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
See merge request !136
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.

* master:
app_main: Return type to void
wifi: move type definitions into separate header file
wifi: use default esp_event_send handler in WIFI_INIT_CONFIG_DEFAULT
nvs: Remove flash layout arguments from nvs_init()
Add contributor agreement, update CONTRIBUTING file
Update http_request & https_request examples for new startup flow
Add very simple "hello world" & "blink" examples
Build examples out-of-tree as part of CI process
Examples: Use event groups for waiting until WiFi is associated & ESP has IP
BT example: Enable BT stack in config by default
BT: Relink component on new BT library, auto-initialise submodule if missing
Documentation: Add contributor guide, expand README & add an examples README
Update gitignore for examples
examples: Add https_request example
mbedtls: Add some initial menuconfig options
examples: HTTP request example
component/esp32: udpate wifi lib
component/esp32: modify bool argument name from enable to en
component/esp32: adjust some APIs
esptool: Bump upstream revision
* master: (32 commits)
components/nghttp: rename Makefile to component.mk
components/nghttp: add HTTP2.0 protocol feature
compoenents/esp32: don't alias start_cpu1 to start_cpu0_default
components/freertos: fix a bug with an uninitialised return value

Event handling refactoring
clean up warnings
components/esp32,bt: fix typos in comments
Startup flow refactoring
Roll back submodule version
...
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.
* master:
components/spi_flash: remove stray level of indentation
components/nvs: fix broken sentences in comment blocks
Roll back submodule version

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.
Original issue: https://github.com/espressif/esp-idf/issues/18
See merge request !111
- put contents of a few headers into c++ guard blocks
- fix off-by-one error in do_global_ctors
- remove system_init from startup code (should be called from main)
This change separates definitions in esp_event.h and functions in event.c into several parts:
- event structure definitions (esp_event.h)
- default implementations of event handlers (event_default_handlers.c)
- default implementation of event loop (event_loop.c, esp_event_loop.h)
Purpose of this change is to allow applications choose their own poison:
- full control of event loop at the expense of more bootstrap code
- pre-defined event task firing event callbacks, but less code in app_main.c
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.
Only remaining warning is in FreeRTOS queue.c, and it may be a useful one.
This change removes implicit WiFi/BT initialization from startup code.
"main" task is started once essential part of startup code is complete.
This task calls application-provided "int main(void)" function, which can call WiFi/BT init functions if necessary.
