[PATCH BlueZ v1 12/12] l2cap-tester: Add SCI mode tests for LE server connections

From: Luiz Augusto von Dentz <[email protected]>

Add L2CAP LE server connection tests that exercise the peripheral
side of the Shorter Connection Interval feature. The emulated client
(central) is configured via bthost_le_conn_rate() to send an LE
Connection Rate Request once connected, using the HOGP v1.2
recommended values for each of the four HID SCI modes (Fast, Default,
Low Power, Full Range).
