[PATCH] uml: move console configuration
This patch changes when console devices are configured in order to prepare the
ground for the next patch.
parse_chan_pair is now done earlier, when initcalls are run, rather than when
the device is opened.
When a host device disappears, the channel list is closed, but not freed.
This is required by the previous change. line_config now takes the options
structure as an argument, and line_open doesn't.
