We have previously tried to import traits anonymously where possible but
enforcing this manually was hard.
Since Rust 1.83 clippy can now enforce this for us.

Change FromRawTracepointArgs::arg to return T rather than *const T which
seems to have been returning a dangling pointer.
Arguably this is not strictly necessary; edition 2024 seems to be
focused on increased strictness around unsafe code which doesn't unlock
new functionality for our users. That said, this work revealed an
apparent bug (see above) that we wouldn't otherwise catch due to
allow-by-default lints.
This removes the fake std module in aya-obj which is no longer needed as
thiserror now properly supports no_std.

bpfman, a project using aya, has a requirement to support powerpc64 and
s390x architectures. Adding these two architectures to aya.

When comparing `local_spec` with `target_spec` for enum relocations,
we can encounter a situation when a matchinng variant in a candidate
spec doesn't exist.
Before this change, such case wasn't handled explicitly, therefore
resulted in returning currently constructed `target_spec` at the
end. The problem is that such `target_spec` was, due to lack of
match, incomplete. It didn't contain any `accessors` nor `parts`.
Later usage of such incomplete `target_spec` was leading to panics,
since the code operating on enums' `target_spec` expects at least
one `accessor` to be available.
Fixes#868
This fix aya wrong logic causing non entrypoint functions to not have
any BTF relocations working.
Also fix missing section_offset computation for instruction offset in
multiple spots.
This fixes `cargo build --all-features` by sidestepping the feature
unification problem described in The Cargo Book[0].
Add `cargo hack --feature-powerset` to CI to enforce that this doesn't
regress (and that all combinations of features work).
Since error_in_core is nightly-only, use core-error and a fake std
module to allow aya-obj to build without std on stable.

The crate has few libstd dependencies. Since it should be platform-
independent in principle, making it no_std like the object crate would
seem reasonable.
However, the feature `error_in_core` is not yet stabilized, and the
thiserror crate currently offers no no_std support. When the feature
no_std is selected, we enable the `error_in_core` feature, switch to
thiserror-core and replace the HashMap with the one in hashbrown.
To split the crate into two, several changes were made:
1. Most `pub(crate)` are now `pub` to allow access from Aya;
2. Parts of BpfError are merged into, for example, RelocationError;
3. BTF part of Features is moved into the new crate;
4. `#![deny(missing_docs)]` is removed temporarily;
5. Some other code gets moved into the new crate, mainly:
- aya::{bpf_map_def, BtfMapDef, PinningType},
- aya::programs::{CgroupSock*AttachType},
The new crate is currenly allowing missing_docs. Member visibility
will be adjusted later to minimize exposure of implementation details.
