sinclair

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.

2017-01-27Limit parsing recursion levels in CPDF_StreamParserNicolas Pena
We currently only limit the array recursion levels. This recursion level may also be reset when parsing. This is insufficient to protect against stack overflows.

2017-01-26Fix CSS fuzzer input sizeDan Sinclair
Currently we use the size provided by clusterfuzz when initializing the css syntax parser. This maybe incorrect as the CFX_WideString may have a different count after converting to UTF. Use the wide string length instead of the provided size. We need to guard against strings that convert to blank when doing the wide conversion so add an early exit.

2017-01-19Split fde/css files into individual class files.Dan Sinclair
This CL splits the files in xfa/fde/css into class per file and renames any needed files to match the class names. Update some of the classes to use std::stack.

2017-01-18Remove unused syntax parser initialize method.Dan Sinclair
This Cl removes the stream initializer from the FDE CSS parser. The only consumer was the css fuzzer. The fuzzer has been moved to use the string initializer to match the rest of the code.

We can remove a lot of "bOwnsStream" logic in the process.
