requirement: A Long Press of ASR should restart ASR.

actual: ASR is cancelled as soon as ASR button is pressed, regardless of longpress state.

Protocol spec says we should just use reportKey sending key downs and key ups, but as soon as key down is sent ASR is cancelled.

If we send reportKeyLongPress instead, then ASR is again cancelled immediately.

Note also - HUIG 2.7 appears to contradict the protocol spec with regards the use of reportKeyLongPress...

10.2.2: Long-Press
The HU MUST use the reportKeyLongPress function to send the KEYCODE_SEARCH keycode to the MD to initiate an AAP session (R10-130).

However protocol spec states:
"Used to signal a long press of a button by simulating a key down, hold, key up on the phone. Do not report a key up after setting this flag. This should only be used if the system cannot signal the initial key down. Contact the GAL team before you decide to set this flag."

and also HUIG
10.2.3 Cancelling or restarting an ASR session
KEYCODE_SEARCH keycode MUST be sent using the reportKey function as soon as the ASR hardware button is pressed down
