MINOR: stats: introduce stats_dump_one_line() to dump one stats line

This new function dumps the current stats line according to the
specified format (CSV or HTML for now), and returns these functions'
output code, which will serve later to indicate a failure (eg: buffer
full).

This further simplifies the code since all dumpers now just call this
function.
