Before we send or respond to a ConnectionRequest, we ask SecurityManager
to enforce that we have sufficient link layer security.

SecurityManager needs to implement SecurityModuleInterface, and inject
the implementation to L2cap module. L2cap provides a default
implementation which rejects all connection which requires link key.

Add the API for L2CAP channel user to get/set link layer options, such
as connection parameter update, and get role.

Add the corresponding PTS test case for it. The next step is to
determine the command from remote feature.

Currently there is coupling between sender, scheduler, and receiver.
Instead, use DataPipelineManager to orgranize them.

Scheduler is used for enqueuing PDUs from segmenters to link queue end.
Segmenter is used for dequeuing SDUs from channels to scheduler.
Segmenter needs to handle converting PDUs into SDUs.

Previously Scheduler handles both outgoing and incoming packet path, but
they are actually not related to each other. Separating them to
decouple. Now Scheduler only serves outgoing packets, and the new
Reassembler serves incoming packets.

Currently only basic mode is supported. When we add enhanced retransmission
mode, we add logic to it separately.

* Although L2CAP LE and Classic stacks look similar, they are actually very different when diving into details
* Splitting them into two separate modules will benefit in the following ways:
 * One can start a LE only stack
 * One can turn off Classic stack entirely when not needed
 * Dependencies are more obvious, e.g. LE-CoC only depends on LE L2CAP and A2DP only depends on Classic L2CAP
* Changed test names as GTEST does not allow test name collisions
* New directory structure after the change:
  - l2cap: common headers that should be exposed to public
    - internal: common internal libraries shared between LE and classic
    - classic: classic headers that should be exposed to public
      - internal: internal libraries for classic
      - cert: certification stack for classic
   - le: LE headers that should be exposed to public
      - internal: internal libraries for LE
      - cert: certification stack for LE
