732b175c29 Bug #20569 Garbage in DECIMAL results from some mathematical functions 
Adding decimal "digits" in multiplication resulted in signed overflow and
producing wrong results.

  Fixed by using large enough buffers and intermediary result types :
dec2 (currently longlong) to hold result of adding decimal "digits" 
(currently int32).

4858032176 Fix for bug#17602 Server crash on AVG/SUM over DECIMAL column(2nd ver) 
The table may be corrupted and decimal columns may have invalid values in this case.
To prevent crash we need to check that decimal column has allowable value.
In case of invalid value generate warning and set the value to 0.
