Description:
There are two parts to this bug:

1. the thread that processes COM_SHUTDOWN logs something to general log and nothing to mysqld log file. It should log there as much information about the client issuing the shutdown as it can.

2. the signal processing thread logs nothing. It can't log much either because it uses sigwait(). It should use sigwaitinfo() and log all known data about the signal issuer.

How to repeat:
see code

Fixed in 8.0.12.

When a client shuts down the server, the server now writes a message
to the error log indicating which user performed this action.
