Message:

Clean up headers

Depends on <limits.h> and <stdint.h> being provided, which is a step up from
depending on mostly undocumented predefined macros.
In principle, <limits.h> and <stdint.h> mostly describe properties of
the compiler, so even though we depend on certain values for their contents,
actually defining them in the library is kind of reversal of concerns.
