Hi, I have created another patch to fix some memory leaks, close files and do
cleanups. It contains:

- free() and close() where needed;
- defConfig setup moved from logrotate.c to config.c;
- pointers of compression options are set only by allocated strings, so I could
include them in free_logInfo(), to free() properly when someone set them by
configuration file;
- new function createOutputFile(), which contains code that was duplicated in
three functions of logrotate.c;
- other minor things, let's see if this time I didn't break something.

One note:

      - In copyTruncate() (logrotate.c), I have changed the creation of output
file to use the new function createOutputFile(), but before the open() function
was between two blocks of SELINUX code and the fchmod/fchown functions were
after the second block. Now the fchmod/fchown() functions are inside the
function createOutputFile, which I put between the two blocks of SELINUX, as the
open() function was localized. I don't know how SELINUX work, so I need help
from someone to tell if this change can be a problem.
