Related to the issue #5773 and #2280.

_user_defined_size is removed from EEPROMClass because it is redundant in the current code
EEPROMClass::length() returns _size that is the true available size of EEPROM

The Deneyap Mini used a SerialMode custom menu item, which is not defined. The correct item, CDCOnBoot, has replaced it.

Function analogReadResolution set how many bits will analogRead return.

Find out that this functionality was added back 2017 by @me-no-dev in #161.

Summary

Modifies WiFi lib to allow dynamic buffer allocation along with SPIRAM MALLOC enabled
This gives more heap space to the users

Impact

WiFi will work the same as it was in version 1.0.6, restoring free heap.

* SPI.h add new call to return a SS pin number used.

As code example states, the SS pin needs to be explicitly set for output for SPI to work, but the pin number have to be coded in addition to the SPI logic in the library, which means this duplicates code. It is much better to just be able to get the pin number from library itself.

* Update SPI_Multiple_Buses.ino to use new pinSS method

Simplify the example case, to show usage of pinSS method. This also simplifies the example, removing duplicated code.

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.

* 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.
