tools/console: xenconsole tolerate tty errors
Since 28d386fc4341 (XSA-57), libxl writes an empty value for the
console tty node, with read-only permission for the guest, when
setting up pv console "frontends". (The actual tty value is later set
by xenconsoled.) Writing an empty node is not strictly necessary to
stop the frontend from writing dangerous values here, but it is a good
belt-and-braces approach.
Unfortunately this confuses xenconsole. It reads the empty value, and
tries to open it as the tty. xenconsole then exits.
Fix this by having xenconsole treat an empty value the same way as no
value at all.
Also, make the error opening the tty be nonfatal: we just print a
warning, but do not exit. I think this is helpful in theoretical
situations where xenconsole is racing with libxl and/or xenconsoled.

tools/console: xenconsole tolerate tty errors
Since 28d386fc4341 (XSA-57), libxl writes an empty value for the
console tty node, with read-only permission for the guest, when
setting up pv console "frontends". (The actual tty value is later set
by xenconsoled.) Writing an empty node is not strictly necessary to
stop the frontend from writing dangerous values here, but it is a good
belt-and-braces approach.
Unfortunately this confuses xenconsole. It reads the empty value, and
tries to open it as the tty. xenconsole then exits.
Fix this by having xenconsole treat an empty value the same way as no
value at all.
Also, make the error opening the tty be nonfatal: we just print a
warning, but do not exit. I think this is helpful in theoretical
situations where xenconsole is racing with libxl and/or xenconsoled.
