[Docs] Added Python is missing on the troubleshooting section

- Support Wire::end() for Slave
- Prevent Master operations when in Slave mode

Summary

New feature: Add the ability to get the peer certificate of an SSL connectio. This is useful for IoT when the root/cert trust chain has a shorter lifecylce than the device itself. Includes example code.

It adds two methods to the WiFiClientSecure client:

bool getFingerprintSHA256( uint8_t fingerprint_remote_sha256[32]) -- return true and the fingerprint (i.e. the SHA256 of the raw x509 as a DER - identical to what you see in for example your webbrowser). Or false on error.
const mbedtls_x509_crt* getPeerCertificate(); -- return the actual X509 struct or NULL on error.
Impact

No impact; backwards compatible (only adds to the API)

In this PR, we add support for M5Stack Unit CAM to CameraWebServer.

When compiling with verbose logging, the build would error with a message saying `len` is not defined in `tud_vendor_rx_cb()`. This change fixes the error.

* SD.open() new feature for creating all folders in path

This PR adds to the SD.open() function option to create all folders to the file.

SD.open(const char* path, const char* mode, const bool create)

Default value of create is false.
When true folders are created.

From issue #5019

* Update vfs_api.cpp

memccpy -> memcpy

* SD_MMC deinit fix

Wrong deinit function was called.

We don't have submodules.

* Fix build compilation due to changes in the HW_TIMER's structs

* Fix compilation warnings and errors with USB

* Update USBCDC.cpp

* Update CMakeLists.txt

* Update HWCDC.cpp

* Implement Thread-Safe I2C based on ESP-IDF API

* Update esp32-hal.h

* use proper types for size and timeout

* Allow disabling of the HAL locks

* Limit frequency settings to prevent Interrupt WDT

* File f = open() edit

added false for create

* SDMMC frequency selection based on board type

On Olimex ESP32 EVB I/O operations with SD card can cause error when LAN is used in same time.
Problem is disappearing if SD MMC frequency lower down from SDMMC_FREQ_HIGHSPEED to SDMMC_FREQ_DEFAULT.

No problem if WiFi used instead LAN.

* Code rewritten according to https://github.com/espressif/arduino-esp32/pull/5688#pullrequestreview-759359645

Return size_t instead of uint8_t from BLECharacteristic::getLength().  Allows large MTU to be used. (#5687)

Fix compilation in case NO_GLOBAL_INSTANCES || NO_GLOBAL_SERIAL is defined.

* Add an error check for empty path of an URL

* Append '/' to an URL with empty path instead of returning an error

Fixes boards.txt entries for the atmegazero_esp32s2, and also the platform.txt  --flash_size which is not letting the board compile due to its 32MB size. (#5673)

only use ksz8081 for idf versions later than 4.3 (this fixes compile as component for idf 4.3) (#5599)

esp_eth_phy_new_ksz8081 was added in IDF after version 4.3 and generates a compilation error with IDF-4.3. This change will only use esp_eth_phy_new_ksz8081 for IDF versions after 4.3
