b61b62136b gcc __attribute__((constructor)): Remove hacked calling, move ctor sections to flash 
More hacky moving of parts of .rodata to flash, until we can move all of
it.

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.

424dc0f3b0 Add C++ support to Makefile, and proof-of-concept simple.cpp example 
This is a work in progress based on @mikejac's work.

Missing:
* No 'new' operator.
* I don't think STL is currently supported.

efc454035c Move all code paths touched by NMI to IRAM 
Prerequisite for calling Cache_Read_Disable() for OTA updates.

Massive thanks due to @foogod and their xtobjdis tool, creating the call
graph of where the wDev_ProcessFiq touched (including in newlib, etc.)
would have otherwise been very painful:

ed7ba52c9a Add exception vectors & low-level handlers 
At the moment these are almost bit-for-bit copies of the vector
behaviour in the RTOS SDK, but hopefully that will start to change.

Progress towards #2

49268a33e1 Link against newlib from esp-open-sdk's libcirom, replace FreeRTOS heap management. 
Compiles and runs, expects xtensa lock.c patch in newlib (will still run
otherwise but malloc/free and other functions will be non-memory-safe...)

0dbb6d31a5 Add IRAM attribute for IRAM loaded symbols, add to common FreeRTOS functions 
Closes #7.

It'd be nice to change the linker script so .text is always linked to
IROM instead of needing to objcopy each compiled file. The sticking
point for this is libgcc & libhal, which have symbols in .text that need
to be loaded to IRAM.

81afe58334 Change symbol extraction to use objdump not nm 
nm outputs warnings to stderr so hard to clean output.

Also now picks up global variables, like NMIIrqOn.

e743d03a78 Preprocess all binary SDK symbols to add an sdk_ prefix 
* This fixes the problem of axTLS symbols hmac_md5/hmac_sha1 having same
  name as symbols in libwpa (which have incompatible signatures)

* Also allows for easier identification and piece-by-piece removal of
  binary functions.

* Some libc symbols are not renamed, list is in lib/symbols_norename.txt
