MySQL dialects now query the server version using ``SELECT @@version``
explicitly to the server to ensure we are getting the correct version
information back. Proxy servers like MaxScale interfere with the value
that is passed to the DBAPI's connection.server_version value so this
is no longer reliable.

Repaired regression caused in 1.2.3 and 1.1.16 regarding association proxy
objects, revising the approach to 🎫`4185` when calculating the
"owning class" of an association proxy to default to choosing the current
class if the proxy object is not directly associated with a mapped class,
such as a mixin.

Fixed issue in post_update feature where an UPDATE is emitted
when the parent object has been deleted but the dependent object
is not. This issue has existed for a long time however
since 1.2 now asserts rows matched for post_update, this
was raising an error.

(cherry picked from commit 8607ae51fc)
Fixed regression caused by fix for issue 🎫`4116` affecting versions
1.2.2 as well as 1.1.15, which had the effect of mis-calculation of the
"owning class" of an :class:`.AssociationProxy` as the ``NoneType`` class
in some declarative mixin/inheritance situations as well as if the
association proxy were accessed off of an un-mapped class. The "figure out
the owner" logic has been replaced by an in-depth routine that searches
through the complete mapper hierarchy assigned to the class or subclass to
determine the correct (we hope) match; will not assign the owner if no
match is found. An exception is now raised if the proxy is used
against an un-mapped instance.

(cherry picked from commit 650b9eddae)
Fixed a fairly serious connection pool bug where a connection that is
acquired after being refreshed as a result of a user-defined
:class:`.DisconnectionError` or due to the 1.2-released "pre_ping" feature
would not be correctly reset if the connection were returned to the pool by
weakref cleanup (e.g. the front-facing object is garbage collected); the
weakref would still refer to the previously invalidated DBAPI connection
which would have the reset operation erroneously called upon it instead.
This would lead to stack traces in the logs and a connection being checked
into the pool without being reset, which can cause locking issues.

(cherry picked from commit 5acc9b149a)
Fixed bug where a descriptor that is elsewhere a mapped column
or relationship within a hierarchy based on :class:`.AbstractConcreteBase`
would be referred towards during a refresh operation, causing an error
as the attribute is not mapped as a mapper property.
A similar issue can arise for other attributes like the "type" column
added by :class:`.AbstractConcreteBase` if the class fails to include
"concrete=True" in its mapper, however the check here should also
prevent that scenario from causing a problem.
