* xl/ListFiles: return as many objects as requested and take care of eof (#1361)
* xl/ListFiles: fix review comments.
* xl/ListFiles: Add windows filepath translation.
* xl/ListFiles: Use slashSeparator instead of "/". Remove filepath.FromSlash() as golang-windows takes care of it automatically.
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.
Fixes#1358, #1360
