      Description

      In a recent code review, there was some discussion about when function returns should be compared against an explicit zero vs if (!func()). The answer is if the function is returning a boolean, but WT has mapped that to the int type for portability.

      However, C has had a bool type since C99 via <stdbool.h>, also supported by Visual Studio 2013 and above.

      Investigate converting WT to use explicit bool types to make it clear when expressions need to be compared against zero.
