Add Major, Minor and Mkdev functions for converting devices numbers to
their major/minor components and vice versa.
The functions follow the behavior of the macros defined in DragonFlyBSD's
sys/types.h header. However, the parameter and return types are changed
to match the existing implementations of these functions.
Test the conversion macros with some well-known device numbers.
