3ac39ff107 XL: Change minimum disks supported to 6 now. (#2023) 
This change co-incides with another patch set which
reduces the writeQuorum requirement. With the
write quorum change it is now possible to support
6 disk configuration.

b6b9e88e47 Added unit-tests for treeWalkPool (#1969) 
* Added unit-tests for treeWalkPool
* Added unit tests for tree-walk-fs
* Added period at the end of all comments.
* FS/XL: Unified tree walk tests for both backends
* Added disk failure related tests for treewalk

Replaced removeRandomDisks with removeDiskN. There is no need to
randomize disks that fail while the distribution of chunks in XL during
erasure coding data is random.

748dc80047 API: add writePartTooSmallErrorResponse to extend standard error responses. (#2005) 
This function is added to extend the standard error responses.
Which is needed in some cases for example CompleteMultipartUpload
should respond with ErrPartTooSmall error when parts uploaded are
lesser than 5MB (i.e minimum allowed size per part).

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.

7d757033f2 erasure-readfile: Use chunk size to read from each disk for a block. (#1949) 
A block of data is split into data chunk and each data chunk is
written to each disk.  Previously block size was used to read data
chunk which returns corrupted data.

This patch fixes the issue by reading chunk sized data from each disk
and assembles a block.
