Branches:

lfn, master, serial, ticket/834-toolchain-update, topic/msim-upgrade, topic/simplify-dev-export

Message:

introduce atomic_count_t as the explicit type of the internal value in atomic_t (this is probably better than the chaotic mix of int/long)
atomic_count_t is defined as unsigned, for signed semantics you can cast it to atomic_signed_t
