Dave Tucker de4905a24b aya: Add loaded_programs() API to list all loaded programs 
This uses a Programs iterator to yield all loaded bpf programs using
bpf_prog_get_next_id.

aya: Fix is_perf_link_supported
Dave Tucker ce79de7ff6 aya: Fix is_perf_link_supported 
This was mistakenly comparing the exit code of the syscall, which is
always -1 and not the corresponding error-code. Added unit tests to
ensure we don't regress.

Merge pull request from dave-tucker/perf_link 
Use bpf_link for perf_attach programs (Kprobe/Uprobe/Tracepoint etc...)
Dave Tucker 7479c1dd6c aya: More discrete feature logging 
Just use the Debug formatter vs. printing a message for each probe.

Dave Tucker a18693b42d aya: Add support for multibuffer programs 
This adds support for loading XDP programs that are multi-buffer
capable, which is signalled using the xdp.frags section name. When this
is set, we should set the BPF_F_XDP_HAS_FRAGS flag when loading the
program into the kernel.

Dmitry Savintsev 96b282d149 aya-tool: remove outdated workaround 
The comment says that `.derive_debug` was needed as
a workaround for https://github.com/rust-lang/rust-bindgen/issues/2083.
This issue is now closed, and aya-tool compiles without derive_debug.

Additionally, update bindgen dependency to 1.64.

Merge pull request from dave-tucker/program-from-pinned3 
aya: Add from_pin for Programs
Dave Tucker 7a720ab0c1 aya: Add from_pin for Programs 
This commit adds from_pin() which allows the creation of a Program
from a path on bpffs. This is useful to be able to call `attach` or
other APIs for programs that are already loaded to the kernel.

This differs from  since it implements this on the concrete program
type, not the Program enum, allowing the user to pass in any additional
context that isn't available from bpf_prog_info.

Support BTF key/value specification for all maps 
Fix a bug which was resulting in `ENOTSUPP` following
the `BPF_MAP_CREATE` Syscall.  This fix was initially
found by libbpf maintainers in:
https://github.com/libbpf/libbpf/issues/355.

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
