Definitely we have to hide projectid under kernel config option, bu,t
what option should it be? We have two choices
1) CONFIG_QUOTA: because most of users who use quota probably
   will also use project id support
2) introduce new config option: This may be reasonable if projectid
   may be usefull witout quota and inode size is critical.
