bfd38cd1e2 Experimental support for storing const strings in SPI flash or IRAM
As discussed in #11

Known limitations:
- Only supports l8ui/l16ui
- Unoptimised load routine
- Not called from DoubleExceptionHandler but should be
- Doesn't restore state properly when falling through to fatal exception handler

147257efa4 Almost functional OTA support
ota_basic example can receive new image via TCP.

However - writing to flash with interrupts disabled causes data loss,
and the TCP flow is very slow to recover. Linux sender quickly ramps up
RTT timer to very long retry intervals, crippling performance &
throughput.

Running the update without the flash writes causes the data to be
received quickly, so this is definitely an issue with the time taken for
the erase cycle.

Progress towards #10

1b0124cf05 Timer FRC1 & FRC2 registers
Mostly determined from reverse engineering and poking around.

Includes first "experiments" program with random bits and pieces for
poking at registers, may be useful to keep in source control but not
useful for writing actual programs.

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
