4bc923e63b XL/fs: Optimize calling isBucketExist() (#1656)
* 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.

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.
