Bug fixed: Column charset were not handled on read. 

Modified: ha_connect.cc (MakeRecord)

Moved PlgAllocResult to plgdbutl.cpp
Modified:
mycat.cpp
plgdbutl.cpp

Continuing implementing the "catalog" tables (ex "info").
Already existing were the ODBC data source table and the
WMI column info table.

The common way to handle them was modified to enable each
table types to send personalized data.

Now takes care of all existing catalog functions for table
types that can retrieve and use such information.
