the SIOCGBTFEAT ioctl (no change in size)

fix parameter types in pr_ioctl, called xx_control() functions and remove
abuse of pointer to struct mbuf type.

param2 changed to u_long type and uses parameter name 'cmd' (ioctl command)
param3 changed to void * type and uses parameter name 'data'
param4 changed to struct ifnet * and uses parameter name 'ifp'
param5 has been removed (formerly struct lwp *) and uses of 'l' have been
replaced with curlwp from curproc(9).

callers have had (now unnecessary) casts to struct mbuf * removed, called
code has had (now unnecessary) casts to u_long, void * and struct ifnet *
respectively removed.

* split PRU_CONTROL functionality out of xxx_userreq() switches and place
into separate xxx_ioctl() functions.
* place KASSERT(req != PRU_CONTROL) inside xxx_userreq() as it is now
inappropriate for req = PRU_CONTROL in xxx_userreq().
* replace calls to pr_generic() with req = PRU_CONTROL with pr_ioctl().
* remove & fixup references to PRU_CONTROL xxx_userreq() function comments.
* fix various comments references for xxx_userreq() that mentioned
PRU_CONTROL as xxx_userreq() no longer handles the request.

a further change will follow to fix parameter and naming inconsistencies
retained from original code.

Clean up the way that bluetooth drivers attach to the bluetooth stack,
to remove the frobbing that drivers must do in the hci_unit structure.

- driver provides a static const interface descriptor
- hci_unit is allocated by hci_attach() rather than part of softc
- statistics are compiled by driver and provided on request
- driver provides output methods and is responsible for output queue
- stack provides input methods and is responsible for input queue
- mutex is used to arbitrate device queue access

use more device_t and device_xxx() accessors

make bluetooth stack keep device_t instead of softc pointer as
device is not necessarily part of softc, and pass device_t to
driver callbacks. hci_devname is no longer required.

hci_event.c:
- Convert memo->response.clock_offset to host-endian.

hci_ioctl.c:
- printf format tweak (size_t)

hci_link.c:

l2cap_signal.c:

we convert from host-endian.
