…use with RS485 auto RTS (#7935)

* Added setMode function to set the esp32 uart mode

Used to set the esp32 uart mode for use with RS485 Half Duplex and the auto RTS pin mode. This will set/clear the RTS pin output to control the RE/DE pin on most RS485 chips.

* Add v2.0.7 in issue template (#7871)

* Fix the F_CPU frequency for the ESP32-S3

Hello, I was using the FastLED library and it was complaining about F_CPU not being defined. So, I just noticed that it is not defined for the ESP32-S3 module. So I made this change in the header file and it compiled. Therefore I wanted to propose this change to the HAL library to improve compatibility. Thank you for your time.

* Makes F_CPU generic based on the SoC frequency

Works for ESP32, ESP32C3, ESP32S2, ESP32S3

* Includes ESP32C3 in the F_CPU definition

Necessary for ESP32 Arduino Core 2.0.x based on IDF 4.4

Fixed library crash on low memory where `new char[1460];` throws an exception.  `malloc` is a safe drop in replacement.

Revert to previous definition of `FPSTR` and `F` macros.

* USB: enable DFU interface and stub

* nano_nora: add Arduino Nano ESP32 board support

* [pin_remap 1/3] platform: define ARDUINO_CORE_BUILD when building core files

* [pin_remap 2/3] core,libs: add pin remap hooks

* [pin_remap 3/3] nano_nora: implement and enable pin remap

* nano_nora: fix: reset all matrix connections at boot

* nano_nora: add recovery image for release/v2.x

* nano_nora: use official Arduino branding

* nano_nora: core split + recovery mode rework

Use an absolute address in SPIRAM to store the magic tokens, almost at the
end of the memory, to avoid the markers from being overwritten on any kind
of sketch and core combination.

Also, only start the recovery once if a valid binary is present in the
Flash, by immediately setting that for the next boot when recovery
starts.

* platform: fix: use {compiler.sdk.path} for sdk path

In preparation for the sdk -> tool transition

* package_index: remove dfu-util from template

The tool is already available in mainline package_index.json

* on_release: allow single board packages

* io_pin_remap: fix tone() function mapping declaration

Since tone() can have either 2 or 3 parameters, pass any argument after the
first to the actual function implementation.

* io_pin_remap: add sanity checks to the core build

Building with BOARD_HAS_PIN_REMAP but without setting ARDUINO_CORE_BUILD
on core files is absolutely forbidden, as this would lead to multiple
pin remappings being silently applied on the same numbers.

Also advise the user when, on a board that has a custom pin mapping,
- the core is being built without pin mapping support, or
- the user explictly asked to use GPIO pin numbers.

"touch" would create the file if not present, but not delete its

* platform: make debug_custom.json file customizable by board

* platform: fix default debug prefix

"debug.toolchain.prefix" must end with a dash, since only the tool name is
appended to this string.

The reason this is not a major issue is that the "debug_custom.json" file
(copied in the sketch directory when debugging is enabled) forces its own
prefix. And to make things more interesting, the "toolchainPrefix" entry
in that file should _not_ end with a dash.
