Delete option to select core timer 2 as a FreeRTOS tick source
Core timer 2 is unusable for FreeRTOS ticks because it triggers a high-level interrupt. This MR deletes the option to select it.
Ref https://github.com/espressif/esp-idf/issues/234
See merge request !418
In some cases (when RTC register reads are performed from the APP CPU), a write to FRC_TIMER_INT_REG may be lost on the bus.
Writing to another DPORT register immediately before or after that works around the issue.
We write one dummy value to an address which doesn’t have any register associated with it.

1. add openssl option at menuconfig
2. remove SSL_ERR to reduce complexity
3. add more functions about debugging and assert
According these, our coders and customers may use and debug the OpenSSL code easily.
One common pattern of using assert function looks as follows:
int ret = do_foo();
assert(ret == 0); // which reads as: “do_foo should never fail here, by design”
The problem with such code is that if ‘assert’ is removed by the preprocessor in release build,
variable ret is no longer used, and the compiler issues a warning about this.
Changing assert definition in the way done here make the variable used, from language syntax perspective.
Semantically, the variable is still unused at run time (as sizeof can be evaluated at compile time), so the compiler
can optimize things away if possible.
These functions are marked as inline and are called from functions which are in IRAM.
In release (-Os) builds, the compiler may decide not to inline these functions.
Placing these functions into IRAM explicitly works around this.

vfs: implement reading from UART
This change adds support for reading from the UART FIFO via the `stdin`.
Useful for simple cases when handling lots of data is not a requirement (e.g. command prompts operated by humans).
`\r\n` -> `\n` conversion is guided by the existing `CONFIG_NEWLIB_STDOUT_ADDCR` configuration option.

fixes for github issues
This MR includes commits from several Github PRs, as well some fixes for issues reported on Github and on the forum.
- compile PHY-related code only when WiFi is enabled
- fix macOS setup instructions
- fix some of the Sphinx warnings
- update docs index, improve structure of the readme-
- wifi: fix typos, rename ESP_ERR_WIFI_NOT_START to ESP_ERR_WIFI_NOT_STARTED
- sdmmc: fix explanation of flash voltage regulator configuration efuses
- sdmmc: change idx num of example
- fix i2c_get_period name
- fix esp_log_level_set function name in docs
See merge request !420
If using WIFI_INIT_CONFIG_DEFAULT, error message will point out lack
of WiFi. Otherwise linker errors on WiFi symbols should help give a
clue as to what is broken.

Fix panic register dump format
Fix misplaced a printf somewhere causing an enter to be printed after every register in the panic regdump instead of every 4th register.

Toolchain detection: Allow for Windows executable name and not-yet-configured toolchain path
Windows executable name based on fix suggested by @krzysztof
See merge request !416
Most of the packages mentioned are only needed for building the toolchain using crosstool-NG, not for the normal ESP-IDF environment.
Mention that pyserial needs to be installed (fixes https://github.com/espressif/esp-idf/issues/229).
