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
In this case the usage of `StringBuilder` has no additional benefit, since it is not inside a loop where the JVM may have problems detecting String concatenation that can be optimized. The usage of "simple" String concatenation makes the code more readable and the code will be automatically optimised by the compiler.

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.
