1728ef3dfc Flush the uart tx fifo before a restart. (#274) 
Also comment the point at which the bus clock that drives the uart changes on startup and comment out the change in the uart divisor. This at least allows a consistent uart baud rate during a restart if using the rate 115200.

4c78db81d8 sysparams: get/set int32 and int8 apis. (#209) 
Rename the get/set_int api functions to get/set_int32.

Add get/set_int8 api functions too in anticipation of more efficient implementations for these.

678b59babf Honour values of configCPU_CLOCK_HZ & configTICK_RATE_HZ for tick rate 
Fixes #147

* Can vary tick rate from 100Hz via configTICK_RATE_HZ. Note that the
  SDK binary libraries are hard-coded to assume the tick rate is 100Hz,
  so changing the tick rate may have unexpected consequences for lower
  layer WiFi behaviour (such as certain kinds of timeouts happening
  faster/slower.)

* Setting configCPU_CLOCK_HZ to 160MHz means ESP will set 160MHz during
  initialisation. Only 80MHz and 160MHz are supported.

* Timing of tasks is no longer affected by current CPU freq (whether set
  via configCPU_CLOCK_HZ or via sdk_system_update_cpu_freq().)
  Previously doubling the CPU frequency would double the tick rate.

697d5b72bc NMIExceptionHandler: Don't save callee-saved registers, fix stack alignment 
NMI routine sdk_wDev_ProcessFiq seems to be written in C, meets ABI
calling conventions for callee-saved registers. Not sure why SDK
handlers saved them.

NMI handler now also meets the ABI requirement that stack is 16 byte
aligned (doesn't seem strictly necessary, but can't hurt.)

89c481c606 Simplify interrupt and RTOS timer tick handlers 
RTOS Timer tick handler is now the same as any other ISR.

This causes a few subtle behaviour changes that seem OK but are worth noting:

* RTOS tick handler sdk__xt_timer_int() is now called from one stack
  frame deeper (inside _xt_isr_handler()), whereas before it was called
  from the level above in UserHandleInterrupt. I can't see any way that
  the extra ~40 bytes of stack use here hurt, though.

* sdk__xt_timer_int() was previous called after all other interrupts
  flagged in the handler, now it's called before the TIMER FRC1 & FRC2
  handlers. The tick handler doesn't appear to do anything particularly
  timing intensive, though.

* GPIO interrupt (value 3) is now lower priority than the SPI
  interrupt (value 2), whereas before it would have been called before
  SPI if both interrupts triggered at once.
