Krishnan Parthasarathi 285a94d2c0 Ignored errors in cleanup in commitXLMetadata (#2044) 
Deletion of tmp files where xl metadata was saved before the commit
operation doesn't change the error returned to the caller. So, it is to
be ignored.

Krishnan Parthasarathi 64899e5197 xl: Used unique tmp file to update xl.json in putObjectPart (#2043) 
An in-place update to xl.json amidst concurrent PutObjectPart operations
lead to racy updates to xl.json making it un-parseable. To avoid this,
we create a unique tmp file where updates to xl.json are staged before
renaming it to the final location.

Harshavardhana 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

6 disk configuration.

Krishnan Parthasarathi 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.

lesser than 5MB (i.e minimum allowed size per part).

Krishnan Parthasarathi 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.
