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.
Provide an `arg()` method in `RawTracepointArgs` wrapper of
`bpf_raw_tracepoint_args` and also in `RawTracepointContext`, so
it's directly available in raw tracepoint programs.
The methods and traits implemented here are unsafe. There is no
way to reliably check the number of available arguments, so
requesting a non-existing one leads to undefined behavior.
bpfman, a project using aya, has a requirement to support powerpc64 and
s390x architectures. Adding these two architectures to aya.
