nextpow2.m: Overhaul function for improved accuracy and Matlab compatibility (bug #65441) * nextpow2.m: Clarify documentation. Document return value of special input 0. Add input validation to exclude complex inputs. New algorithm for computing nextpow2 based on 2-output form of log2(). Use cast() to have output class match input class for Matlab compatibility. Add BIST tests. * NEWS.10.md: Announce changes to nextpow2 function.

 - `nchoosek` algorithm is now ~2x faster and provides greater precision.
 
+- `nextpow2` algorithm is now more accurate for inputs very close to a power
+of 2.  The output class now matches the input class for Matlab compatibility.
+The function no longer accepts complex inputs and will emit an error for these
+inputs.
