The call to l2cap_chan_clear_timer() is not really needed in l2cap_sock.c.
This patch also adds a call to l2cap_chan_clear_timer() to the only place
in __l2cap_sock_close() that wasn't calling it. It's safe call it there
because l2cap_chan_clear_timer() check first for timer_peding().

The new timer does not belong to struct sock, tought it still touch some
sock things, but this will be sorted out soon.

A new list was added to replace the socket based one. This new list
doesn't depent on sock and then fits better inside l2cap_core.c code.

It also rename l2cap_chan_alloc() to l2cap_chan_create() and
l2cap_chan_free() to l2cap_chan_destroy)

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.
