The hci_connect() function was starting to get too complicated to be
quickly understood. We can separate the creation of a new ACL
connection into its own function.

Currently we have no way to assign tty->port while performing tty
installation. There are two ways to provide the link tty_struct =>
tty_port. Either by calling tty_port_install from tty->ops->install or
tty_port_register_device called instead of tty_register_device when
the device is being set up after connected.
In this patch we modify most of the drivers to do the latter. When the
drivers use tty_register_device and we have tty_port already, we
switch to tty_port_register_device. So we have the tty_struct =>
tty_port link for free for those.

If the device was not found in a list of found devices names of which
are pending.This may happen in a case when HCI Remote Name Request
was sent as a part of incoming connection establishment procedure.
Hence there is no need to continue resolving a next name as it will
be done upon receiving another Remote Name Request Complete Event.
This will fix a kernel crash when trying to use this entry to resolve
the next name.

This patch changes hci_cs_le_create_conn to perform hci_conn lookup
by state instead of bdaddr.
Since we can have only one LE connection in BT_CONNECT state, we can
perform LE hci_conn lookup by state. This way, we don't rely on
hci_sent_cmd_data helper to find the hci_conn object.

This patch does some code refactoring in hci_cs_le_create_conn
function. The hci_conn object is only needed in case of failure,
therefore hdev locking and hci_conn lookup were moved to
if-statement scope.
Also, the conn->state check was removed since we should always
close the connection if it fails.

This patch removes some unneeded code from hci_cs_le_create_conn.
If the hci_conn is not found, it means this LE connection attempt
was triggered by a thrid-party tool (e.g. hcitool). We should not
create this new hci_conn in LE Create Connection command status
event since it is already properly handled in LE Connection
Complete event.

lsof command can tell the type of socket processes are using.
Internal lsof uses inode numbers on socket fs to resolve the type of
sockets. Files under /proc/net/, such as tcp, udp, unix, etc provides
such inode information.
Unfortunately bluetooth related protocols don't provide such inode
information. This patch series introduces /proc/net files for the protocols.
This patch against af_bluetooth.c provides facility to the implementation
of protocols. This patch extends bt_sock_list and introduces two exported
function bt_procfs_init, bt_procfs_cleanup.
The type bt_sock_list is already used in some of implementation of
protocols. bt_procfs_init prepare seq_operations which converts
protocol own bt_sock_list data to protocol own proc entry when the
entry is accessed.
What I, lsof user, need is just inode number of bluetooth
socket. However, people may want more information. The bt_procfs_init
takes a function pointer for customizing the show handler of
seq_operations.
In v4 patch, __acquires and __releases attributes are added to suppress
sparse warning. Suggested by Andrei Emeltchenko.
In v5 patch, linux/proc_fs.h is included to use PDE. Build error is
reported by Fengguang Wu.

This patch is based on a user space (hciops) patch which never made it
upstream but does make sense to include in the mgmt part of the kernel.
(User space) commit message from Dmitriy Paliy:
"
Page scan interval in fast connectable mode is changed from 22.5 msec to
160 msec to perform less aggressive page scanning. This is done
accordingly to controller vendor recommendation.
Primary concern is that current parameters 22.5 interval, 11.25 window,
and interleaved scanning occupy whole radio bandwidth. Changing interval
to 160 msec should be sufficient for both speeding up connection
establishment and leaving space for other activities, like inquiry scan,
e.g.
