L2CAP LE socket is added in Android from Q and these two patches
implements for ARC++.

The code for this new socket is quite similar to the existing code for
RFCOMM. Since we cannot just change the name of an existing interface,
in the next patch, we will add two new interfaces (listen and connect
socket) which can be used for both RFCOMM and L2CAP, and deprecates the
old ones, when both P and R get the corresponding patch(es).

This patch doesn't change any functionalities. It just refactors the
current code a bit, including:
- Renaming RFCOMM-specific stuff into more generic ones;
- Changing to calling bind() for both listen and connect sockets:
  calling bind() for RFCOMM connect sockets is not required but needed
  by L2CAP LE sockets;
- Changing type of |channel| in some methods to uint16_t for PSM value;
- Fixing a wrong usage of PLOG.
