7d04a0f5e0 Add privileged services

0d7303e75f Parse config later 
This is just to keep the list of open file descriptors tidier, since
parsing the config creates many pipes.

e25813c0b2 Remove closelog call

34c39437f2 Read service pipes 
Changed line reading functions to return const char * because modifying
