Build system and packaging (RPM support) (Part 1)

    An update to the build system to properly support all commonly
    used Makefile targets these include:

      make all        # Build everything
      make install    # Install everything
      make clean      # Clean up build products
      make distclean  # Clean up everything
      make dist       # Create package tarball
      make srpm       # Create package source RPM
      make rpm        # Create package binary RPMs
      make tags       # Create ctags and etags for everything

    Extra care was taken to ensure that the source RPMs are fully
    rebuildable against Fedora/RHEL/Chaos kernels.  To build binary
    RPMs from the source RPM for your system simply run:

      rpmbuild --rebuild zfs-x.y.z-1.src.rpm

    This will produce two binary RPMs with correct 'requires'
    dependencies for your kernel.  One will contain all zfs modules
    and support utilities, the other is a devel package for compiling
    additional kernel modules which are dependant on the zfs.

      zfs-x.y.z-1_<kernel version>.x86_64.rpm
      zfs-devel-x.y.2-1_<kernel version>.x86_64.rpm
