Hey Todd,

i am sure that this may be done in a better way, but here we may have the first working patch.
it still include some useless code, and do not cover all of the options, but i wish to get a feedback on this.
code cleanup has to be done.

A brief on the concept:
the new parameter iolog_perm can be set with one octal mode.
Default value is 700, as now.
The allowed range is 700 to 770, as now.
Files will have the exec bit removed for UGO.
Documentation is missing as now.

Next step, if this is more or less ok, is to allow a user and group to be changed in a similar way, plus setting the default group to root.
