Currently the helper must somehow guess how many import statements to
read before it starts outputting its fast-export stream. This is
because the remote helper infrastructure runs fast-import only once,
so the helper is forced to output one stream for all import commands
it will receive. The only reason this worked in the past was because
only one ref was imported at a time.
Change the semantics of the import statement such that it matches
that of the list statement. That is, 'import\n' is followed by a list
of refs that should be exported, followed by '\n'.

his series.
