nvvar: Fix creation without value ...

When a new nvvar is added without a value we want to get the value
from the corresponding globalvar. We do this by using nv_set which
ends up freeing the exact string that we passed into nv_set as
value. This results in a corrupt value. Fix this by assigning a
value manually without calling nv_set.

console: fix usbserial re-connect ...

With commit b4f55fcf355a ("console: expose consoles in devfs") consoles
got inserted, but never removed from devfs.
When dealing with USB consoles, barebox should be prepared for devices
spontaneously appering and disappering again (user disconnects and re-
connects the cable). If the devfs entry is not removed upon disconnect,
barebox will raise an error "device creation failed with File exists"
when the cable is connected again.

Remove devfs entries when consoles are de-registered.
Also change the error message, it's the devfs entry.

console: console_get_by_name: do not strcmp NULL ...

console_get_by_name iterates through the console_list using strcmp to mach
a given console by name. console_list may contain entries with devname = NULL,
inserted there e.g. by KEYBOARD_GPIO. In worst case loady -t usbserial
will crash barebox when strcmp hits 0 NULL devname:
> unable to handle NULL pointer dereference at address 0x00000000

Let console_get_by_name just ignore the anonymous consoles.

console_countdown: add possibility to abort countdown by external commands ...

This patch makes it possible to abort a console countdown by an external
command, for example when fastboot is used. This requires additional
