Included support for LE data packet extension feature according
to BT 4.2 spec. This patch checks if the controller supports LE
packet extension and provides functions to set the PDU length.

This fixes a few changes that was reverted by mistake,
causing uninitialized data to be used as instance data
in GAP and no buffers allocated to the L2CAP sockets.

As a part of BT 4.1 stack upgrade, added host support for BR/EDR
secure connections to be able to interact with controllers that
support secure connections and upgrade the SSP mechanism to use
secure connection rules.

This change checks for controller support in the extended_features
(LMP page 2) and then declares the host support (extended_features
LMP page 1) using WRITE SECURE CONNECTIONS HOST SUPPORT.
If both the sides support secure connections, the simple pairing
process utilizes the link key generated using P-256 elliptic curve
(in the controller) and both the sides will be
in a secure connection.

Enable support for numeric comparison in SMP when LE Secure connection
is supported. The change will distinguish between passkey confirmation
in case of Security grant and Passkey confirm.

Added support for exposing L2CAP to Java such that OBEX over L2CAP
is made possible.

Added support to create SDP records as a seperate step.(as opposed to
creating a SDP record when a BluetoothSocket is created).
This allows both a RFCOMM channel and a L2CAP PSM to be included in a
SDP record. (Additionally the content of the SDP record is set by the
profile in Java, in stead of beeing hardcoded in the socket layer.)
This completes the L2CAP channel exposure to Java.

  Don't truncate the top 16 bits of the LE advertisement data mask.

* commit 'f2a30784':
  Don't truncate the top 16 bits of the LE advertisement data mask.

This is stored elsewhere as unsigned 32-bit integer.
It should be stored the same way here.

(cherry picked from commit 79fb0912)

Fixed channel connections are getting a disconnect callback when the
HCI command is issued and when the HCI disconnect completes. This
causes problems if the upper layer trying to reconnect at link
disconnecting state.
Triggering the disconnect callback only once solves this problem.

BTA_AvEnable_Sink() was being called to early causing
a crash loop when the BT AV_SINK was included. This patch
changes up the init sequence to match that of the av
source. Also, rename a few constants for clarity.
