Alessandro Decina cb57d10d25 aya: rework links 
Remove LinkRef and remove the Rc<RefCell<_>> that was used to store
type-erased link values in ProgramData. Among other things, this allows
`Bpf` to be `Send`, which makes it easier to use it with async runtimes.

Change the link API to:

    let link_id = prog.attach(...)?;
    ...
    prog.detach(link_id)?;

Link ids are strongly typed, so it's impossible to eg:

    let link_id = uprobe.attach(...)?;
    xdp.detach(link_id);

As it would result in a compile time error.

Links are still stored inside ProgramData, and unless detached
explicitly, they are automatically detached when the parent program gets
dropped.

Dave Tucker 5d8b279265 aya: Fix BTF verifier output 
Currently errors can occur if the verifier output is > buffer as we get
ENOMEM. We should only provide a log_buf if initial load failed, then
retry up to 10 times to get full verifier output.

To DRY this logic it has been moved to a function so its shared with
program loading

Michal Rostecki 7e2fcd1d6d Support for fentry and fexit programs 
fentry and fexit programs are similar to kprobe and kretprobe, but they
are newer and they have practically zero overhead to call before or
after kernel function. Also, fexit programs are focused on access to
arguments rather than the return value.

Those kind of programs were introduced in the following patchset:

aya/aya-bpf: implement btf tracepoint programs 4 years ago
William Findlay 169478c863 Add support for raw tracepoint and LSM programs 
This change adds support for the following program types:

* raw tracepoint
* LSM

Supporting LSM programs involved a necessity of supporting more
load_attrs for the BPF_PROG_LOAD operation, concretely:

* expected_attach_type - for LSM programs, it has always to be set to
  BPF_LSM_MAC
* attach_btf_obj_fd - it's often used to reference the file descriptor of
  program's BTF info, altough in case of LSM programs, it only has to
  contain the value 0, which means the vmlinux object file (usually
  /sys/kernel/btf/vmlinux)
* attach_btf_id - ID of the BTF object, which in case of LSM programs is
  the ID of the function (the LSM hook)

The example of LSM program using that functionality can be found here:

Dave Tucker 9426f36f79 Implement Pinning For Programs and Maps 
This commit adds 2 new methods to aya::sys
- bpf_pin_object
- bpf_get_object

Which allow the pinning and retrieval of programs/maps to bpffs.

It adds a `Program.pin` API, such that a loaded program can be pinned.
For map pinning, the user must ensure the `pinning u32` in the
`bpf_map_def` is set to 1, maps will be pinned using a new builder API.

BpfLoader::new().map_pin_path("/sys/fs/bpf/myapp").load_file("myapp.o")

This will pin all maps whose definition requests pinning to path + name.

qdisc_detach_program can be used to detach all the programs that have
the given name. It's useful when you want to detach programs that were
attached by some other process (eg. iproute2), or when you want to
detach programs that were previously left attached because the program
that attached them was killed.

detaching. For older kernels, we just detach whatever is attached, which
is not great but it's the way the API worked pre XDP_FLAGS_REPLACE.
