ba7a55c321 xl: ReedSolomon code fix small file erasure bug. (#1431) 
For files less than 'dataBlocks', erasure encoding would fail
with short data due to a bug in the implementation itself.

Relax the error return, even a single byte can be properly
erasure coded without issues.

Fixes #1413

This removes odd races since we don't need to

57f35c2bcc xl: Introduce new blocking writer to make CreateFile atomic. (#1362) 
Creates a new write closer that must be released
by the read consumer. This is necessary so that
while commiting the underlying writers in erasure
coding we need to make sure we reply success only if
we have committed to disk.

This in turn also fixes plethora of bugs related to
subsequent PutObject() races with namespace locking.

This patch also enables most of the tests, other than
ListObjects paging which has some issues still.
