Fixed error number handling bug in mysqltest.
Fixed that error number from insert delayed is reported correctly.
merged new vio code with old violite code.
Added preliminary handling of symlinks in MyISAM.
When using myisamchk to check tables with --force, don't repair
tables that are marked as 'not closed' if they are ok.
Change fn_format() to use my_real_path and my_symlink
