Dave Tucker 0c25d8655e 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 ec31526de1 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:
