Having the HCI_AUTO_OFF flag set means that from a mgmt interface
perspective we're still not powered, so all tests for HCI_UP should also
include a test for HCI_AUTO_OFF. This patch adds a convenience macro for
it.

Marcell Zambo and Janos Farago noticed and reported that when
new conntrack entries are added via netlink and the conntrack table
gets full, soft lockup happens. This is because the nf_conntrack_lock
is held while nf_conntrack_alloc is called, which is in turn wants
to lock nf_conntrack_lock while evicting entries from the full table.
The patch fixes the soft lockup with limiting the holding of the
nf_conntrack_lock to the minimum, where it's absolutely required.

When a new controller gets added to the system, it needs to be brought
up briefly to read basic information like features, BD_ADDR etc. and
after a timeout it will be brought back down.
The only command that should overwrite this timeout is the set power
command from the management interface. Just reading the controller
list or information is not a good reason to keep the controller up.

Any HCI raw socket gets a copy of each SKB that is either received or
send via the Bluetooth subsystem. The raw socket uses SKB clones to
send out data, but the problem is that it needs to add an extra packet
type byte in front of it. And some drivers need to also add an extra
header before submitting the packet.
So far this all worked magically fine since all of the drivers and the
raw sockets are adding the same byte at the same location. But that is
by pure coincidence. Since the data of cloned SKBs is shared, this means
that the raw socket and driver kept writing into the shared data area.
To fix this the only safe way is if the HCI raw socket creates a copy of
the SKB before sending it out. To not always copy all SKBs around, the
copy is only created once and only after any of the HCI filter checks
succeeded.

commit 50612537e9 (netem: fix classful handling) added two errors in
netem_dequeue()
1) After checking skb at the head of tfifo queue for time constraints,
it dequeues tail skb, thus adding unwanted reordering.
2) qdisc stats are updated twice per packet

The hci_connect function should either return a valid hci_conn pointer
or a ERR_PTR() but never NULL. This patch fixes the two places where
hci_conn_add failures would have caused a NULL return. The only reason
for failure with hci_conn_add is memory allocation so ENOMEM seems to be
a good choice here.

This patch merges DISCOVERY_INQUIRY and DISCOVERY_LE_SCAN states
into a new state called DISCOVERY_FINDING.
From the discovery perspective, we are pretty much worried about
to know just if we are finding devices than what exactly phase of
"finding devices" (inquiry or LE scan) we are currently running.
Besides, to know if the controller is performing inquiry or LE scan
we should check HCI_INQUIRY or HCI_LE_SCAN bits in hdev flags.
Moreover, merging this two states will simplify the discovery state
machine and will keep interleaved discovery implementation simpler.

This patch does some code refactoring in start_discovery function
in order to prepare it for interleaved discovery support.
MGMT_ADDR_* macros were moved to hci_core.h since they are now used
to define discovery type macros.
Discovery type macros were defined according to mgmt-api.txt
specification:
Possible values for the Type parameter are a bit-wise or of the
following bits:
1 BR/EDR
2 LE Public
3 LE Random
By combining these e.g. the following values are possible:
1 BR/EDR
6 LE (public & random)
7 BR/EDR/LE (interleaved discovery)

The svcrdma transport was un-marshalling requests in-place. This resulted
in sparse warnings due to __beXX data containing both NBO and HBO data.
The code has been restructured to do byte-swapping as the header is
parsed instead of when the header is validated immediately after receipt.
Also moved extern declarations for the workqueue and memory pools to the
private header file.
