Thomas Zimmermann cd5cc34c31 Bug 891866: Implement RegisterAgent with asyncronous functions, r=echou,gyeh
RegisterAgent currently blocks the Bluetooth command thread while
waiting for DBus. This patch moves the result-handling code into a
DBusReplyHandler, and executes an asyncronous DBus call.

/**
* Some rules for dealing with memory in DBus:
* - A DBusError only needs to be deleted if it's been set, not just
* initialized. This is why LOG_AND_FREE... is called only when an error is
* set, and the macro cleans up the error itself.
* - A DBusMessage needs to be unrefed when it is newed explicitly. DBusMessages
* from signals do not need to be unrefed, as they will be cleaned by DBus
* after DBUS_HANDLER_RESULT_HANDLED is returned from the filter.
