Some of the examples make use of asprintf and strtol functions (to keep things simple) which are prohibited to use within our code (enforced by syntax-check). Therefore besides adding some examples, this patch also updates cfg.mk to exclude examples directory from asprintf and strtol rules, as well as updates .gitignore to exclude all the new admin binaries created in the 'examples' dir.
