* 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
workaround for #5043. There is a timing issue with HardwareSerial::end. I'm not sure what is hung, but it should be possible to see this in jtag, as it does cause a reboot if you let it. The delay needs to be before you detach the device!?
This is very much still work in progress and much more will change before the final 2.0.0
Some APIs have changed. New libraries have been added. LittleFS included.

Fixed use of CONFIG_BLUEDROID_ENABLED instead of CONFIG_BT_ENABLED in HAL. This prevented compilation with Nimble-only configuration without apparent benefit.
Added guarded define to set the stacksize on the main looptask.
Advantage of this is that build_flags can be used to provide a different value for the stack size should it be neccessary
default behaviour is unaffected

* Corrections of Find, FindUntil and FindMulti
Find has some bug that is not working with Ethernet.find() so, I copied code from Stream.h and Stream.cpp in AVR-CORE library and now it's working perfectly.
I don't know where was the error, but an Ethernet.find compiled to MEGA2560 was working but not working when compiled to esp32, after corrections of code (copy of AVR-Core libraries) it's working perfect.
So probably has some error on original ESP32-Core library.
Below is part of code that was working with MEGA2560 and not with ESP32 libraries.
client.find never return TRUE with ESP32 original library and with AVR it's works.
boolean esp32_fw_update(EthernetClient &client, DecodedHeader &header, const String &field_filename, const String &field_crc) {
char bound[header.boundary.length()+3];
char term[]="\r\n";
strcpy(bound,header.boundary.c_str());
strcat(bound,term);
while (client.find(bound)) {
String line=client.readStringUntil('\r');

* Add an aditional (void *) arg to the RMT callback - to allow more flexible handling of the callback (e.g. by passing a private struct or a class pointer). Same pattern as used by the Ticker() and many others. Example updated & new example with a trapoline added.
* Fix example for new API
* Fix lint warnings
* Add a second missed example.
* Correct timeout & improve socket error handling.
Fixes crash on ESP32 when I2C FiFo overflows and interrupt function is unable to handle crash and throws this error:
[E][esp32-hal-i2c.c:1013] i2c_isr_handler_default(): unknown int=4

Background
The current implementation of Update() uses the spi_flash_* api to write and read from flash. These functions ignore the partition->encrypted flag and always write raw data to flash even if the partition is marked as encrypted.
Changes in this PR
Update() now uses the esp_partition_* api.
Wrapper functions for esp_partition_* added to ESP.cpp. This was done to maintain a consistent approach to the way the spi_flash_* functions were used. I note though that not all of the esp-idf functions are used are wrapped, for example esp_ota_get_next_update_partition() so it may be that these should not be added?
The current implementation of Update() changes the first (magic) byte of firmware to 0xFF on write, and then when the firmware is completely written changes it back to ESP_IMAGE_HEADER_MAGIC. This works without erasing the sector because flash bits can be changed from 1->0 (but not 0->1). If the flash is encrypted then the actual data written to flash will not be all ones, so this approach will not work. In addition, encrypted flash must be written in 16 byte blocks. So, instead of changing the first byte the changed code stashes the first 16 bytes, and starts writing at the 17th byte, leaving the first 16 bytes as 0xFF. Then, in _enablePartition() the stashed bytes can be successfully written.
Benefits
Whilst it's not possible to use encrypted flash directly from either the Arduino IDE or PIO it's reasonably straightforward to compile and flash a bootloader with the necessary support from a simple esp-idf project and then use ArduinoOTA for subsequent updates. This PR enables the use of this workflow until such time as encrypted flash is supported, and is a first (small) step toward adding support.
Regardless of the above, the esp_partition_* api is recommended over the api_flash_* api.
Application code should mostly use these esp_partition_* API functions instead of lower level spi_flash_* API functions. Partition table API functions do bounds checking and calculate correct offsets in flash, based on data stored in a partition table.
