disconnect with 0x13 after dedicated bonding

add gap_set_local_name and mark local_name as const

trigger hci_run after setting auth req bonding flag

fix condition for ssp io cap negative reply

removed debug printf

add hci_disable_l2cap_timeout_check() for testing

added hci_connection_for_bd_addr

added hci_set_class_of_device

alloc hci_stack structure if malloc is provided - reduces static memory consumption and saves RAM if BTstack isn't activated

renamed btstack config.h to btstack-config.h to allow for better integration with other projects

use SSP_IO_AUTHREQ_MITM_PROTECTION_NOT_REQUIRED_GENERAL_BONDING as default

don't modify ssp auth req for gap_request_security_level

don't modify ssp authreq for dedicated bonding

support dedicated bonding and provide example for it

track legacy and ssp pairing, new implementation for hci_authentication_active_for_handle based on that

rename HANDLE_PIN_CODE_REQUEST TO DENY_PIN_CODE_REQUEST

don't send encryption command if authentication failed

if both devices support SSP, initiator shall setup unauthenticated link unless connecting to SDP

GAP update to higher security level working

reject l2cap connection if secruity level not reached after auhentication

successfully enable encryption if security level 2 is requested for l2cap service

allow to send connection encryption command

fix sending of Connection Result - Pending, request authentication if security level isn't enough

request security level 0 for l2cap services

reject connection (0x03 security block) if both have SSP, PSM != SDP, and connection is not ecncrypted
