Harshavardhana 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.

Krishnan Parthasarathi 596fe65e84 Write pprof output files under config dir supplied (#1660) 
Since config dir, supplied as command line argument, is parsed after pprof
output directory is determined, pprof output files are  written in ~/.minio/profile
directory instead of <configDir>/profile/. This change fixes this behaviour.

Harshavardhana 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.

Bala FA adbcafefad xl/CreateFile: handle errFileNameTooLong error properly (#1523)

Harshavardhana 86e5d71519 erasure: MakeVol, DeleteVol and StatVol should hold locks. (#1597) 
Since there is a good amount of overlap, each code has to lock
properly for the operation they are going to perform.

- MakeVol create vols in a routine on all disks, hold locks.
- DeleteVol delete vols in a routine on all disks, hold locks.
- StatVol stat vols in a routine on all disks, hold locks.

Harshavardhana 72748d2073 erasure: healVolume err should be different from shadowed version. (#1590) 
Multiple go-routines updating the same shadowed variable can

Harshavardhana 49141eb3e4 http: Remove minhttp package and use standard Golang http. (#1587) 
The functionality provided by minhttp will be implemented
cleanly through our own APIs. Since we are not going to
send SIGUSR2 and manage configuration in that manner, it
doesn't make sense to use minhttp.
