Alessandro Decina a92bfebf50 aya: remove TryInto magic from program()/program_mut() too
For programs it's actually useful being able to get the underlying
Program enum, for example when iterating/loading all the programs

Alessandro Decina 42e0a659b2 aya: remove TryInto cleverness from map() and map_mut()
Require callers to call try_into() explicitly. It's more characters, but
it's easier to understand/document.

Also introduce MapError::NotFound instead of returning Result<Option<_>>.

everything.

Alessandro Decina 7ae3ddf2fa xtask: use aya-gen to generate the getters 4 years ago
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()
	    }
	}

Alessandro Decina 2cec04c578 bpf: add explicit BTF argument to the load API
Add a `target_btf: Option<Btf>` argument to Bpf::load. None can be
passed to indicate to skip BTF relocation, for example for kernels that
don't support it. Some(btf) can be used to pass BTF parsed with
Btf::from_sys_fs() or Btf::parse/parse_file.

Finally, add a simpler Bpf::load_file(path) that uses from_sys_fs()
internally to simplify the common case.
