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:

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

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...)

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.

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.

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
