[issue4707] round(25, 1) should return an integer, not a float

[Mark Dickinson]

Some minor modifications to the last patch:

 - fix round docstring:  it now reads "round(number[, ndigits]) -> number"
   instead of "round(number[, ndigits]) -> floating-point number"
 - add Misc/NEWS entry
 - add extra tests for round(x, n) with n huge and positive
