MemBuf fix: empty MemBufs are not NULL terminated

This is may cause problems in some cases where the code assume that the MemBuf
is always NULL terminated. For example when an ErrorState object try to use
an empty errorpage template.

This patch terminates the (empty) MemBuf on MemBuf::init method.
