Fixes for github issues
This MR contains a bunch of small fixes for issues raised on Github and esp32.com forum:
- vfs doesn't check error code returned by open syscall
- spi_flash doesn't work when built in release mode
- duplicate definition of O_NONBLOCK when combining LwIP socket.h with sys/fcntl.h
- wrong order of creation of standard streams
- `_times_r` returning incorrect values, causing `clock`to return double of the actual time
- driver/gpio.h: comment fix
- wifi event handlers: fix incorrect MAC address printed by logging statements
- move some functions out of IRAM when compiling for bootloader
Please check commit descriptions for links to issues/forum posts and more details.

newlib: fix compilation error when no timers are enabled in menuconfig
I have checked that three options (RTC/RTC+FRC1/FRC1) work, but didn't check "None" option.
This adds some missing ifdef blocks to remove "unused function/variable" warnings and fixes the use of `__errno_r` in a non-reentrant function.
See merge request !174
LwIP will define O_NONBLOCK in sockets.h if it isn't defined yet.
If sys/fcntl.h is included after socket.h, there will be duplicate definition.
Work around by including sys/fcntl.h into lwipopts.h.

esp32/make: add detailed return error code for wifi APIs
1. Add detailed return error code for wifi APIs
2. Add description about error code in esp_wifi.h
3. Modify esp_wifi_reg_rxcb to esp_wifi_internal_reg_rxcb
4. Modify esp_wifi_set_sta_ip to esp_wifi_internal_set_sta_ip
5. Mark system_init as deprecated API

wpa_supplicant: replace pre-built crypto library with source code
This change replaces libcrypto.a pre-built library with source code from wpa_supplicant.
For now i've decided to keep the modified layout of source and header files which is used in the esp32_rtos_sdk_core project. This will make it easier to move other parts of wpa_supplicant from esp32_rtos_sdk_core into esp-idf. Once we move everything, we can rearrange the files and upgrade wpa_supplicant to latest version.

implement time syscalls
This change adds optional support for libc time functions.
New menuconfig option allows selecting FRC1, RTC, both, or none to be used for timekeeping.
- If only FRC1 timer is used, gettimeofday will provide time at
microsecond resolution. Time will not be preserved when going
into deep sleep mode.
- If both FRC1 and RTC timers are used, timekeeping will
continue in deep sleep. Time will be reported at 1 microsecond
resolution.
- If only RTC timer is used, timekeeping will continue in
deep sleep, but time will be measured at 6.(6) microsecond
resolution. Also the gettimeofday function itself may take
longer to run.
- If no timers are used, gettimeofday function will return -1 and
set errno to ENOSYS.
`times` function returns time derived from FreeRTOS ticks. It reports all as 'system' time, 'user' time is reported as zero.
`settimeofday` function may be used to set current time.
LwIP SNTP module is hooked up into the system through `settimeofday`/`gettimeofday`.
Example demonstrating this functionality is also added.

Deep sleep: Any source named rtc_wake_stub* is linked as RTC wake stub code
Also move esp_deepsleep.h documentation out to docs/deep-sleep-stub.rst

Fix spi_flash_write regression and nvs error recovery
In the previous set of changes related to spi_flash, new alignment checks were added. One of these checks, word alignment of `src` buffer in `nvs_flas_write`, was unnecessary. ROM `SPIWrite` function can handle unaligned source buffers.
This change caused an error to be returned to nvs for some legitimate write operations. Due to a bug in nvs, further write operations were possible, while the internal state of `Page` instance was broken. In WiFi functional tests, this inflicted havoc on the nvs partition, creating multiple duplicate items in the affected page. Because multiple duplicate items per page were never supposed to be handled during page load, duplicates were not removed. Thankfully this caused an assert at a later point in the loading process, otherwise this bug would be very difficult to detect.
This change set fixes the original spi_flash regression, handling of `INVALID` state of `nvs::Page`, and handling of duplicate items.

Feature/tw8155 optimize tx flow control
1. Remove TX flow control in LWIP
2. Make the return value of esp_wifi_internal_tx consistent with LWIP error code
See merge request !164
146f5962 - Make the return value of esp_wifi_internal_tx consistent with LWIP error code so that
the up-layer can detect the out-of-memory error and take action accordingly, such do flow control.
