raspi: avoid warning by adding explicit default

port: avoid HCI_EVENT_IS_COMMAND_COMPLETE macro

port: use btstack_strcpy and btstack_cat instead of strcpy/strcat

libusb, posix and windows ports: use '-' instead of ':' in btstack_BD_ADDR.tlv filename

libusb, posix and windows ports: use '-' instead of ':' in btstack_BD_ADDR.tlv filename

license: update text

posix: use bstack_signal to trigger shutdown for ctrl-c

hci_transport: extract convenience function declaration for h4, h5, em9304_spi, and usb into separate hci_transport_{type}.h

hci_dump: use hci_dump_posix_fs with PacketLogger format in all posix ports

ports: disable hci dump in all ports

h5 ports: use btstack_uart_posix without slip wrapper

h5 ports: use uart slip wrapper for posix-h5, posix-h5-bcm, raspi, wiced-h5, pic32-harmony

raspi: switch to TLV for link key and le device db, allow to compile without classic

raspi: use warm boot if ENABLE_CONTROLLER_WARM_BOOT is defined

raspi: detect raspberry pi model, use 3 mbps for 3A+ and 3B+

raspi: support for Pi 3 A+/B+, power cycle only controller without flowcontrol

raspi: support for Pi 3 A+/B+, power cycle only controller without flowcontrol

raspi: use H4 for Raspberry Pi Zero W with Hardware UART / Flow Control

raspi: BT_REG_EN on GPIO 45 on Pi Zero W

raspi: use TLV with btstack_tlv_posix

raspi: shorten power cycle, switch back to /lib/firmware/brcm

raspi: fix serial number parsing

raspi: power cycle Bluetooth controller on start

raspi: fix compile

raspi: fix compile, look for BCM43430A1.hcd in /lib/firmware/
