This required advancing the IpManager to IpClient refactoring
(Bluetooth used IpManager and friends). Most importantly, the
Bluetooth code used WaitForProvisioningCallback, so this is
moved into IpClient proper now. Also: some more renaming
cleanup.
Test: as follows
- built
- flashed
- booted
- runtest frameworks-net passes
