> Per core-default.xml {{io.native.lib.available}} indicates "Should native 
> hadoop libraries, if present, be used" however it looks like it only affects 
> zlib. Since we always load the native library this means we may use native 
> libraries even if io.native.lib.available is set to false.
> Let's make the flag to work as advertised - rather than always load the 
> native hadoop library we only attempt to load the library (and report that 
> native is available) if this flag is set. Since io.native.lib.available 
> defaults to true the default behavior should remain unchanged (except that 
> now we wont actually try to load the library if this flag is disabled).
