This patch splits the L2CAP command handling function in order to
have a clear separation between the commands related to BR/EDR and
LE. Commands and responses in the LE signaling channel are not being
handled yet, command reject is sent to all received requests. Bluetooth
Core Specification, Volume 3, Part A, section 4 defines the signaling
packets formats and allowed commands/responses over the LE signaling
channel.

Signed-off-by: NGustavo F. Padovan <padovan@profusion.mobi>

Actually doesn't make sense have these modules built separately.
The L2CAP layer is needed by almost all Bluetooth protocols and profiles.
There isn't any real use case without having L2CAP loaded.
SCO is only essential for Audio transfers, but it is so small that we can
have it loaded always in bluetooth.ko without problems.
If you really doesn't want it you can disable SCO in the kernel config.

Some were indirectly set to NO_HT (zero), but I think
