Test Programs:

Put in Release Notes: No

Module(s): scantable class

Description:

Enabled a row selection in scantable.flag.

• A parameter 'row' is added to scantable.flag. The default value -1 applies

specified channel flags to the all rows in the scantable (same as previous code).

• A parameter 'whichrow' is also added to ScantableWrapper::flag and

Scantable::flag accordingly.

• The actual flagg application part in the code Scantable::flag is moved to a new

private function Scantable::applyChanFlag(uInt whichrow, vector<bool> msk, uChar flagval).
The function applies flag with a value, 'flagval', to masked channels, 'msk',
in a selected row, 'whichrow'.
