Use functions with prototypes when appropriate; NFC

2022-02-16T21:10:37+00:00

A significant number of our tests in C accidentally use functions
without prototypes. This patch converts the function signatures to have
a prototype for the situations where the test is not specific to K&R C
declarations. e.g.,

  void func();

becomes

  void func(void);

This is the twelfth batch of tests being updated (the end may be in
sight soon though).

[darwin] add support for __isPlatformVersionAtLeast check for if (@available)

2020-11-03T00:28:09+00:00

The __isPlatformVersionAtLeast routine is an implementation of `if (@available)` check
that uses the _availability_version_check API on Darwin that's supported on
macOS 10.15, iOS 13, tvOS 13 and watchOS 6.
