245e086321 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.

Obtained from DragonFly, based on the wide char version from Citrus.
