Dave Tucker ef0d1253ef fix(ebpf): Remove PerfEventArray::with_max_entries
This API doesn't make sense as the max_entries needs to be set to the
number of online CPUs by the loader.

Wouter Dullaert 7ad3926d99 feat(aya-ebpf): Implement memmove
The compiler will emit this function for certain operations, but aya
currently does not provide an implementation.
This leads to ebpf loading failures as the kernel can't find the symbol when
loading the program.

The implementation is based on https://github.com/rust-lang/compiler-builtins/blob/master/src/mem/mod.rs#L29-L40
and https://github.com/rust-lang/compiler-builtins/blob/master/src/mem/impls.rs#L128-L135
Only the simplest case has been implemented, none of the word optimizations,
since memcpy also doesn't seem to have them.

tyrone-wu 2d38b23b99 aya-ebpf/programs: moved ret from ProbeContext into new RetProbeContext
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.
