Change brings in a new signVerifyReader which provides a io.Reader
compatible reader, additionally implements Verify() function.
Verify() function validates the signature present in the incoming
request. This approach is choosen to avoid complexities involved
in using io.Pipe().
Thanks to Krishna for his inputs on this.

AppendFile ensures that it appends the entire buffer. Returns
an error otherwise, this patch removes the necessity for the
caller to look for 'n' return on short writes.
Ref #1893
This is necessary for calculating the total storage
capacity from object layer. This value is also needed for
browser UI.
Buckets used to carry this information, this patch
deprecates this feature.
* posix: Avoid using getAllVolumeInfo() in getVolumeDir()
This is necessary compromise to avoid significant slowness this
causes under load. The compromise is also substantial in a way
so that to avoid penalizing common cases v/s special cases.
For buckets with Caps on Unixes, we filter buckets based on the
latest anyways, so this is completely acceptable.
* XL/fs: Change the usage of verification of existance of buckets.
Optimize calling isBucketExists, it is not needed for all call
paths. isBucketExist should be called only for calls which use
temporary volume location for operations, for the rest rely on
the errors returned on their original call path.
Remove usage of filtering as well across all volume names.
- PutObject()
- PutObjectPart()
- NewMultipartUpload()
- AbortMultipartUpload()
Implementations across both FS and XL object layer
share common implementation.
