compatibility of the RPMs
 - added "restart" action to the mysql.server init script


support-files/mysql.server.sh:
   - added "restart" action
support-files/mysql.spec.sh:
   - moved init script from /etc/rc.d/init.d to /etc/init.d (the majority of 
     Linux distributions now support this scheme as proposed by the LSB either
     directly or via a compatibility symlink)
   - relaxed the Perl requirements a bit
   - Use new "restart" init script action instead of starting and stopping
     separately
   - Be more flexible in activating the automatic bootup - use insserv (on
     older SuSE versions) or chkconfig (Red Hat, newer SuSE versions and
     others) to create the respective symlinks
