removed packet logging functionality (hci_dump, hexdump) from hci transport implementations and use hci_dump in hci.c instead

add winsock2 for gethostname on win32

release packet buffer after last acl fragment for synchronous HCI transport implementation

reserve buffer in front of incoming hci_packet buffer for h4 (posix, dma, dma+ehcill) and h2 libusb, and acl recombination buffer

fix regression from r2882

le central handle connection update params

cap le acl buffer size, added hci function

implemented L2CAP packet framgentation (in hci.c)

fix generated GAP_LE_ADVERTISING_REPORT

log locally generated gap le adv

number of freed packets sanitized number of completed

added gap_update_connection_parameters

removed cast for btstack_memory_X_get calls

move bt_control_iphone into platforms/ios/src

hci_shutdown_connection moved after calling the packet handler to give upper stack a chance to close down everything with hci_connection_t intact

fix hci_number_free_acl_slots_for_handle to return num free classic slots if no le slots are available. Fixes issue #415

emit dedicated bonding complete after HCI connection is closed, fixed issue #412

use log_info instead of printf, remove trailing newline from log calls

corrected handling of advertising reports

fix compile

keep track of Classic and LE ACL slots seperately

replace hci_number_free_acl_slots with hci_number_free_acl_slots_for_handle

use hci_can_send_prepared_acl_packet_now instead of hci_number_free_acl_slots

use hci_can_send_command_packet_now instead of hci_can_send_packet_now_using_packet_buffer(HCI_COMMAND_DATA_PACKET)

provide new hci_can_send_TYPE_packet_now functions
