Subject: [PATCH] package/connman: improve SysV init script

Use a more generic template for SysV init script, similar to packages
like syslog-ng. This includes adding support for both reload and
restart. Add support for sourcing /etc/default/connmand file, so that
new commandline arguments can be added more easily.
