This PR creates two new externally-facing APIs, uv_err_name_r() and uv_strerror_r(). In keeping with the precedent set by POSIX, the *_r() suffix of these two new methods indicate that the caller does the memory management and passes in the memory that the output will be stored in, which provides an alternative for the two existent methods (uv_err_name() and uv_strerror()), which, when called with an unknown error code, leak a few bytes of memory.
