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 first batch of tests being updated (there are a significant
number of other tests left to be updated).
This commit adds supports for clang to remap macOS availability attributes that have introduced,
deprecated or obsoleted versions to appropriate Mac Catalyst availability attributes. This
mapping is done using the version mapping provided in the macOS SDK, in the SDKSettings.json file.
The mappings in the SDKSettings json file will also be used in the clang driver for the driver
Mac Catalyst patch, and they could also be used in the future for other platforms as well.
