misc: Portable math_extras.h implementations. Add a <misc/math_extras.h> header file with portable implementations of a number of commonly used math and bit counting operations that are not available in the C programming language. The math_extras functions fall into two groups: 1. Unsigned integer arithmetic with overflow detection. Addition and multiplication are provides for the u32_t, u64_t, and size_t types. This commit doesn't include subtraction and division, and there are no signed operations. These could be added later if there is a need. 2. Bit-counting operations like clz, ctz, and ffs. These are provided for u32_t and u64_t only. I don't see a need for size_t operations, but they could be added if needed. A follow-on commit will add more efficient implementations using compiler builtins for those compilers that support it. Another commit will replace other uses of "naked" compiler builtins with calls to these functions.

cmake: tests: add cmake_minimum_required() to tests Adding cmake_minimum_required() as this is required by CMake. CMP0000 is a deprecated policy which allows to omit this function call, however doing so will result in CMake printing a warning. Adding cmake_minimum_required() to tests missing this call will remove the warning and also allow us to remove the policy setting.

misc: Always test the portable version of the math_extras.h functions. The implementation of the <misc/math_extras.h> functions will use the portable C code when PORTABLE_MISC_MATH_EXTRAS is defined before including the header. Use this feature macro to make sure that the unit test always tests the portable functions in addition to the ones using builtins for the current compiler.
