The Snappy Java Jar is not compatible with Apache Felix 4.2.1 Framework

The Snappy Bundle contains the Bundle-NativeCode instruction in a way it's not compatible with the [R4LibraryClause](http://svn.apache.org/viewvc/felix/releases/org.apache.felix.framework-4.2.1/src/main/java/org/apache/felix/framework/util/manifestparser/R4LibraryClause.java?view=markup) because the osname and processor definition is mandatory. They can not be replaced with selection-filter.

Snappy 1.0.5 and the 1.1.0-SNAPSHOT throws the same org.osgi.framework.BundleException: Unresolved constraint in bundle org.xerial.snappy.snappy-java [n]: No matching native libraries found. exception.

I saw in the fixed issues the Snappy was tested on Eclipse 3.8.1 but I couldn't tested so it has to be verified. I also updated the x86-64 from x86_64 regarding the [Bundle-NativeCode: OS/Processor values](http://www.osgi.org/Specifications/Reference)
