It's not possible to programmatically determine which fastboot mode a device is in, without sending a getvar:is-userspace query. Unfortunately this is not possible asynchronously, and may interrupt other queries being processed. This patch changes fastbootd's USB interface name to "fastbootd". Note that tools use the protocol number/class and not this string, so it should be safe to extend. When using "fastboot devices", the interface name is now listed if set. Note that currently only the Linux version of the fastboot tool is capable of reading the interface name. Bug: 156966319 Test: fastboot devices on Linux Change-Id: I57ccf2bec1dda573fe3ac628a646624b76f45905
