Bluetooth: Split hci_request helpers to hci_request.[ch] None of the hci_request related things in net/bluetooth/hci_core.h are needed anywhere outside of the core bluetooth module. This patch creates a new net/bluetooth/hci_request.c file with its corresponding h-file and moves the functionality there from hci_core.c and hci_core.h.

Bluetooth: Add second hci_request callback option for full skb This patch adds a second possible callback for HCI requests where the callback will receive the full skb of the last successfully completed HCI command. This API is useful for cases where we want to use a request to read some data and the existing hci_event.c handlers do not store it e.g. in the hci_dev struct. The reason the patch is a bit bigger than just adding the new API is because the hci_req_cmd_complete() functions required some refactoring to enable it: now hci_req_cmd_complete() is simply used to request the callback pointers if any, and the actual calling of them happens from a single place at the end of hci_event_packet(). The reason for this is that we need to pass the original skb (without any skb_pull, etc modifications done to it) and it's simplest to keep track of it within the hci_event_packet() function.

Bluetooth: Add hci_request support for hci_update_background_scan Many places using hci_update_background_scan() try to synchronize whatever they're doing with the help of hci_request callbacks. However, since the hci_update_background_scan() function hasn't so far accepted a hci_request pointer any commands triggered by it have been left out by the synchronization. This patch modifies the API in a similar way as was done for hci_update_page_scan, i.e. there's a variant that takes a hci_request and another one that takes a hci_dev.
