DrZiplok 4d6637389a Add a method to BetterStream and FastSerial that can be used to report 
the amount of data that can be written without blocking.

tridge60@gmail.com 211de598c3 implemented typesafe PSTR() 
This makes PSTR() type safe by using a 1 byte wrapper
structure. Attempts to use the wrong varient of a print function will
generate a compilation error.

DrZiplok@gmail.com f30bf9cab7 Add format attributes to printf and printf_P. The latter is a bit wishful as gcc isn't smart enough to deal with what PSTR does, but with some other hackery this can be used to generate useful warnings. 
Add a workaround for a GCC bug that generates spurious warnings when PSTR() is used.

DrZiplok@gmail.com 43262a573f Bring in floating point support for BetterStream::printf, courtesy of the avr-libc implementation. 
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.

DrZiplok@gmail.com 271d4736a8 Factor the Stream-related enhancements out from FastSerial proper, so that we could use them on other Stream subclasses if that seemed worthwhile. 
Add print_P and println_P implementations to give folks wedded to the vanilla Stream methods a way to print PROGMEM strings.
