Description:
In errmsg.txt:

ER_COL_COUNT_DOESNT_MATCH_CORRUPTED
        eng "Column count of mysql.%s is wrong. Expected %d, found %d. The table is probably corrupted"

ER_CANNOT_LOAD_FROM_TABLE
        eng "Cannot load from mysql.%s. The table is probably corrupted"

The table schema is hard coded to mysql.

This is wrong, the table schema should be a %s argument in the error message,
so that the error message itself could be used for information_schema, performance_schema, etc.

Currently, table_check_intact() in table.cc get a fully qualified table schema
+ table name, but raise wrong messages like:
Column count of mysql.FILE_SUMMARY_BY_EVENT_NAME is wrong. Expected ...
instead of
Column count of perfschema.FILE_SUMMARY_BY_EVENT_NAME is wrong. Expected ...
because the table schema is hard coded to mysql in the error message.

How to repeat:
read errmsg.txt, read table.cc

Suggested fix:
%s in the message text

Noted in 6.0.14 changelog.

Some error messages included a literal mysql database name rather
than a parameter for the database name.
