lockfile: don't allow multiple instances of daemon to run
until now there is no check to defend on multiple runs of daemon within the same node. This patch takes a non blocking lock on 'gluster-blockd.lock' file, if it succeeds only then daemon is allowed to run, if there is already a lock on lock-file (taken by some other instance of gluster-blockd) we will exit. This patch also renames GB_UNIX_ADDRESS from gluster-block.socket to gluster-blockd.socket, as that makes better sense.
