Add a dedicated example for `MSSQLServer` compatibility mode, that
shows all DBMS-specific features in a central, user-friendly place.

Add support for `create table test(id int primary key identity)` statements,
which are common in the SQLServer world.

Ignore table hints (e.g. "SELECT * FROM table WITH (NOLOCK)"), that form a
valid expression in SQL Server.

Update Maven build instruction and fix some problems

Upgrade maven-surefire-plugin

The current version has a dependency on an outdated commons-lang version, which throws a NPE when building H2 with Java 11:

Upgrading the `maven-surefire-plugin` fixes this

Throw COLUMN_IS_REFERENCED_1 instead of VIEW_IS_INVALID_2 from DROP COLUMN

Detect ordered result sets in TestScript properly

issue 1350: TestCrashAPI: PageStore.freeListPagesPerList

Fix window functions in queries with HAVING

this looks like some kind of race condition where we are attempting to compact a PageStore which has not been properly opened yet.
Various places in Database are touching the pageStore without being synchronized, so fix those and lets see if that helps

Error handling improvements

Forbid incorrect nesting of aggregates and window functions

Parse GENERATED * AS IDENTITY correctly

Fix subtraction of timestamps

close file/release lock on failures
