OBEX Over L2CAP + SDP search API for BT profiles

- Updated OBEX to support SRM
- Added support for OBEX over l2cap and SRM.
- Minor bugfixes, and reduce CPU load ALOT
- Added support to send responses without body data.
- Extend BluetoothSocket to support L2CAP
- Added functionality to get the channel number
  needed to be able to create an SDP record with the channel number.
- Added interface to get socket type and max packet sizes.
- Added interface to perform SDP search and get the resulting
  SDP record data.
