XL/erasureCreate: Create a limit reader if size is specified. ( #2059 )
...
This is needed so that we only write data which was requested
for, using a limit reader avoids spurious reads on the incoming
client data. Additionally using limit reader provides server
safety from rogue clients sending copious amounts of data (for
example a denial of service attack).
This patch also caters for size == -1 when content encoding from
a client is set as chunked, we happily read till io.EOF

xl: Used unique tmp file to update xl.json in putObjectPart ( #2043 )
...
An in-place update to xl.json amidst concurrent PutObjectPart operations
lead to racy updates to xl.json making it un-parseable. To avoid this,
we create a unique tmp file where updates to xl.json are staged before
renaming it to the final location.
