Changed default behaviour to an empty name for embedded entities.
This allows to use embedded entities for column tuples without special prefix.
Original pull request #1149
Table alias for embedded entity use prefix value from Embedded annotation. But default value for prefix is empty string. If try to create SqlIdentifier for empty string it throw exception. To avoid this behavior, if prefix is an empty string, property name for embedded entity is taken instead.
This change extracts entity modifying behaviour into separate methods, so it doesn't appear as an unexpected side effect of the creation of aggregate changes.
Also some formatting.

Insert for entities of same type within an aggregate get inserted using JDBC batch operations when possible.
Inserts are supported when no id needs to be generated by the database or if the Dialect supports generation of ids in batch operations.

Added the missing functionality that is found in the documentation of spring-data-jdbc, but was not present in the code as functionality. Users can not choose between various QueryLookupStrategies.

We now associate a boolean value with both operators as those operators are rendered using equals comparison in the actual SQL text.

This allows both Spring Data R2DBC and Spring Data JDBC to use the same annotation.
See spring-projects/spring-data-jdbc/issues/1041, spring-projects/spring-data-r2dbc/pull/720, spring-projects/spring-data-jdbc/pull/1158
Refactored the unit tests to include a negative case and to separate the different scenarios tested.
Removed the default LockMode from the Lock annotation.
I have the feeling that most users will assume an exclusive Lock when none is specified, but also don't want to request stronger locks than required.

Methods which use the derive query functionality now can be annotated with `@Lock` to used a given `LockMode`. Right now there are two different modes `PESSIMISTIC_READ` and `PESSIMISTIC_WRITE`. Based on the dialect the right select is generated. For example for HSQLDB `Select ... FOR UPDATE`.

Rename "null handling" to "null precedence".
This is somewhat inconsistent with commons null handling, but more descriptive.
Minor formatting.

java.sql.Types constants are int values and therefore make it tedious to read and debug the code.
SQLType values are mostly enum constants which are much nicer to use.

This is achieved by passing the full availabe type information of the conversion target to the conversion service.
This broke a test which wasn't functional in the first place which becomes obvious when adding the proper assertion.

Original pull request #1144
With older versions H2 returned a proprietary instance of `TimestampWithTimeZone` from `ResultSet.getObject()`.
We used to support the conversion of that to an `OffsetDateTime`.
With the most recent versions `TimestampWithTimeZone` is no longer part of the H2 driver, and we only register the converter when we encounter older versions of H2.

Simplified the code structure.
Ensured backward compatibility by recreating some methods often immediately deprecating them.
Moved new classes to the places where they belong, so that the package ...core.sql.render depends on ...core.dialect and not the other way round.
This causes dependency cycles because dependencies in the other direction already exists.
This will be properly fixed by #1105.
For now the offending classes are ignored by the DependencyTests.
