Removed variable lstardis in module comdissnew and procedures gradiv
and nxgrarot. lstardir had to be true. gradiv and nxgrarot were called
if lstardis was false. Removed argument iter of procedure
filtreg. iter had to be 1. gradiv and nxgrarot called filtreg with
iter == 2.

Moved procedure flxsetup into module yoecumf. Module yoecumf is only
used in program units of directory Conflx, moved it there.
