rename the DB* classes to:
AbstractDatabase
OracleAdapter
PostgresqlAdapter
SqlserverAdapter

use the non-null function name from db adapter

included new function that returns db specific non-null function name

excluded revisionid from the insert statement for xml_revisions.
It is identity column for SQL Server or filled by sequence for db as Oracle or Postgres

changed like with =

changed ... WHERE ... LIKE ? ...
to ... WHERE ... = ? ...

MS SQL Server stores trailing spaces in varchar fields which shouldn't be
thus added docid.trim() in the Java code

the ODBC multi-threading problem:
in DBQuery we open ResultSet in the db connection and we are trying to
open another Resultset by AccessControlList which does not work
thus open separate connection for use by AccessControlList.

changed
SELECT ... WHERE LIKE ? ...
to:
SELECT ... WHERE = ? ...

It should be changed everywhere it is found

seems that there are problem in JDBC-ODBC bridge used with SQL Server
when using sql statements like:
SELECT ...
WHERE LIKE ? ...
changed to:
SELECT ...
WHERE = ? ...
and now it works
