Dave Tucker 5d82d9a73e Add Tests 
This moves a large chunk of code from ebpf to shared so we can re-use
write_record_header and write_record_message and friends so that we
can write test cases to ensure that logs are properly formatted
given certain input.

Michal Rostecki 628b473e09 ebpf: Ensure the bounds of log buffer 
eBPF verifier rejects programs which are not checking the bounds of the
log buffer before writing any arguments. This change ensures that
written log arguments.

In practice, it means that doing this kind of checks is not going to be
needed in eBPF program code anymore:

Michal Rostecki ca1fe7e05f Format arguments in userspace 
This change moves away argument formatting from eBPF to the userspace.
eBPF part of aya-log writes unformatted log message and all arguments to
the perf buffer and the userspace part of aya-log is formatting the
message after receiving all arguments.

Aya-based project to test this change:
