Subject: [PATCH] Rename all uses of ivar eof_position. ([MemoryStream
 -_initOnMallocBuffer:freeWhenDone:size: eofPosition:prefix:position:]):
 Method name changed to include freeWhenDone:.  Set new ivar. ([MemoryStream
 -_initOnMallocBuffer:size: eofPosition:prefix:position:]): New method (with
 old name) that calls above method with `YES' for freeWhenDone:.
