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.

d0be09fdd3 object: checkETag compares quoted ETags properly (#1997) 
Previously, checkETag didn't handle ETags with leading and trailing
double quotes. e.g "abcdef1234" == "\"abcdef1234\"" would return false.
Now, checkETag function canonicalizes the ETags passed as arguments by
removing one leading/trailing double quote.

9472299308 logging: Log only for unhandled errors, remove all the debug logging. (#1652) 
This patch brings in the removal of debug logging altogether, instead
we bring in the functionality of being able to trace the errors properly
pointing back to the origination of the problem.

To enable tracing you need to enable "MINIO_TRACE" set to "1" or "true"
environment variable which would print back traces whenever there is an
error which is unhandled or at the handler layer.

By default this tracing is turned off and only user level logging is
provided.
