api: provide 32-bit friendly argument comparison macros
We have a longstanding issue with 32-bit to 64-bit sign extension
inadvertently resulting in bogus syscall argument extensions. This
patch introduces a new set of argument comparison macros which
limit the argument values to 32-bit values so that we don't run into
problems with sign extension.
We use the macro overloading proposed by Roman at
https://kecher.net/overloading-macros/ to retain the feature of these
macros being usable as static initializers.
Thanks to @jdstrand on GitHub for reporting the problem.
