Harshavardhana c0721164be Automatically set goroutines based on shardSize (#5346) 
Update reedsolomon library to enable feature to automatically
set number of go-routines based on the input shard size,
since shard size is sort of a constant in Minio for
objects > 10MiB (default blocksize)

klauspost reported around 15-20% improvement in performance
numbers on older systems such as AVX and SSE3

Andreas Auernhammer 85fcee1919 erasure: simplify XL backend operations (#4649) (#4758) 
This change provides new implementations of the XL backend operations:
 - create file
 - read   file
 - heal   file
Further this change adds table based tests for all three operations.

This affects also the bitrot algorithm integration. Algorithms are now
integrated in an idiomatic way (like crypto.Hash).
Fixes #4696
Fixes #4649
Fixes #4359

Anis Elleuch af8071c86a xl: Fix rare freeze after many disk/network errors (#4438) 
xl.storageDisks is sometimes passed to some low-level XL functions. Some disks in
xl.storageDisks are set to nil when they encounter some errors. This means all
elements in xl.storageDisks will be nil after some time which lead to an unusable XL.
