[OPENJPA-3033] Store char fields as CHAR(1) on Derby, H2 and SQL Server (#245)
* [OPENJPA-3033] Store char fields as CHAR(1) on Derby and SQL Server
DerbyDictionary and SQLServerDictionary used the DBDictionary default
StoreCharsAsNumbers=true, so a char was written as its code point. On a
CHAR(1) column such as the one in the Jakarta Persistence TCK schema, Derby
failed the insert with 22001 ('97' does not fit) and SQL Server failed to
read '*' as an INTEGER. Both now default to native CHAR storage, like DB2,
MySQL and PostgreSQL 9+; an explicit StoreCharsAsNumbers=true still selects
numeric columns.
A generated CHAR column for a char/Character field without an explicit
length is now CHAR(1) instead of CHAR(CharacterColumnSize), which Derby
rejected as CHAR(255).
* [OPENJPA-3033] Store char fields as CHAR(1) on H2 too

> These tests fail on Derby and only report "failed", the cause has to be found
> from the TCK logs:
> * {{fieldTypeTest1}} to {{fieldTypeTest17}}, {{propertyTypeTest1}} to
> {{propertyTypeTest13}} (field and property access)
> * {{autoTypeTest1}} to {{autoTypeTest6}}, {{generatorTypeTest1}} to
> {{generatorTypeTest6}}, {{generatorTypeSequenceTest}}
> * {{persistBasicTest2}} to {{persistBasicTest5}}
> * {{Client2}} / {{Client5}}: {{BigDecimal}}, {{BigInteger}}, {{Double}},
> {{Float}}, {{Long}} and {{ShortOperandResultTypeTests}}
> * {{dateTimeTest}} (Java 8 date and time types)
> {{propertyTypeTest1}} and {{autoTypeTest1}} also fail on SQL Server.
