8a028a9efb handler/PUT: Handle signature verification through a custom reader. (#2066)
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.

d2557bb538 XL: GetObject caching implemented for XL. (#2017)
The object cache implementation is XL cache, which defaults
to 8GB worth of read cache. Currently GetObject() transparently
writes to this cache upon first client read and then subsequently
serves reads from the same cache.

Currently expiration is not implemented.

734e779b19 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
