Alessandro Decina 401ea5e848 aya, aya-obj: refactor map relocations 
Clearly split the code between `.maps`, `maps` and data maps (bss, data,
rodata). Sprinkle comments.

Remove MapKind which was effectively only needed since we used to have
one variant - BpfSectionKind::Data - to represent all data maps. Instead
add explicit BpfSectionKind::{Data, Rodata, Bss} variants and match on
those when we initialize maps.
Alessandro Decina 5c4f1d69a6 aya-obj: rework `maps` section parsing 
Avoid allocations and add comments explaining how things work.
Alessandro Decina bc8f4ef1c8 integration-tests: rename relocations to btf_relocations 
In preparation of adding actual ELF relocation tests

tests: use fedora 38 beta with testing repo
Tuetuopay 3655cd1e02 tests: use fedora 38 beta with testing repo 
Now that bpf-linker uses llvm 16, the easiest way is to use Fedora 38
Beta with the testing repos as they have it, without resorting to
Rawhide.

See https://packages.fedoraproject.org/pkgs/llvm/llvm/.

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.

We don't ever do ref-to-ref conversion for MapData so Borrow should

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.

aya-tool: remove outdated workaround
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Dmitry Savintsev 96b282d149 aya-tool: remove outdated workaround 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.
