[RFC v2 13/15] Bluetooth: Add thread-safe version of helpers

[Andre Guedes <andre.guedes@openbossa.org>]

This patch adds the thread-safe version of helper functions to add
and remove pending auto connections. These helpers will be used in
next patches to implementing the Mgmt add/remove connection
parameters commands.
