Add advertising support (start with set-data and -params, stop) via HCIHandler

Reasonable default values have been chosen from the BT spec,
which can be overriden using the HCIHandler and BTAdapter operations.

The extended advertising operations are also supported (Bluetooth 5.0).

Successfully tested running:

(0) Test machine with 2 adapter
    - adapter-1 DC:FB:48:00:90:19 (acting as client)
    - adapter-2 00:1A:7D:DA:71:08 (acting as peripheral)

(1) Running dbt_peripheral00.cpp or DBTPeripheral.java
    as the advertising peripheral on the test machine.

    `direct_bt/dist-amd64$ ../scripts/run-dbt_peripheral00.sh -adapter 00:1A:7D:DA:71:08`

    or

    `direct_bt/dist-amd64$ ../scripts/run-java-peripheral00.sh -adapter 00:1A:7D:DA:71:08`

(2) Running dbt_scanner10.cpp or DBTScanner10.java
    as the listeninig and connection-initiator client
    on the same test machine.

    `direct_bt/dist-amd64$ sh ../scripts/run-dbt_scanner10.sh -adapter DC:FB:48:00:90:19 -dev 00:1A:7D:DA:71:08 -seclevel 00:1A:7D:DA:71:08 1`

    or

    `direct_bt/dist-amd64$ sh ../scripts/run-java-scanner10.sh -adapter DC:FB:48:00:90:19 -dev 00:1A:7D:DA:71:08 -seclevel 00:1A:7D:DA:71:08 1`
