Separate LE scanner from GATT client (3/4)

Browse source 
Right now, LE scanning functionality is combined with the GATT client.
This is the source of various bugs, like scans suddenly stoppinging when
a GATT client is killed. It also increases memory consumption, because
we associate many structures with a GATT client, which are not necessary
when just scanning.
