Bug#25347: mysqlcheck -A -r doesn't repair table marked as crashed

mysqlcheck tests nullness of the engine type to know whether the
"table" is a view or not.  That also falsely catches tables that 
are severly damaged.

Instead, use SHOW FULL TABLES to test whether a "table" is a view
or not.

(Don't add new function.  Instead, get original data a smarter way.)

Make it safe for use against databases before when views appeared.

Patch by Kasper Dupont.  No CLA required for this size of patch.

"resolveip" program produces incorrect result if given a hostname
starting with a digit.  Someone seems to have thought that names 
can not have digits at the beginning.

Instead, use the resolver library to work out the rules of hostnames, 
as it will undoubtedly be better at it than we are.
