For usb_serial_jtag REPL only, xTaskCreate was passing a pointer to
esp_console_repl_com_t, while esp_console_repl_task was expecting
a pointer to esp_console_repl_universal_t.
The way the two structures are defined, this makes no difference, and
the pointer values are the same. Still, this could potentially break
in the future.
(I am not sure what is the distinction between repl_com (common?) and
repl_universal; it seems that `int uart_channel` could just as well
be part of esp_console_repl_com_t; alternatively, as suggested in the
previous commit, this structure could contain a callback function
pointer, which would allow `esp_console_new_repl_*` functions to
specify how stdin/stdout should be initialized by the REPL task.)
The crash occurred when calling setvbuf(stdin,...) with stdin==NULL.
This happened because esp_console_repl_task started running before
its args->uart_channel was initialized; then esp_console_repl_task
went into the code path 'uart_channel != CONFIG_ESP_CONSOLE_UART_NUM',
and tried to 'fopen("/dev/uart/0");`
Since the UART VFS is not registered when ESP_CONSOLE_USB_SERIAL_JTAG
option is enabled, fopen failed and 'stdin' was NULL.
Fix by moving the initialization of repl task arguments before the
start of the task, same as it is done for the usb_cdcacm case.
The crash started happening after the commit 287ab7566b. I haven’t
verified this, but I guess the reason why it wasn’t happening before
was that xTaskCreate was not correctly yielding to the newly created
higher-priority 'repl' task, therefore the code which was setting
the repl task arguments after xTaskCreate had time to execute.
It should be noted that the 'uart_channel' argument is a bit hacky,
in the first place. The code should be refactored to pass a callback
function to the repl task, and let this callback initialize stdin and
stdout based on the chosen console channel. Then esp_console_repl_task
does not require assumptions about the specific interface used.

Console sets UART clock source to REF_TICK on ESP32 and ESP32S2 by
default, however, APB clock frequency does not change when power
management is disabled. Using APB clock source allows higher baud rates
for UART console.

Previously linenoiseProbe would accept any 4 byte response, even one
that isn't expected. This adds a check that the first byte of the
response is ESC.
Suggested in https://github.com/espressif/esp-idf/issues/8839.
This commit updates the chip independent system chapters of the
programming guide for esp32s3.

Console example doesn't duplicate code in `console` component.
Linenoise has been improved: it now has a parametrized command line
length. It is now possible to paste data efficiently to the console.
Note: this can only be done if the cursor is at the end of the line.

Fixes a regression from 753a92952: if cb was negative, read_bytes
overflowed, because the type was changed from int to size_t.
Also fixes incorrect timeout calculation: timeout_ms was 200, but
each iteration delayed for 10ms, and reduced timeout_ms by 1. This
made the effective timeout to be 2000ms.
* changing dependencies from unity->cmock
* added component.mk and Makefile.projbuild
* ignore test dir in gen_esp_err_to_name.py
* added some brief introduction of CMock in IDF
Calloc function tries to allocate 4096 bytes.
If such memory is not available, it returns NULL pointer.
This exception was not handled in the code, causing a dirty crash.
