Implement replacement functions for executing commands

This commit implements replacement functions for the previous
exec functions.
The replacements are implemented in a more "pure" style, the do no
longer receive pointer arguments which they will write to, but create
the pointers themselves and should therefore be easier to use,
since it is more obvious what goes in and what comes out.

Also a essentialy unused variable was removed with this.
