WL#1032: Merge init.d mysql and mysqld_multi

Affects: Server-7.1   —   Status: On-Hold   —   Priority: Medium

Put this on hold, we are looking at having an instance manager in 5.0 which
would remove the need for either of these files. 

For a user  on a UNIX system to have easy support of multiple instance of the
mysql server they must copy the mysqld_multi script from its installed location
and place it in /etc/init.d (aka overwrite the init.d default version). The
problem is that the next time you do an RPM install it will overwrite
mysqld_multi and reinsert the original initd script. 
What needs to happen is that the init.d script and the multi script need to be
merged. This way support of multiple masters is automatic.
