Gustavo F. Padovan 525cd1851b Bluetooth: Move conn_state to struct l2cap_chan
This is part of "moving things to l2cap_chan". As one the first move it
triggered a big number of changes in the funcions parameters, basically
changing the struct sock param to struct l2cap_chan.

Use a well known Kernel API is always a good idea than implement your own

Gustavo F. Padovan 48454079c2 Bluetooth: Create struct l2cap_chan
struct l2cap_chan cames to create a clear separation between what
properties and data belongs to the L2CAP channel and what belongs to the
socket. By now we just fold the struct sock * in struct l2cap_chan as all
the channel info is struct l2cap_pinfo today.

In the next commits we will see a move of channel stuff to struct
l2cap_chan.

Suraj Sumangala 23e9fde2b3 Bluetooth: Increment unacked_frames count only the first transmit
This patch lets 'l2cap_pinfo.unacked_frames' be incremented only
the first time a frame is transmitted.

Previously it was being incremented for retransmitted packets
too resulting the value to cross the transmit window size.

Andrei Emeltchenko e90165be9a Bluetooth: check L2CAP info_rsp ident and state
Information requests/responses are unbound to L2CAP channel. Patch
fixes issue arising when two devices connects at the same time to
each other. This way we do not process out of the context messages.
We are safe dropping info_rsp since info_timer is left running.

Gustavo F. Padovan 642745184f Bluetooth: Merge L2CAP and SCO modules into bluetooth.ko
Actually doesn't make sense have these modules built separately.
The L2CAP layer is needed by almost all Bluetooth protocols and profiles.
There isn't any real use case without having L2CAP loaded.
SCO is only essential for Audio transfers, but it is so small that we can
have it loaded always in bluetooth.ko without problems.
If you really doesn't want it you can disable SCO in the kernel config.
