Wait for post:script and cleanup:script before returning OK

Browse Source 
This change introduces two new states for the big Finit state machine:
runlevel-clean and reload-clean.  Here Finit now waits for any post or
cleanup script to finish before returning OK to the initctl command.

Additionally, the service state machine has been updated to ensure a
run/task/sysv/service calls any post or cleanup script before they are
removed.  A new 'dead' state for svc_t is introduced which any removed
svc_t ends up in now instead of becing collected from 'halted' state.
