[PATCH v3 00/18] Rework HIDP Session Management

[David Herrmann <dh.herrmann@gmail.com>]

Hi

This is v3 of the HIDP session management rework. Only thing that changed is
that I moved hci_conn_user to l2cap_user as requested. The l2cap_user object is
now bound to l2cap_conn objects instead of hci_conn. This avoids any direct HCI
dependency in external modules.

Note that this requires l2cap_conn ref-counting. However, this is pretty easy to
implement and does not affect existing code at all as we use direct
synchronization.

Also note that I designed it in a way that it is independent of l2cap_sock. So
if we succeed it making l2cap_core independent of l2cap_sock, we can move HIDP
or other l2cap_user users over and make them independent of l2cap_sock, too.

Regards
David
