Add libfuzzer style harness and cmake file

bshastry commented 5 years ago

Hello,

Since you are already fuzzing the rtsp parser, I thought it might be a useful addition to enrol this repo into the ossfuzz program.

This PR enables continuous fuzzing via https://github.com/google/oss-fuzz/pull/2895

The fuzzer quickly finds a memory leak in error parsing

Dear wds developers,

If you are interested in taking this forward, could you please provide a primary contact email address that I could use to enrol the project into ossfuzz? (please see https://github.com/google/oss-fuzz/pull/2895/files#r329091829)
