Add cross-core int to accelerate task being awoken from another CPU.
This adds a per-CPU interrupt that can be used to poke the CPU to go do something. In this case all that is implemented is a request to yield the current task, used in case a CPU unblocks a task that runs on another CPU. This gets rid of the limitation that inter-CPU communication using queues, muxes etc can take up to a FreeRTOS tick to happen.
Specs!
Sending an in in a queue of length 1 (essentially a semaphore) as quickly as possible (just a small delay in the sender, to make sure the receiver task gets swapped out) for 10 seconds. Number indicates the amount of ints transferred
Old code:
CPU0->CPU0: 42986
CPU0->CPU1,: 2999
New code:
CPU0->CPU0: 42868
CPU0->CPU1: 62073

Feature/wdts
This adds two watchdogs to esp-idf:
- An interrupt watchdog. Kicks in if the FreeRTOS timer interupt on either the PRO_CPU or (when configured) the APP CPU isn't called for a configurable time. Panics, displaying which CPU caused the problem and the registers that may lead to the offending code.
- A task watchdog. A task has to feed it every once in a while. If not, it will print the name of the offending tasks, as well as the tasks currently running on both CPUs, and optionally panic.
Also adds a panic reason to the panic call, as well as fixes the panic code a bit.

The customers need to get information about AP that associated with ESP32 station,
these information includes RSSI, channel number etc, so add this new API
1. Modify sta to station in comments
2. Modify esp_wifi_get_ap_num to esp_wifi_scan_get_ap_num
3. Modify esp_wifi_get_ap_list to esp_wifi_scan_get_ap_records
1. Modify comments for esp_wifi_internal_tx
2. Fix delay time error in esp32_tx_flow_ctrl which is found in code review,
modify _wait_delay init value from 0 to 1
6ce01d76: rename some wifi internal APIs
aa4d2aa9: last rx buffer is reserved for mgmt frame
bb0ff4a8: tw7775 fix assert when rx auth frame before create bss
Feature/trax
Add Trax support to esp-idf. OpenOCD already has trax support, this allows an esp-idf program to also trigger this when needed. Also included: some more logic to correctly reserve memory blocks for Trax.

Some small fixes
- Kill unused uxReturn in task.c, https://github.com/espressif/esp-idf/issues/48
- Line end conversion in gpio.c
- Move heap_alloc_caps.h so components can also use it

lwip/esp32: support iperf
1. Add _exit() definition in syscalls.c
2. Fix a bug in sockets.c on which iperf depends
I'm now investigating performance of esp32, need iperf to be merged in to master branch for convience

esp32: Bootloader wake deep sleep stub
App can contain a stub program resident in RTC fast memory. Bootloader
will load the stub on initial boot. If the device wakes from deep sleep,
the stub is run immediately (before any other data is loaded, etc.)
To implement a custom wake stub, implement a function in your program:
```
void RTC_IRAM_ATTR esp_wake_deep_sleep(void)
{
esp_default_wake_deep_sleep();
// other wake logic
}
```
... and it will replace the default implementation.

We reserve 4KB Slow RTC memory to save RF calibation result and BT NVS data.
If not all these Slow RTC momory Blocks are used, we will open the other parts.

While this may reduce esp_wifi.h file readability for people who don't have a "go to definition" function in their editors, this is needed to decouple esp_wifi and esp_event headers, and possibly other headers which may use wifi types in the future.

Clean up warnings and remove unused parts of FreeRTOS
For third party components (lwip and expat), compilation flags are adjusted to silence existing warnings (i have manually checked that all warnings are benign).
In components/esp32, replaced use of WIFI_DEBUG with ESP_LOG functions.
Additionally prvLockQueue/prvUnlockQueue have been removed, dragging some other bits of FreeRTOS along.
