dlls/oledb32: added conversions for I1, I8, UI2, DEC and GetConversionSize

[Andreas Pflug]

This complements my previous post, which is included for completeness' 
sake below (0001-OLEDB-xxx)

convert_DataConvert is extended for the types DBTYPE_I1, DBTYPE_I8 
,DBTYPE_UI2, DBTYPE_DECIMAL. The conversions are performed using the 
OLEAUT32-Functions VarXXXFromYYY, as far as they exist which made this 
mostly a carefully handled copy/paste job.

Conversion DBTYPE_TIMESTAMP<->DBTYPE_DATE have been successfully tested 
using a commercial app (HIW Rendite 10).

GetConversionLength has been implemented trivially for fixed-length 
dstTypes, and partially for var-length types (as far as the app required 
it).

convert_DataConvert now know the types DBTYPE_R8, DBTYPE_BOOL,
DBTYPE_DATE and will convert from all source types supported by
VarXXXFromYYY functions.
DBTYPE_TIMESTAMP is supported to convert from and to DBTYPE_DATE.
get_length is extended accordingly.
