Advanced JIT compilers and translators may want to use
eBPF verifier as a base for parsers or to perform custom

Add ability for external users to invoke the verifier
and provide callbacks to be invoked for every intruction

per-instruction pre-interpretation checks is added.  More
advanced users may also like to have per-instruction post
callback and state comparison callback.
