Bug #75954 Outdated info about SQL standards

Description:
http://dev.mysql.com/doc/refman/5.7/en/compatibility.html

"“SQL:2008” refers to the most recent version of the standard, released in 2008"

That's not true anymore as SQL:2011 is currently the most recent standard.

SQL:2011 is also known as "ISO/IEC 9075:2011"

http://www.iso.org/iso/iso_catalogue/catalogue_tc/catalogue_detail.htm?csnumber=53681

http://standards.iso.org/ittf/PubliclyAvailableStandards/index.html

How to repeat:
Read docs and compare with ISO standards.

Suggested fix:
Update docs with compliance status to SQL:2011

This is actually quite true and even we , on this channel, extensively make references to SQL:2011 standard.

Verified.

Note that SQL-92 seems to have different levels of compliance. Which one does MySQL support?

I've added SQL:2011 to the list of SQL standards.

In some cases the standards used during development were explicit and are noted.
For example, see "Additional Resources" at:
