Synopsis: file io error on local surestream clips

In the usual case, only one CHXMiniFileObject is created and it accesses
to one IHXMMFDataSource object for reading the local clip. However, in
the case of local surestream clip, multiple CHXMiniFileObject are
created. However, they are currently using the same IHXMMFDataSource
object for file reading, resulting massive clip reading error. Symbian
MMF framework gives Helix only one IHXMMFDataSource object.

This CR proposes a set of read, write, open, seek, and close methods on
IHXMMFDataSource. These new methods enable multiple CHXMiniFileObject
objects to read file though single IHXMMFDataSource object without
interfering each other's reading pointer.
