40002a58     $a3 = rtc_intr_handler
40002a5e     $a4 = 0x0
40002a60     $a2 = 0x3

0aabbea16f esp/wdt_regs.h: Add "current value" register. 
WDT is countdown timer. Current value is accessible via VAL register. At
this time it's unclear if it's RO or RW (common sense says it shoul be RO).

Source: looking at the WDT registers on a running chip.

1e9296f60c Fatal exceptions: Cleanly deal with exceptions that occur inside fatal_exception_handler_inner() 
In case of heap corruption or some other major problem, dumping details
in the exception handler can cause a crash loop - so fail out if we seem
to be going in circles.

36886412e6 Add abort() implementation 
Also reduces the IRAM footprint of the fatal exception handler, as only
the prelude (which disables interrupts & enables the flash mapping) is
in IRAM now.

Closes #54, relevant to #133.

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.
