This change integrates fuzzing support for RtpDumps in WebRTC. This allows LibFuzzer to directly fuzz the RTP code path from packet arrival all the way to actual decoding and rendering. It does this by replaying each RTP packet in the RTPDump which can be mutated directly by the fuzzer. For fuzzing support the RtpFileReader needs to support reading from a buffer instead of an file. The test class requires FILE* for all its parsing operations and is deeply coupled this way. I chose to solve this problem at an OS level by using the tmpfile() option and copying the buffer to the tmpfile(). fmemopen() is no available on most platforms so couldn't be used as a generic solution. The additional copy isn't ideal but won't be a bottleneck for the fuzzing. In the future I plan for the fuzzers to read from a configuration file. But given the current packaging strategy for fuzzers in WebRTC this isn't easy.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.
Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.
The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.
