syzkaller is an unsupervised coverage-guided kernel fuzzer

* fuchsia: Fix the `extractor` tool. The include path in Zircon has changed; updated syz-extract/fuchsia.go to include this, and re-ran extract to get updated *.const files. * fuchsia: Update syzkaller to build with current Fuchsia API. Fuchsia doesn't have a stable API right now, so alas, this will probably continue to change until that's nailed down. But, useful to get this up-to-date at least. Relevant notes: * zx_channel_call_finish and _retry aren't technically public; leave them out until we have a less-cludgy way to expose them * musl supports setjmp/longjmp but not _setjmp/_longjump * remove some unsupported syscalls * update the build invocation |

syzkaller - kernel fuzzer
syzkaller is an unsupervised coverage-guided kernel fuzzer. Linux kernel fuzzing has the most support, akaros, freebsd, fuchsia, netbsd and windows are supported to varying degrees.

Documentation
Initially, syzkaller was developed with Linux kernel fuzzing in mind, but now it's being extended to support other OS kernels as well. Most of the documentation at this moment is related to the Linux kernel. For other OS kernels check: Akaros, FreeBSD, Fuchsia, NetBSD, Windows.
