* Simplify names of some ebpf_result codes
* Remove _ERROR_ for consistency
* Combine EBPF_INVALID_HANDLE and EBPF_INVALID_OBJECT
* Rename EBPF_ERROR_NOT_FOUND to EBPF_KEY_NOT_FOUND for consistency with the associated description.
* Change code that returned EBPF_ERROR_NOT_FOUND for a case other than a
key, to use a different appropriate result, so the description stays correct.
