8405b989f9 iomux_set_function: remove the IOMUX_FUNC transform of the func argument.
The allows the IOMUX_GPIO<n>_FUNC_<function> definitions to be used here.

678b59babf Honour values of configCPU_CLOCK_HZ & configTICK_RATE_HZ for tick rate
Fixes #147

* Can vary tick rate from 100Hz via configTICK_RATE_HZ. Note that the
  SDK binary libraries are hard-coded to assume the tick rate is 100Hz,
  so changing the tick rate may have unexpected consequences for lower
  layer WiFi behaviour (such as certain kinds of timeouts happening
  faster/slower.)

* Setting configCPU_CLOCK_HZ to 160MHz means ESP will set 160MHz during
  initialisation. Only 80MHz and 160MHz are supported.

* Timing of tasks is no longer affected by current CPU freq (whether set
  via configCPU_CLOCK_HZ or via sdk_system_update_cpu_freq().)
  Previously doubling the CPU frequency would double the tick rate.

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.

640609c3f5 lwip sys_arch: Add functional xInsideISR implementation
Relies on global flags set when the user ISR is executing.

Unclear if this fixes any bugs as ISR code may not have been calling
into LWIP, but the previous implementation was broken.

fee987d5cf Startup code: Move user_start_phase2 to irom section
This saves 1020 bytes from the text (IRAM) section by preventing
inlining of user_start_phase2() (and dump_flash_config_sectors() as
well) into the IRAM function sdk_user_start().
