New queries hang when a client connection is closed after the 100 ms period of inactivity

. fix unixSocket connection for mariadb

Fix CustomEventEmitter

Make sure that objects passed to CustomEventEmitter's `error` event
are boiled down to real Error instances so that node's EventEmitter
does not give us this nasty "Uncaught, unspecified error" thing.

Fix CustomEventEmitter error handling

Override .emit() to first check whether the error argument is an array. In case
it is an array, reduce it to the very first error and pass it to the original
EventEmitter.emit()

Sequelize.ENUM: Values as arguments / array

Added tests for both field: Sequelize.ENUM and field: { type: Sequelize.ENUM }

Fix for #1234 - Postgres query should set on .dataValues instead of object

Validation skipping logic was inverted. Fixed #1169

… last one (right when the client connection is closing)
Also added a possible fix

better check if 'IS NOT' or '!=' should be used
