stdlib: Add new random functionality/module
The old random module contains an old algorithm which have flaws and the api requires the user to invoke seed and or checking if seed have been invoked, if a non constant seed is to be used. The api contains the following features: - The user can invoke rand:unform/[0|1] directly and get a non constant seeding. - The api is split in functional and non functional functions, i.e. usage of _s functions will not affect the process dictionary. - The api contains several algorithms with different characteristics and can be extended with new algorithms in the future. - Contains state of the art random number generators. - Default algorithm is taylor made for erlang to be fast on 64bits machines.
