Add ioctl's for the bluetooth authentication

Browse Source 
For dive computers which are using an application specific proprietary
pairing mechanism instead of the standard bluetooth pairing, we need to
be able to exchange some additional information with the application.
Therefore, 3 new BLE specific ioctl's are added:

When a device has not been paired yet, libdivecomputer will request the
PIN code from the application with DC_IOCTL_BLE_GET_PINCODE. Once the
device has been paired successfully, the access code is passed back to
the application with DC_IOCTL_BLE_SET_ACCESSCODE. On the next download,
libdivecomputer will request this access code again from the application
with DC_IOCTL_BLE_GET_ACCESSCODE. If no access code is available, the
pairing procedure will start again by requesting the PIN.
