f146a3c0cd Add in-progress RTC register header (some registers still undocumented) 
Author for this work is @foogod, extracted from 1da996e (open-libmain branch).

Progress towards #8.

23ea182e83 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.

77813c8032 Rename GPIO_CONF_PUSH_PULL to GPIO_CONF_OPEN_DRAIN 
Seems I got the functionality of this bit inverted when
initially testing.

In testing it also seems open drain mode is ignored on some pins, which
still source current. Needs more investigation though (may be pullups
internal to the ESP modules or set by default in software.)

Relates to #45
