through Bluetooth and Wi-Fi Hotspot.

Technically, if a device has a zero-length device name, the bug will
resurface. The EditText validator doesn't trigger on opening -- only
when the text is edited. A zero-length device name is flagged as being
invalid, but that fails if the text box starts empty.
By pre-filling it with the previous device name, we can ensure that, as
long as a zero-length device name is never set, it can never be set.

The device name is reflected in three places: A Settings.Global flag
which can be read by third party apps, the Bluetooth device name, and
the Wi-Fi tethering hotspot name.
The Bluetooth and Wi-Fi names can be changed independently of the device
name, but if the user sets the device name, they are all changed in
parallel.
Due to the naming restrictions of Bluetooth devices and SSIDs, the SSID
naming restrictions apply to the device name.
