zstd

Fixed : wrong binary generation by Visual Studio 2013 & 2015 in release mode (issue #52, compiler bug), reported and fixed by Christophe Chevalier (@KrzysFR)

Fixed issues reported by Hanno Böck (@hannob)

• Improved decompression speed (+30%)
• New compressed format
  • Decoder compatible with v0.1.x compressed files

minor improvements :

• Saved one allocation, thanks to @xaphier
• Fixed uninitialization warnings thanks to @nemequ report

Added : frame concatenation support

• fixed a bug in compression
• detects write-on-flush errors

First Zstd release,
compression speed ~ 250 MB/s per core, and decompression speed > 500 MB/s per core.
It features a "robust" decoder, able to properly handle erroneous input.

Note : the internal compressed format is not yet "final".
Use this version for testing only, or if you intend to ship the decoder alongside compressed data.
