Bug #27858 Failing to log to a log table doesn't log anything to error log.

Description:
When the server fails to write to the general log table, it doesn't log any errors.
This happens when the log_output is set to file, but it seems all errors happening when logging to a table is silenced.

How to repeat:
See http://bugs.mysql.com/27857 for a way to generate an error that will not be logged.

Suggested fix:
Log with a warning to the error log when an entry can't be written.
In this case maybe you just want to write it once, since every query would probably spam the log to infinity and beyond... but a one-time entry on that we can't enter data to the log would be nice at least.

Thank you for the report.

Verified as described.
