> Refactor AbstractStringBuilder to maintain consistency among count, coder, 
> and value buffers while the buffer capacity is being expanded and/or inflated 
> from Latin1 to UTF16 representations. 
> The refactoring pattern is to read and write AbstractStringBuilder fields 
> once using locals for all intermediate values. 
> Support methods are static, designed to pass all values as arguments and 
> return a value.
> 
> The value byte array is reallocated under 3 conditions:
> - Increasing the capacity with the same encoder
> - Increasing the capacity and inflation to change the coder from LATIN1 to 
> UTF16
> - Inflation with the same capacity
> 
> Added StressSBTest to exercise public instance methods of StringBuilder.
