Improve matcopy interface
...
* rows = 0 or cols = 0 is now a legal input and
takes quick return path
* Follow BLAS/LAPACK convention that the leading
dimensions must be at least 1.

Simplify rotg
...
* The check da != ZERO is no longer necessary since there
is a special case ada == ZERO, where ada = |da|.
* Add the missing check c != ZERO before the division.
Note that with these two changes the long double code
follows the float/double version of the code.

Fix division by zero in zrotg
...
The cases
[ c s ] * [ 0 ] = [ |db_i| ]
[-s c ] [ i*db_i ] [ 0 ]
and
[ c s ] * [ 0 ] = [ |db_r| ]
[-s c ] [ db_r ] [ 0 ]
computed s incorrectly. To flip the entries of vector,
s should be conjg(db)/|db| and not conjg(db) / da,
where da == 0.0.
