 Use the shortest representation when printing doubles

 - Use the shortest representation (enough to guarantee roundtrip).
 - Uses scientific notation for absolute numbers smaller than 1e-8. The
 previous behaviour was to output 0 for absolute values smaller than 1e-12
 and fixed notation for anything bigger than that.
 - Uses scientific notation for absolute numbers greater than 1e+15 (same
 behaviour).
 - The precision parameter now also affects the scientific notation (before
 it was fixed [5-8]).
 - All output functions now respect the requested precision (without any
 limits).
 - The default precision is the same (9 for GeoJSON, 15 for everything
 else).

 Many regress test changed mainly because of the fixes to the precision
 parameter, which is now respected as the amount of digits after the fixed
 point.
