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

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
