L2CAP: Major refactor of the whole component.

(And surrounding portions of the "btCoreData" module.)

* Rewrote the main "l2cap.h" header representing protocol constants
and structures. Now conforms to general Haiku naming conventions
rather than BSD ones. Some more constants added/removed based
on the most recent Bluetooth specification.

* Rewrote all code derived from the BSDs to match Haiku conventions
and structures in the driver.

* Dropped the "channel" and "frame" structures from "btCoreData".
Channels are now managed by L2capEndpoints, and "frames" are
now just plain net_buffers without surrounding structures.
This also makes state management much simpler.

* Made it so that actual net_buffers are passed through to the
l2cap_receive function rather than another data structure.
A fake interface address is used to communicate connection
information. (This probably ought to be changed, though.)

* Get rid of l2cap_lower and l2cap_upper abstractions.
Everything related to channel/endpoint management is now
done in L2capEndpoint, while buffer reception is handled
directly in l2cap_receive and elsewhere, same as other drivers.

* Wire up more hooks and fix module flags (needed to be able to
get the module loaded and opening sockets at all.)

* Implement an actual locking strategy in L2capEndpoint
and HciConnection. There's still problems with lifetime
management, but at least thread-safety is mostly handled.

* Create an L2capEndpointManager and use it to manage
the endpoints, rather than having a single (unsafe)
linked-list.

And plenty of other refactorings and cleanups besides.
There's still more to be done for Bluetooth overall, though:

* The "btCoreData" and "hci" modules also badly need a major
overhaul, and should be merged into a single "bluetooth"
bus_manager. They also shouldn't be passing around pointers
to other modules like this.

* There's a number of TODOs/FIXMEs in the L2CAP module, most
notably around timeouts (especially command timeouts) and
parameter validation/specification.

Tested by myself and kallisti5. Outgoing connections,
at least, manage to fully initialize and configure
successfully.

(on the PSM for SDP) get all the way to the latter half
of the Configuration step before hanging.

Current L2CAP code. Replying ConnectionResponses signals. The style should be more acurate than my previous commits(so use this commit to correct my remaining bad habits). The Code is not completed but need to commit to have a chance to go on from Germany....
