There’s no tool doing _all_ that, but there’s the 
Measure_counter_engraver, which goes a long way: 
<http://lilypond.org/doc/v2.19/Documentation/snippets/repeats#repeats-numbering-groups-of-measures>.

\score {
  \new Voice <<
    \repeat percent 4 { c'4 d' e' f' }
    { s1*3 \override Staff.MeasureCounter.count-from = 4 
\startMeasureCount s1 \stopMeasureCount }
  >>
  \layout {
    \context {
      \Staff
      \consists "Measure_counter_engraver"
    }
  }
}

This could be simplified by – guess what: a music function.

Best, Simon
