5b1bc1a1d8 Set proper dependency for string replacement targets
A lot of string replacement target don't have dependency or incorrect
dependency. We setup proper dependency by pattern rules.

92547bc45c Systemd configuration fixes
* Disable zfs-import-scan.service by default.  This ensures that
pools will not be automatically imported unless they appear in
the cache file.  When this service is explicitly enabled pools
will be imported with the "cachefile=none" property set.  This
prevents the creation of, or update to, an existing cache file.

    $ systemctl list-unit-files | grep zfs
    zfs-import-cache.service                  enabled
    zfs-import-scan.service                   disabled
    zfs-mount.service                         enabled
    zfs-share.service                         enabled
    zfs-zed.service                           enabled
    zfs.target                                enabled

* Change services to dynamic from static by adding an [Install]
section and adding 'WantedBy' tags in favor of 'Requires' tags.
This allows for easier customization of the boot behavior.

* Start the zfs-import-cache.service after the root pivot so
the cache file is available in the standard location.

* Start the zfs-mount.service after the systemd-remount-fs.service
to ensure the root fs is writeable and the ZFS filesystems can
create their mount points.

* Change the default behavior to only load the ZFS kernel modules
in zfs-import-*.service or when blkid(8) detects a pool.  Users
who wish to unconditionally load the kernel modules must uncomment
the list of modules in /lib/modules-load.d/zfs.conf.

47a4a6fd5f Support parallel build trees (VPATH builds)
Build products from an out of tree build should be written
relative to the build directory.  Sources should be referred
to by their locations in the source directory.

This is accomplished by adding the 'src' and 'obj' variables
for the module Makefile.am, using relative paths to reference
source files, and by setting VPATH when source files are not
co-located with the Makefile.  This enables the following:

  $ mkdir build
  $ cd build
  $ ../configure \
    --with-spl=$HOME/src/git/spl/ \
    --with-spl-obj=$HOME/src/git/spl/build
  $ make -s

This change also has the advantage of resolving the following
warning which is generated by modern versions of automake.

  Makefile.am:00: warning: source file 'xxx' is in a subdirectory,
  Makefile.am:00: but option 'subdir-objects' is disabled

881f45c6a8 Add systemd unit files for ZFS startup
This adds systemd unit files replacing the functionality offered by
the SysV init script found in etc/init.d.

It has been developed and tested on Fedora 19, Fedora 20
and openSuSE 13.1.

Four unit files and one target are offered.

zfs-import-cache.service:
    Import pools from /etc/zfs/zpool.cache. This unit will wait for
    udev to settle.
zfs-import-scan.service:
    Import pools by scanning /dev/disk/by-id for zvols. This unit will
    only run if /etc/zfs/zpool.cache is not present. This unit will wait
    for udev to settle
zfs-mount.service:
    Mount ZFS native filesystems. It contains a dependency to be loaded
    before local-fs.target.
zfs-share.service:
    Share NFS/SMB filesystems. This unit contains a dependency that
    will cause it to be restarted whenever the smb or nfs-server unit
    is restarted, restoring the shares added.
zfs.target:
    This target pulls in the other units in order to start ZFS. It's
    the only unit that can be enabled/disabled, all other services
    are static and pulled in by dependencies. It will honour zfs=off
    and zfs=no options on the kernel command line.
