## Impact
This PR fixes issue #5493 by reverting the removal of necessary code as described above.

Thanks @chegewara

I2C Scan was failing because i2c_master_write does not accept size of 0. This change checks and skips that call if no length is provided (usually when scanning)

Can still race if Serial.begin() is not called in setup()

Fixes: https://github.com/espressif/arduino-esp32/issues/5503

* Add initial support for USB MSC

* Add Firmware Upload/Download With MSC

Current running firmware is available as file inside the MSC Disk. To update the firmware on the ESP, just copy a regular firmware bin into the drive

* Support overwriting of the firmware file

Overwriting a file is done totally differently on MacOS, Windows and Linux. This change supports it on all of them.

* Allow CDC, FirmwareMSC and DFU to be enabled on boot

* Add example ESP32-S2 USB-ONLY board

* Various device code optimizations

Added `end()` methods to MSC classes
Made begin() methods safe to be called multiple times
Optimized CDC class

* Fix CDC Connect/Disconnect detection in Arduino IDE on Windows

* Rework cdc_write

* Update ESP32-S2 board configs

Fixes: https://github.com/espressif/arduino-esp32/issues/5488

Fixes: #5375
Fixes: #5050

lwip lib bundled with esp32 Arduino supports only one ntp server. Any additional servers set are just silently ignored.
This default is different from esp8266 Arduino core and very confusing. Most of the examples provided uses 3 different ntp servers for redundancy while only the first one is used actually.
Addressing issue #4964

Fixes: #5429

- Device will not reset if previous baudrate was not 9600
- CDC Device is not recognized if WebUSB is enabled

* Fix compile archive arguments for the new toolchain

* Add menu to S2 for picking through which port to upload

Internal USB CDC requires to reset and wait for the new port (because persistence is not yet stable)

* USB CDC should also be started in main

* Fix URL and USB version for WebUSB

* Update vendor callback API

* Update CDC::write to use TX_DONE semaphore

* Update USB_Serial example

* Update toolchain

* Update package_esp32_index.template.json

* add optional component dependencies after Kconfig options are known (#5404)

Until this commit, Kconfig options (e.g. CONFIG_TINYUSB_ENABLED) were
used in conditions preceding idf_component_register to determine which
components need to be added to `arduino` component requirements.
However the Kconfig options aren't known at the early expansion stage,
when the component CMakeLists.txt files are expanded the first time
and requirements are evaluated. So all the conditions evaluated as if
the options were not set.
This commit changes the logic to only add these components as
dependencies when the Kconfig options are known. Dependencies become
"weak", which means that if one of the components isn't included into
the build for some reason, it is not added as a dependency.
This may happen, for example, if the component is not present in the
`components` directory or is excluded by setting `COMPONENTS` variable
in the project CMakeLists.txt file.
This also ensures that if the component is not present, it will not be
added as a dependency, and this will allow the build to proceed.

* Make String::concat() faster for some types.

This patch removes the unneeded call to `strlen()` when concatenating some types to a `String`. Additionally it fixes some whitespace for consistency.

* Update WString.cpp

original PR #5278 from @s-hadinger, which is not accepted because of failure of CLAassistant

`ESP.getFlashChipSize()` always returns `0` on Esp32c3 due to a change in the Flash layout. It looks like to Espressif documentation was not updated accordingly.

https://docs.espressif.com/projects/esp-idf/en/latest/esp32c3/api-reference/storage/spi_flash.html#spi-flash-size

- Esp32 and Esp32s3 have the flash information update by esptool.py
and decribed here
- https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/storage/spi_flash.html
Esp32c3 has no image information at 0x0000 and contrary to the docu
this information is at offset 0x0000

Fixes #4866

WMath.cpp doesn't include Arduino.h, where makeWord(h, l) is declared, common denominator type therefore is uint8_t, which is in use already in Arduino.h, too. (#5230)

This PR lets the user override the LOOP STACK SIZE set in sdkconfig (for example with -DARDUINO_LOOP_STACK_SIZE=12288).

In esp32-hal-log, direct calls to ESP_LOG_x macros is more efficient than using intermediate function log_to_esp (#5081)

As indicated in https://github.com/espressif/arduino-esp32/issues/4845#issuecomment-820540642_ it is more efficient to call directly the ESP LOG macros. This spares a function call, a 512b buffer and a call to vsnprintf. No change in functionality.
