Define integer limits independently from the system definitions.
In 83ff1618 we defined integer limits iff they're not provided by the system. That turns out not to be the greatest idea because there's different ways some datatypes can be represented. E.g. on OSX PG's 64bit datatype will be a 'long int', but OSX unconditionally uses 'long long'. That disparity then can lead to warnings, e.g. around printf formats.
This commit has added PG_INT16_MIN/MAX, however we still rely on SHRT_MIN and SHRT_MAX in some code paths. On all the platforms I looked at (OpenBSD, FreeBSD, MinGW, MSVC, OSX, Linux, Solaris) SHRT_MIN and SHRT_MAX definitions are always the same. Still, shouldn't we replace SHRT_* by their equivalent PG_INT16_* to be completely independent? I am just wondering if you considered that.
