Subject: Add fastboot mode to recovery

Add a fastboot mode to recovery that can be
entered with command line args or with the ui.

Add usb property triggers to switch between
fastboot and adb configurations.

Allow switching between fastboot and adb through
usb commands by opening a unix socket. adbd/fastbootd
writes to this socket, which interrupts the ui and
switches to the new mode.

Test: Use fastboot mode
