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

- spaces->tabs in tasks.c
- update vfs_uart.c to use per-UART locks
- add license to vfs_uart.c
- allocate separate streams for stdout, stdin, stderr, so that they can be independently reassigned
- fix build system test failure
- use posix off_t instead of newlib internal _off_t

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.
