Clean up compilation

Instead of mixing standard headers and internal redefinitions of standard
types, completely rely on the compiler for what is guaranteed for a free
standing environment. This results in the removal of kern/stddef.h and
kern/stdint.h. The kern/types.h header is reintroduced for the different
(and saner) purpose of defining types not specified in standard C,
namely ssize_t for now.
