DEPRECATED

Before this fix,
  SELECT @@GLOBAL.SQL_LOG_BIN
did produce a deprecation warning, as expected.

However,
  SELECT * FROM INFORMATION_SCHEMA.GLOBAL_VARIABLES
also produced a deprecation warning about SQL_LOG_BIN.
This warning is causing confusion, and is not desirable.

With this fix,
  SELECT * FROM INFORMATION_SCHEMA.GLOBAL_VARIABLES
does not produce any warnings caused by the
deprecation of system variables.
