Dave Tucker 79101e748a test: Replace RTF with Rust
This commit replaces the existing RTF test runner with a simple rust
binary package called - integration-test.

integration-test depends on integration-ebpf, which contains test eBPF
code written in Rust and C. `cargo xtask build-integration-test-ebpf`
can be used to build this code and supress rust-analyzer warnings. It
does require `bpf-linker`, but that is highly likely to be available to
developers of Aya. It also requires a checkout of `libbpf` to extract
headers like bpf-helpers.h.

Since everything is compiled into a single binary, it can be run
be run locally using `cargo xtask integration-test` or remotely using
`./run.sh` which re-uses the bash script from the old test framework
to spawn a VM in which to run the tests.

Alessandro Decina b66a73f6c7 Add aya-gen
aya-gen can be used to generate bindings for kernel types, eg:

	aya-gen btf-types ethhdr --probe-read-getters

Will generate:

	// ...

	#[repr(C)]
	#[derive(Debug, Copy, Clone)]
	pub struct ethhdr {
	    pub h_dest: [::aya_bpf_cty::c_uchar; 6usize],
	    pub h_source: [::aya_bpf_cty::c_uchar; 6usize],
	    pub h_proto: __be16,
	}

	impl ethhdr {
	    pub fn h_dest(&self) -> Option<[::aya_bpf_cty::c_uchar; 6usize]> {
		unsafe { ::aya_bpf::helpers::bpf_probe_read(&self.h_dest) }.ok()
	    }
	    pub fn h_source(&self) -> Option<[::aya_bpf_cty::c_uchar; 6usize]> {
		unsafe { ::aya_bpf::helpers::bpf_probe_read(&self.h_source) }.ok()
	    }
	    pub fn h_proto(&self) -> Option<__be16> {
		unsafe { ::aya_bpf::helpers::bpf_probe_read(&self.h_proto) }.ok()
	    }
	}
