5ffbe646e1 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.

db3a43c8ed 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.

6876ae0c3b 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.
