object-storage: only open file when requested

Only open a file when the caller of the constructor indicates that it
expects to have a file pointer to access in the "fp" field.

Found by Junaid during review http://review.gluster.org/4284, Patch
set 6.

We also bump the version number to mark a line in the set of changes
we want to perform a mini release with to double check for performance
regressions.
