Earle F. Philhower, III f762721603 Use sprintf to output floats in Print/dtostrf ...

Fixes #7043

Two slightly different custom routines were implemented by hand in
dtostrf (an AVR-lib non-ISO function) and Print.  This resulted in
inconsistent output of float/double vars when rounding was needed.

Replace them all with a call to sprintf(), removing the duplicated, not
quite correct code.

Print(String(float)) and Print(float) now generate the same output.
