Strip the stdio integration from FastSerial as we aren't using it and it just wastes space. Note that this does not attempt to fix the bogus floating point handling in ::print(ln). That's an issue for another day. BetterStream::printf(_P) aka FastSerial::printf(_P) support is now as documented for avr-libc printf with floating point support enabled. git-svn-id: https://arducopter.googlecode.com/svn/trunk@895 f9c3cf11-9bcb-44bc-f272-b75c42450872
