This makes a variety of small changes to synchronize bits of code using different types, remove useless code or casts, and add explicit casts in some places previously doing implicit ones. For example: * Change a few type declarations to better match how the majority of code uses those objects. * Eliminate "< 0" check for unsigned values. * Replace "(float)sin(x)", where |x| is also a float, with "sinf(x)", and similar. * Add casts to uint32_t in many places timestamps were used and the existing code stored signed values into the unsigned objects. * Remove downcasts when the results would be passed to a larger type, e.g. calling "foo((int16_t)x)" with an int |x| when foo() takes an int instead of an int16_t. * Similarly, add casts when passing a larger type to a function taking a smaller one. * Add casts to int16_t when doing something like "int16_t = int16_t + int16_t" as the "+" operation would implicitly upconvert to int, and similar. * Use "false" instead of "0" for setting a bool. * Shift a few temp types when doing a multi-stage calculation involving typecasts, so as to put the most logical/semantically correct type possible into the temps. For example, when doing "int foo = int + int; size_t bar = (size_t)foo + size_t;", we might change |foo| to a size_t and move the cast if it makes more sense for |foo| to be represented as a size_t.
