\set Staff.barAlways = ##t
\set Staff.defaultBarType = ""

This sets a "" barline after every rhythmical event that occurs in the 
score (not only the current staff). You then need to set the “real” 
barlines by hand, something like:

\new Staff <<
  { \time 3/2 c''1 2 1 2 }
  \repeat unfold 2 { s1. \bar "|" }
>>

Hm … the solution from above breaks beaming because autobeaming never 
sets beams across barlines.

The code above just inserts "" barlines; to allow breaking in the middle 
of sounding notes you’ll need

\remove Forbid_line_break_engraver

in the Voice context(s).
