We initialize the "struct device" in hci_alloc_dev() for a long time now
so we can access hdev->dev.parent directly. Hence, we can drop the
temporary field hdev->parent which is used in no other place than
hci_add_sysfs().
SET_HCIDEV_DEV() is never called after registering a device by the
drivers so we do not overwrite internal device-state. Furthermore,
hdev->dev is initialized to 0 by kzalloc() inside hci_alloc_dev() so the
default behavior with dev.parent = NULL is kept.

The read_controller_info is typically the first command that user space
sends when taking a controller into use. This is also the reason why
this command has been used as the trigger to set the HCI_MGMT flag.
However, when not running the user-space daemon and using command line
tools it is possible that read_controller_info is not the first
controller specific command. This patch moves the HCI_MGMT

With Bluetooth 1.1 controllers the last command in the HCI init sequence
will be a write_local_name, however there was no callback to indicate
init request completion in this case. This patch fixes the issue by
adding the necessary callback to the write_local_name_complete handler.

Since the clear_uuids operation doesn't send an immediate HCI command
but just sets off a timer to wait for subsequent add_uuid calls it
doesn't make sense to wait until the timer fires off to send the
response. Instead send the response immediately.

This patch adds a flag to track pending changes to the class of device.
This is needed since we cannot cleanly handle multiple simultaneous
commands and need to return a "busy" error status in the mgmt commands
that might trigger a class change.

Since we can now add UUIDs when powered off we don't really need to
always use the service cache to avoid large bursts of HCI commands.
Instead, the only important use case is when we're already powered and
user space starts to initialize itself. This can be easiest detected by
a "clear UUIDs" operation which is where this patch moves the service
cache setting.

Additionally these functions need to be called when the flag is finally

If controller is reset during the discovery procedure, Start Discovery
command stops working. This can be easily reproduced by running
"hciconfig hci0 reset" while discovering devices, for instance.
We should force discovery state to DISCOVERY_STOPPED in case we receive
a reset command complete event. Otherwise we may stuck in one of the
active discovery states (DISCOVERY_INQUIRY, DISCOVERY_LE_SCAN and
DISCOVERY_RESOLVING) and subsequent Start Discovery commands will simply
fail.
