Added more communication utils between userspace and kernel:

* Included maps and kernel ring buffer communication
* Extended the ebpf structure to include more modules
* New utils in both user and kernelspace
* Other changes
* This update precedes a great effort on researching and learning and linux kernel tracing and studing ebpfkit from defcon. More functionalities should come rather quickly now.
