SMPKeyBin (C++/Java): Add 'apply(BTDevice&)' method, setting Security params and uploading available LTKs
Moving the SMPKeyBin setup and key-upload for the BTDevice to public SMPKeyBin,
providing the proper setup and upload method.
One change compared to removed coding in Scanner10 example occured:
"BTSecurityLevel::ENC_ONLY is set to avoid a new SMP PairingMode negotiation,
which is undesired as this instances' stored LTK shall be used for PairingMode::PRE_PAIRED."
i.e.: 'device.setConnSecurity(BTSecurityLevel.ENC_ONLY, SMPIOCapability.NO_INPUT_NO_OUTPUT);'
This has been evaluate with a Secure Connections capable LE device
using BTSecurityLevel::ENC_AUTH_FIPS and SMPIOCapability::KEYBOARD_ONLY.
After initial pairing using a dynamic generated passkey,
we connected successfully and stored the LTKs and CSRKs with this connection parameter.
Thereafter reconnect after setting (BTSecurityLevel.ENC_ONLY, SMPIOCapability.NO_INPUT_NO_OUTPUT)
and uploading stored keys succeeded with Linux Kernel-BlueZ host implementation.
