Added BPositionIO::GetSize() and implemented it by means of Seek() and

Browse Source 
Position(). This used up a virtual slot of BPositionIO. GetSize() needed to be
implemented in BFile, which uses the BStatable version as before. This should

compatibility when there are classes inheriting from BPositionIO implementing
their own GetSize().
