Add command for using MGMT_OP_START_SERVICE_DISCOVERY.

Example usage:
Find all low energy devices advertising service with UUID 'abcd'
that have rssi higher than -60 dB
btmgmt find-service -u abcd -r -60 -l

These three patches have been applied now so we can proceed with getting
the kernel patches tested and upstream (regardless of whether we go with
your original ones or the new ones from Marcel).

I did have to remove the Signed-off-by lines first however since we
don't use that for user space patches.
