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.

tests: Use unique name for TEST_PATH We had a cases in patch where two tests were using the same TEST_PATH and therefore they were stepping each other to the same files which caused failures. These failures are not easy to reproduce. This patch uses macro BASE_FILE_STEM for unique name. It should prevent copy&paste problem resulting to intermittent failures. @see also https://www.gnu.org/software/make/manual/html_node/Automatic-Variables.html Reviewed-by: Jakub Hrozek <jhrozek@redhat.com>
