libcsnappy.so is missing a soname

[ppisar]

Every shared library should have a soname for the case when ABI changes and it is necessary to distinguish the incompatible libraries. Otherwise existing executables can start crashing or misbehave.

Please add a soname to the libcsnappy.so library. It's a matter of adding -soname option to the linker and installing proper symlinks to the library. You can also use libtool that helps making the shared library portable.
