XL/Erasure: Make bit-rot verification based on xl.json algo. ( #2299 )
...
Currently `xl.json` saves algorithm information for bit-rot
verification. Since the bit-rot algo's can change in the
future make sure the erasureReadFile doesn't default to
a particular algo. Instead use the checkSumInfo.

XL: fix getBlockInfo() to return correct end block ( #1941 )
...
If requested offset/length of an object is equal to
erasureInfo.BlockSize, getBlockInfo() returns one more block added to
actual end block. This patch fixes the issue.
This patch also adds unit test for get objects with big files.
