Our current limits.h only provides (U)INT_MAX constants. This patch adds most others expected by POSIX. Since some of these may be different depending on architecture (e.g. 'long' is 32-bit on x86 and 64-bit on arm64), provide a definition that will automatically figure out the right value for the data model the compiler is using (as long as it's using two's complement for signed integers, which I think we can assume these days).
