Fix #84 operation at 1200 baud.

Fix #83 for data widths other than 8 bits.

Fix #82 to make flush semantics match AVR.

…_Datasheet–09/2015,

constant in formula should be 65536, not 65535.  Also add 0.5 to round correctly to closest integer.

@TomKeddie thanks for submitting! The changes look good.

I've proposed #86 as an alternative to TomKeddie@103ddee. It changes UART configuration to use asynchronous fractional mode.

@sandeepmistry I think #86 is better. Having floating point code in the base libraries should be avoided wherever possible. You should commit and then I will pull and clean up my change.
