Contains user-space functionality for doing
AF_XDP socket interactions. Much is copy-paste
from xdpilone, but with higher-level abstractions
put on top.
It should be usable at a high level without requiring
unsafe code on the library user's side. The more
low-level control is still available, for power users
who need that level of control (and accept the safety
implications).
Fixes: #507
bpfman, a project using aya, has a requirement to support powerpc64 and
s390x architectures. Adding these two architectures to aya.

This API doesn't make sense as the max_entries needs to be set to the
number of online CPUs by the loader.

Created retprobe.rs to hold RetProbeContext and moved the ret from
ProbeContext in probe.rs into RetProbeContext. Now, only kprobe (which
uses ProbeContext) can access args, and kretprobe (which uses
RetProbeContext) can access ret.
Fixes: #700

Pass an array of bytes instead of u64 to avoid clippy sign warnings.
