Fix bug #126952

Now, GFS freezes and unfreezes a filesystem by reading and writing to
/proc/fs/gfs instead of doing ioctl[]s directly on GFS files. This
fixes a bug where a process trying to unfreeze a filesystem would end
up blocking behind another process holding a lock on the mountpoint
and waiting for the filesystem to be unfrozen. This bug has always
been present, but its much more visible in the 2.6 code.

Note that the arguments to "gfs_tool [un]freeze" need to be exactly
whats found in /proc/mounts now.

Also, "gfs_tool margs <mountargs>" replaces the old way of specifying
extra mount arguments: "echo <mountargs> > /proc/fs/gfs".
