ensure silo library handles 64 bit integers correctly

Nobody has claimed this yet.

cqid: VisIt00008819cqsubmitter: Mark Millercqsubmitdate: 12/01/08 We need to make sure Silo will handle DB_INTEGER data that is 64 bit integers. More precisely, if sizeof(int) returns 8, we need to make sure Silo will read/write that correctly via HDF5 driver. Also, resole what DB_LONG versus DB_INTEGER means in this context.

cqid: VisIt00008819cqsubmitter: Mark Millercqsubmitdate: 12/01/08 We need to make sure Silo will handle DB_INTEGER data that is 64 bit integers. More precisely, if sizeof(int) returns 8, we need to make sure Silo will read/write that correctly via HDF5 driver. Also, resole what DB_LONG versus DB_INTEGER means in this context.

Comments:

Start by locating Silo's definitions and handling for DB_INTEGER and DB_LONG, then trace the HDF5 driver's integer read/write paths. Determine the intended distinction between the two types and verify behavior when sizeof(int) is 8. Done means 64-bit DB_INTEGER data is read and written correctly through HDF5 with the type semantics documented by the implementation or tests.
