BLE data has no '\0' terminator, therefore it can't be printed as a regular C string.

This change will allow specifying connect timeouts below 1 second. Without this change, if connect timeouts under 1 second are given, the connect defaults to 0ms and fails.
This will also allow timeouts in fractions of seconds, e.g. 1500ms. Without this change, connect timeouts are truncated to full second increments.
* Make parameter timeout_ms clear
* Change connection timeout_ms name for clarity

* setPins fix ESP32 "specified pins are not supported by this chip." (#7646)
[ESP32: SDMMCFS::begin hardcodes the usage of slot 1, only check if the pins match slot 1 pins.]
setPins() was testing pins D1, D2 and D3 all against D1 ... fine in 1 pin mode when all are -1 not so much if you're trying to get 4 pin mode working.
I now see this function doesn't really do anything on the ESP32...accept now correctly checks that you are trying to use the slot 1 pins.

* Reword "ESP-IDF as Component" (#7812)
I think "Arduino as an ESP-IDF component" or just "As ESP-IDF component" instead of "ESP-IDF as Component" is more correct way to name the link.
1. "ESP-IDF as Component" would imply that ESP-IDF is some sort of library for Arduino, which is (IMO) misleading, because it's true the other way around.
2. It's written as "Arduino as an ESP-IDF component" on the webpage it points to as well.
- Also I removed the capitalization from "Component" as I have not found a reason why is it capitalized.

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)
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.

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
Co-authored-by: 0xDEADBEEF <0xde4dbeef@gmail.com>
The i2c peripheral will hang if a READ request is issued with a zero data length. The peripheral
drops into a continuous timeout interrupt response. The STOP command can not be set out to the I2C
bus. The SLAVE device correctly ACK'd the address byte, with READ bit set, it has control of the SDA
pin. The ESP32 send out the next SCL HIGH pulse but, since the SLAVE is in READ Mode, and the First
bit it is sending happened to be a ZERO, the ESP32 cannot send the STOP. When it releases SDA during
the SCL HIGH, the pin does not change state. The pin stays low because the SLAVE is outputing a LOW!
The ESP32 drops into a perminent WAIT state waiting for SDA to go HIGH (the STOP).

#1869 exposed a resource exhaustion issue. The current HAL layer for I2C support is designed to use a shared interrupt, But, during debugging to solve the interrupt overloading condition identified in #1588, and the generation of pr #1717, the interrupt allocation parameters were changed. This change was unnecessary, the code will work successfully with shared interrupts. So, there is no need to assign a private interrupt for each I2C peripheral.
If the esp32 is reset during a i2c read cycle the slave device may be in control of the SDA line.
If the SDA line is held low, the esp32 cannot issue a START or STOP to recover the bus.
The previous code did not correctly configure the SCL output pin, and it cycled SCL 9 times with SDA Low. Since the slave device was in a READ cycle, it just continued outputting the bits of the current byte. When the ACK/NAK bit space occurred, The low output value of SDA was interpreted as ACK so the slave device continued with the next byte. It never terminated the READ cycle.
This new code will correctly recover from an interrupted READ
* ReSTART fix, Sequencing fix
pr #1665 introduce a problem with ReSTART, when solving this problem I found an interaction between the TxFifo refill, RxFifo empty and CMD[] fill. during certain sequences a dataqueue command would be skipped, this skipping resulted in a mismatch between the contents of the TxFifo and the i2c command sequence. The problem manifested as an ACK error.
In addition to this required bug fix I propose:
* `Wire.begin()` be changed from a `void` to a `bool` this will allow the reset functionality of `Wire.begin()` to be reported. Currently `Wire.begin()` attempts to reset the i2c Peripheral, but cannot report success/failure.
* `Wire.busy()` be added. this `bool` function returns the hardware status of the bus. This status can be use in multi-master environments for application level interleaving of commands, also in single master environment, it can be used to detect a 'hung' bus. With the functional change to `Wire.begin()` this allows app level recover of a hung bus.
* `Wire.lastError()` value updated for all errors, previously when interleaving `Wire.endTransmission(false)` and `Wire.readTransmission(false)`, the 128 byte `Wire.write()` buffer was exhausted without generating and error(very exotic). I discovered this error when I created a sequence of directed reads to a EEPROM. Each directed read used 2 bytes of the 128 byte `write()` buffer, so after 64 consecutive ReSTART writes with ReSTART reads, `Wire()` had no room to record the directed address bytes. It generated just a NAK check without setting the EEPROMs internal register address. The succeeding ReSTART read succeeded at incorrect address.
* Changes to the HAL layer:
** added `i2cGetStatus()` which returns the i2c peripheral status word, used to detect bus_busy currently
** added `i2cDebug()` programmatic control of debug buffer output
** changed `i2cAddQueue()` to allow data_only queue element this will allow a i2c transaction to use multiple data pointers.
** removed direct access to DumpInts(), DumpI2c() from app, use i2cDebug() to set trigger points

@andriyadi found this, total brain fade on my part.
This version no longer needs an interrupt for each byte transferred. It only needs interrupts for START, STOP, FIFO empty/Full or error conditions. This dramatically reduces the interrupt overhead. I think the prior version was causing an interrupt overload condition where the ISR was not able to process every interrupt as they happened.
the 'eject' ERROR is and indication of an interrupt triggering without an source. I am working to eliminate these serviceable interrupt. This update increase stability on a HelTek Wifi Lora 32 board. with a SSD1306 OLED. This update fixes a glaring error in the interrupt allocation code, the Interrupt mask was wrong. I also dynamically adjust the FiFo thresholds based on Bus clockrate. The change to FiFo thresholds has reduced the number for 'eject' events. I also change 'eject' from and ERROR to DEBUG. An 'eject' event does not compromise i2c transmissions. It happens after a transaction has completed.

If Core Debug Level is at DEBUG, a confusing debug message will be emitted if the I2C transaction takes longer complete than the calculated minimum time. This original debug message was just to prove that this new i2c code could correctly handle SCL stretching or interrupt latency issues. This delay is not a problem, or an error. Usually it is caused by a higher priory interrupt starving the i2c ISR. Usually WiFi is the culprit. As long of this delay is within the configured timeout (by default 50ms, or can be set with Wire.setTimeOut(milliseconds);) no problem will occur and the transaction will successfully complete.

This change uses the `_RST` bit of the i2c peripheral to force the hardware into power on reset state. The prior code assumed the peripheral was already in a reset, it just cleared the reset bit.

The existing code did not follow protocol with 10bit addressed devices. Per _Philps/NXP Semiconductors UM10204 I2C-bus specification and user manual Rev. 6 4April2014_ pg.15 3.1.11 10-bit addressing:
~The first seven bits of the first byte are the combination of 1111 0xx of which the last two bits (xx) are the two Most-Significant Bits (MSB) of the 10-bit address; the eighth bit of the first byte is the R/!W! bit the determines the direction of the message~
The i2cWrite() function was returning to the app before the i2c transaction had completed. This caused the next Wire() call to return a I2C_ERROR_BUSY.
* Addition of a i2cReset method and timeout handling for the case where the i2c hardware FSM (state machine) gets stuck in a busy state.
* Use newly added i2cReset function within the wire library.
