port/arduino: set h4 config, register hci packet handler for advertisements and connection events

arduino: rework Makefile and update BTstack C++ wrapper for 1.0 API

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

hci_dump: arduino port

fix compile

hci: provided error code in hardware error callback

hci_transport/btstack_uart_block: create btstack_uart_block_embedded on top of hal_uart_dma. Pass in uart driver to H4/H5 instances

use btstack_event_state_get_state

java: use streamline event names, GAP_LE_EVENT_ADVERTISING_REPORT -> GAP_EVENT_ADVERTISING_REPORT

event: introduce hci_event_packet_get_type

use hci_con_handle_t more

use hci_con_handle_t more

gatt_client: prefix gatt structs with gatt_client

gap.h: use gap_ instead of le_central_ or gap_le_

att -> att_db

hci: set link_key_db via hci_set_link_key_db instead of via hci_init().

util.h: rename swapX into reverse_x

util.h: new names uuid_has_bluetooth_prefix();uuid_add_bluetooth_prefix()

fix typo in big_endian_read_32

sm, att_server: don't forward events from lower layers.

use little/big_endian_read/store_16/24/32

use for event types

hci_transport: cleanup struct, add init(void *transport_config)

remove btstack_control_h from hci_init. mark btstack_control, hci_transport, and hci_transport_config as const

renamed bt_control_chipsetname into btstack_chipset_chipsetname. fix some builds
