`IsTrue` and `IsFalse` queries no longer use a literal in the query, but a bind parameter.
This allows Spring Data JDBC or the JDBC driver to convert the passed boolean value to whatever is required in the database.
For Oracle converter where added to support storing and loading booleans as NUMBER(1,0) where 0 is false and everything else is true.

Most supported databases don't need that conversion.
Db2 does need it and gets it through JdbcDb2Dialect.
As part of the effort it became obvious that the filtering for conversions between Date and JSR310 data types was broken.
It is fixed now, which required a dedicated reading conversion from LocalDateTime to Date for JdbcMySqlDialect.

Dialects now can define a set of known simple types the driver can handle without further interaction. This is done to avoid warnings during converter registration for types known in one environment but not the other.
Also move types around a bit, change visibility and make sure jdbc specific dialects inherit converters from their parents.

See #935
Dialects may now register a list of converters to take into consideration when reading or writing properties.
See `JdbcSqlServerDialect` for an example.
By default `OffsetDateTime` does not get converted anymore.
If a database needs a conversion it can register it by implementing `Dialect.getConverters()` as described above.

JDBC repository methods now support interface and DTO projections by specifying either the projection type as return type or using generics and providing a Class parameter to query methods.

Fixes copyright dates of new files to the current year.
Fixes the issue reference to use the GitHub notation.
Adds an additional test to ensure that the `ConstantConditionVisitor` doesn't need a predicate.

`JdbcMappingContext` sets the SimpleTypeHolder to `JdbcSimpleTypeHolder.HOLDER` by default.
Fixing test failures where properties of type `UUID` were considered an entity by the `MappingContext`.
This in turn triggered failures when it tried to make fields of `UUID` accessible.
Removed the `UUID` field from a test entity in SD Relational, since `UUID` is not a simple type for Relational, nor a proper entity.
Replaced `@PostConstruct` with `InitializingBean` in test data source conifgurations in order avoid the requirement of importing javax.annotation-api.
Closes#975
Deprecated Spring Data JDBC's custom PersistentProperty.isReference() in favor of the already existing ….isAssociation() with the same semantics to benefit from association definitions implemented in Spring Data Commons. Make use of the newly introduced PersistentEntity.doWithAll(…) to apply the previously existing property handling to both properties and now associations, too.

Removed e-mail from author tag.
Removed spaces from references to methods in KDoc.
Removed superfluous comment.
Corrected copyright date.
Original pull request: #240.
We now support empty IN lists by rendering a condition that evaluates to FALSE using 1 = 0. For NOT IN, we render a condition that evaluates to TRUE using 1 = 1.
