Praveen K Paladugu a8fa2af64b vmm: dup serial fds to preserve them across reboots ...

During vm_shutdown or vm_snapshot, all the console devices will be
closed. When this happens stdout (FD #2) will also be closed as the
console device using these FD is closed. If the VM were to be started
later, FD#2 can be assigned to a different file. But
pre_create_console_devices looks for FD#2 while opening tty device,
which could point to any file.

To avoid this problem, the STDOUT FD is duplicated when being
assigned to a console device. Even if the console devices were to be
closed, the duplicated FD will be closed and FD#2 will continue to
point to STDOUT.
