Following the separation if core and sock code this change avoid
manipulation of sk inside l2cap_chan_create().

The L2CAP timeout constants are always used in form of jiffies. So just
include the conversion from msecs in the define itself. This has the
advantage of making the code where the timeout is used more readable.

Change sk lock to chan lock in l2cap core and move sk locks
to l2cap sock code. bh_locks were used because of being RCU
critical section. When needed use explicit socket locks.

Usage of RCU list looks not reasonalbe for a number of reasons:
our code sleep and we had to use socket spinlocks. Most parts
of code are updaters thus there is little sense to use RCU.

sk_sndtime value should be specified in jiffies thus initial value
needs to be converted from miliseconds. Otherwise this timeout is
unreliable when CONFIG_HZ is not set to 1000.

This move some checking code that was in l2cap_sock_connect() to
l2cap_chan_connect(). Thus we can invert the lock calls, i.e., call
lock_sock() before hci_dev_lock() to avoid a deadlock scenario.

Some incomming connections needs to increase the security level by
requesting encryption for example (HID keyboard case). This change allows
the userspace to change it through setsockopt with defer_setup enabled.

tx_win_max is initialized during L2CAP configuration phase. For fixed
channels (e.g. A2MP) we want to have it initialized when channel is
created.

These files are non modular, but need to export symbols using
the macros now living in export.h -- call out the include so
that things won't break when we remove the implicit presence
of module.h from everywhere.
