* Fixed the warnings for ZStandardDecompressor.c
* Updated the Building.txt
* Used the constant IO_COMPRESSION_CODEC_ZSTD_LEVEL_DEFAULT and fixed the
default compression level
* Sorted out the TODO for the compression overhead.
[~jlowe] what do you think about adding a test that would go through all the
codecs and run the M/R job you used as your example with the MRMiniCluster, do
you think that would be worthwhile?
