[Thomas:
 - Remove changelog from the commit log.
 - Rename init script to S99iiod instead of S99iiod.sh
 - Remove "status" command from init script, and implement "restart"
   instead.
 - Add dependency on thread support in toolchain.
 - Fixup indentation in the .mk file.
 - Fixup wrapping in the Config.in help text.]
