Update to joystick and example

Support to pair PS3 if it knows the BTADDR and user presses select and PS button and plugged in USB.

Remembers remote name, and tries to get it when PAIR version of code is running.  (Currently fails).

Does some mapping of PS3 Bluetooth data to match USB HID data.

Warning: as part of debuggigng why joystickType value was changing, I changed the class to make it a function you call instead of just a member variable.  Should mark it inline...  I think I caught all of the places in example code that was accessing it.  If we find we want ability for user probram to update it, should add another member to explicityly set it.

I have some PS3 support working... Hope I did not break PS4.... ;)

Also This assumes that you did a bind of the dongle to PS3 external, no support yet, I did this on RPI3...

Rumble needs work!

Updated Joystick, examples and added sixaxis code

Hopefully did not break other things...

Find that the PS4 requires you to ask to connect versus some/most other devices will do the request...

Also found issue without printing, where adding a delay(1) in a couple of places appears to help when Serial1 printing is not on

Was issues not detecting that ISR bind was asked for, also not special casing when we are doing a bind to know which message to send next....

At least with the Tecknet mouse...

There are issues with binding when already trusted... Need to debug, also likewise if it times out and tries to restore the connection, but at least the beginning is getting some values

I put in hopefully the start of Bluetooth Mouse.

However the one mouse I have is not even trying to talk to the dongle, so not have not seen any data to verify that it is correct and to see the actual data returned...

There are some of the BT dongles that have a device type of 0xff instead of the correct one, so added table of VID:PID to check against, currently only one in list.  If it is this pair the Bluetooth system will claim it.

PS4 starting to work, Still some rumble issues.

Also some WIP parts for caching remote name

Some of these changes also came from @mjs513

Updated wiht my ps4 BT changes

Hopefully not everything screwed up... :D

Now only optionally force keyboard into boot protocol mode

Serial CP210x support for more boards

Updated some of the init code for the CP210x.

Before it worked with the one USB to serial adapter I had, but
we foudn it id did not work with Adafruit USB adaptor nor with their metro boards

The first gigabyte fix, was to always force the keyboard into boot protocol mode, which appeared to work well for all of the keyboards I tried.

Unforationally it caused issues with some wireless keyboard/mouse combo packages, including some logitech and some microsoft keyboards.

This version instead, I created a list (currently only one vendor id), of vendor id:product id, that need to be forced into boot mode.  Knowing that if there is one keyboard vendor with this N key rollover feature, there are probably others.  So while this list can be expanded, this requires users to update library.  So added a method forceBootProtocol method to keyboard class that allows the user to try it out without needing to update the library sources.

The mouse test program has example of either setting it before the keyboard is initiated, as well as another way that when a connection is found it asks for the vendor id, and if it is the one of my gigabyte keyboard, it calls the function then.

While doing this I found some of the query functions like idVendor on the keyboard class would not compile as the keyboard object has multiple inheritence and both base classes have this.  So like the joystick objects I added these to the top level function and these functions will direct the calls to the approrpriate places.

Fix/workaround for Gigabyte keyboard

The gigabyte keyboard has an N key rollover input, that is different than all of our current keyboards.

So this code tells (currently All) keyboards to choose their boot protocol, which gets us back to the standard boot definition.  Which alllows these keyboards to function like others.

XBox360 Wireless controller

Support for using the Microsoft XBox 360 wireless receiver for windows
to be able to communicate with XBox 360 wireless controllers.

In theory this should support up to 4 controllers.  So far I have only
tested with one as I only have one.

Added a joystick only test that should support up to 4 joystick objects.

Still working on PS4

Again still WIP - but now have the Bluetooth object talking through a keyboard object...

With this update, I can now talk to the keyboard without having to repair each time.

Still WIP

Code is still WIP, needs lots of reorg and fix up and lots more to figure out.

But started working toward the Bluetooth HID devices and have the messages going back and forth from my BT dongle to a small BT keyboard.
It is finally showing keys being pressed and the like.

Code needs lots of work.  Like does pairing everytime, need to make that optional.

Also need to figure out where to split off the HID stuff from Root BT stuff.  ...

Plus it mainly prints lots of debug information.
