Description:
In a future MySQL release, we have proposed that skip-innodb will not be supported:
http://www.tocker.ca/2014/05/22/mysql-soon-to-store-system-tables-in-innodb.html

I would like to request that when the server option 'skip-innodb' is specified, mysqld print a warning to the error log saying something like "Option 'skip-innodb' has been removed from MySQL and will not apply."

The rationale is that the behavior change they are requesting is quite small in most cases, and the user can continue to use MyISAM tables.

How to repeat:

Suggested fix:
1) Print warning:
2014-05-14T17:03:31.258417Z 0 [Warning] Option 'skip-innodb' has been removed from MySQL and will not apply.

2) Make sure the server can continue to start.
