 Add new flag to list inputs and outputs:

 {{{
 r.mapcalc -l "test1 = test2 + test3 + 5"
 input=test2,test3
 output=test1
 }}}

 From #2409:

 {{{
  Such an option would be fairly simple to add. Most of the relevant logic
 is already present in execute() in r.mapcalc/evaluate.c.

 The initialize() function populates the list of input maps (in
 r.mapcalc/map.c or map3.c), which can be used to generate the list of
 inputs. Each top-level assignment expression defines an output.
 }}}
