Enums now carry a signed bit in the info flags. Take it into account
when applying enum relocations.

Michal Rostecki 6ad2c3c373 aya-bpf-macros: Allow to make programs public
Allow to define programs as public functions (even in library crates)
and then import them.

For example, we can have library crate with `libfoo/src/lib.rs`
containing:

```rust
pub fn my_xdp_program(ctx: XdpContext) -> u32 {
    xdp_action::XDP_PASS
}
```

And then a binary importing it:

```rust
pub use libfoo::my_xdp_program;
```

This way, commonly used eBPF programs can be distributed as lib crates.

Tested with: https://github.com/vadorovsky/aya-examples/tree/main/pub-progs

- Rename `new_tc_link` to `attached`
- Simplified example for `attached`

The following was not requested in reviews:
- Moved example from `SchedClassifierLink` tor
  `SchedClassifierLink::attached' since we're only showing an
  example of that one method

Andre Fredette f46fd17cc3 Support reconstruction of `SchedClassifierLink`
This is the proposed solution for Step 2 of issue #414

“For cases where you have done program.take_link() to manage
ownership of TcLink we need an API similar to PinnedLink::from_pin
that can reconstruct a TcLink”

As long as a user application continues to run after executing
`take_link()`, the `SchedClassifierLink` returned can be used to
detach the program.  However, if we want to handle cases where the
application exits or crashes, we need a way to save and reconstruct
the link, and to do that, we also need to know the information
required for the reconstruction -- namely, the `interface`,
`attach_type`, `priority`, and `handle`.  The user knows the first
two because they are required to execute `attach()` in the first
place; however, the user will not know the others if they let the
system choose them.

This pr solves the problems by adding an `impl` for
`SchedClassifierLink` with an accessor for `tc_options` and a `new()`
function.

Michal Rostecki 75336e5a35 integration-test: Fix the kernel version chceck for smoke test
Before this chane, the check was always negative if the minor version
was less then 9. So, for example, the smoke test was skipped for kernel
6.1:

```
skipping as 6.1 does not meet version requirement of 5.9

Matteo Nardi 3000949bcc Remove libbpf dependency from relocation tests
Simplifiy the relocation tests build process by removing the need for libbpf
at runtime. Its usage is replaced with local `__builtin_*` attributes.
This removes the need for the `LIBBPF_INCLUDE` env variable.
