AnalogSource: make the Arduino AnalogSource interrupt driven
...
this fixes several problems with reading analog sources:
- we were getting poor values because we didn't wait long enough for
an analog source to settle
- we wasted a lot of CPU cycles waiting for conversions
- we were not taking averages over many samples, which we did with
the old AP_ADC driver on the APM1

TimerProcess: added suspend_timer()/resume_timer()
...
this will be used to avoid races in driver initialisation

Arduino 1.0 - changed all #includes of "WProgram.h", "wiring.h" and "WConstants.h to "Arduino.h".
...
Modified FastSerial's write function to return size_t (number of bytes written).

TimerProcess: prevent a race in setting up the timer callbacks

TimerProcess: check for duplicate registrations
...
if a driver gets initialised twice, make sure it doesn't get called
twice in the timer loop

TimerProcess: make some variables uint8_t
...
save a couple of bytes

PeriodicProcess: added set_failsafe() call
...
this adds an optional failsafe function that will be called in the
timer loop

removed AperiodicProcess code
...
this code was never being used, and was more complex than it was
worth.

timer: enable interrupts during timer processing
...
this prevents us losing serial bytes when we call sensor drivers that
take more than 100usec to read.
We also prevent timer recursion by re-enabling the timer after all
callbacks are complete

timers: change to 1kHz timer by default
...
we were using a 227Hz timer, which is far too slow

hil-sensors: added stub libraries for InertialSensor and PeriodicProcess
...
* Also added dummy ivar to APM_BMP085_hil

purple: added PeriodicProcess library
...
this library provides a clean API for drivers to request periodic
timer driven calls at whatever rate they need
