Currently, /media is mounted once per boot, which causes issues
if a user need to change USB sticks, or unknowning performs an
operation that mounts /media and then needs to access a different
USB stick later (eg, updating the firmware).
To mitigate this, always unmount /media if mounted before scanning
for USB devices, so the user can choose the correct device at the
time of its use.
Additionally, add a unique exit code for user abort so we're not
treating it the same as a failure, and use it to prevent unnecessary
GUI prompts when cancelling selection of a USB device.

Rather than wait a fixed 5s for the usb storage kernel modules
to load, and the user to insert a drive, check for new USB drives
inserted every 1s with a 5s timeout.

Currently Heads relies on a hard-coded config value to determine which
USB disk to mount. This can be problematic when trying to distribute a
pre-built version of Heads that can work on multiple disk
configurations. I've modified the USB mounting script so that it
attempts to detect all USB boot disks present on the system, pick sane
defaults, and prompt the user when there are multiple choices.
I've also removed the USB configuration option from config-gui.sh as
this config option is no longer used.
USB smart card readers are most full speed devices, and there is no
"rate-matching hubs" beneath the root hub on older (e.g. GM45) plat-
forms, which has companion OHCI or UHCI controllers and needs cor-
responding drivers to communicate with card readers directly plugged
into the motherboard, otherwise a discrete USB hub should be inserted
between the motherboard and the reader.
This time I make inserting linux modules for OHCI and UHCI controllable
with option CONFIG_LINUX_USB_COMPANION_CONTROLLER.
A linux config for x200 is added as an example.
Tested on my x200s and elitebook revolve 810g1.
