The nbcon consoles will have two callbacks to be used for
different contexts. In order to determine if an nbcon console
is usable, console_is_usable() must know if it is a context
that will need to use the optional write_atomic() callback.
Also, nbcon_emit_next_record() must know which callback it
needs to call.
Add an extra parameter @use_atomic to console_is_usable() and
nbcon_emit_next_record() to specify this.
Since so far only the write_atomic() callback exists,
@use_atomic is set to true for all call sites.
For legacy consoles, @use_atomic is not used.
