Toke Høiland-Jørgensen b0536ce4ec lib: Add lib/util for adding utility library code

Add the directory and Makefile rules to prepare for storing library
functions in lib/util like we do in xdp-tools. With this, library code can
be added by just dropping the .c and .h into lib/util and updating
lib/util/util.mk with the object name.

Practical BPF examples

This git repository contains a diverse set of practical BPF examples that solve (or demonstrate) a specific use-case using BPF.

It is meant to ease doing rapid prototyping and development, writing C-code BPF programs using libbpf. The goal is to make is easier for developers to get started coding.

Many developers struggle to get a working BPF build environment. The repo enviroment makes it easy to build/compile BPF programs by doing the necessary libbpf setup transparently and detect missing compile dependencies (via the (configure)[configure] script). It is a declared goal to make BPF programming more consumable by detecting and reporting issues (when possible).
