Unify the implementation of strto{l,ul,ll,ull,imax,umax,q,uq} into one version for signed and one version for unsigned data types. Add a check for supported bases and set errno (userland) or panic (kernel, libsa) otherwise. Make strto{ll,ull,imax,umax} normal symbols and just keep the underscore versions as strong alias.
