Moving headers used by both server and client to special folder These are the header files which are used by both client and server: src/util/io.h src/util/murmurhash3.h src/util/util_safealign.h This patch is about moving these header files to special folder (src/shared). It will be easier to identify these headers when looking for them in the src tree. util_safalign.h is renamed as safalign.h because util_ namespace is appropriate when this file belonged to the util's folder which is no longer the case.
