We change `bcmul()` and `bcpow()` so that the result has exactly the requested scale (i.e. decimal places) to make them consistent with the other BCMath functions. This also changes our stance regarding bug #52748, which had been classified as documentation problem. We do not manipulate the numbers themselves (anymore), but rather introduce `bc_num2str_ex()` which accepts a scale parameter that overrides the scale of the number by omitting extraneous decimals and adding zeros, respectively. This also allows us to get rid of `split_bc_num()`, which fixes bug #75164 as well.
