AP_Common: PSTR def has specific version for avr-gcc 4.6 compatibility

* Also a small change in FastSerial/vprintf.cpp, which duplicates the
PSTR definition
* Won't effect others using earlier versions of avr-gcc

FastSerial: added set_blocking_writes() interface
...
this allows us to put a serial port into non-blocking mode, so that
writes that don't fit in the transmit buffer are dropped. This will be
used in flight to prevent stray printf() calls from causing large time
delays in the code

replace space() with txspace()

space() was actually intended to be tx buffer space, it just had a
bug. The name txspace() is clearer however, and should prevent
confusion as to which buffer its for

Extend the logic that preserves buffer sizing on re-begin by also avoiding freeing and re-allocating buffers when they don't change in size.
...
This can make re-opening a port faster (as the free/malloc pair can be avoided) and possibly more robust (in the case where e.g. the heap has been corrupted).

Add documentation and reformat closer to our current code standard.
...
Add support for re-opening a port without changing the baudrate or buffer sizes. By passing zero for the parameters that aren't to be changed, code can reconfigure a port without needing to know how it was originally configured.

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.

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.

Stop trying to be so clever in the tx interrupt handler. We may race with the code stuffing bytes into the ring such that we consume the last byte and empty the ring before they set the UDRE interrupt.
...
If that happens since we weren't checking the ring for emptiness we would loop and spit out the whole ring again. It's cheaper in terms of interrupt latency to just check the ring at interrupt time than it is to futz with ATOMIC_BLOCKs in the ::write code.
