Update build system and packaging

Minimal changes required to integrate the SPL sources in to the
ZFS repository build infrastructure and packaging.

Build system and packaging:
  * Renamed SPL_* autoconf m4 macros to ZFS_*.
  * Removed redundant SPL_* autoconf m4 macros.
  * Updated the RPM spec files to remove SPL package dependency.
  * The zfs package obsoletes the spl package, and the zfs-kmod
    package obsoletes the spl-kmod package.
  * The zfs-kmod-devel* packages were updated to add compatibility
    symlinks under /usr/src/spl-x.y.z until all dependent packages
    can be updated.  They will be removed in a future release.
  * Updated copy-builtin script for in-kernel builds.
  * Updated DKMS package to include the spl.ko.
  * Updated stale AUTHORS file to include all contributors.
  * Updated stale COPYRIGHT and included the SPL as an exception.
  * Renamed README.markdown to README.md
  * Renamed OPENSOLARIS.LICENSE to LICENSE.
  * Renamed DISCLAIMER to NOTICE.

Required code changes:
  * Removed redundant HAVE_SPL macro.
  * Removed _BOOT from nvpairs since it doesn't apply for Linux.
  * Initial header cleanup (removal of empty headers, refactoring).
  * Remove SPL repository clone/build from zimport.sh.
  * Use of DEFINE_RATELIMIT_STATE and DEFINE_SPINLOCK removed due
    to build issues when forcing C99 compilation.
  * Replaced legacy ACCESS_ONCE with READ_ONCE.
  * Include needed headers for `current` and `EXPORT_SYMBOL`.

-Brian Behlendorf is the principal developer of the ZFS on Linux port.
-He works full time as a computer scientist at Lawrence Livermore
-National Laboratory on the ZFS and Lustre filesystems.  However,
-this port would not have been possible without the help of many
-others who have contributed their time, effort, and insight.

-First and foremost the hard working ZFS developers at Sun/Oracle.
-They are responsible for the bulk of the code in this project and
-without their efforts there never would have been a ZFS filesystem.
+PAST MAINTAINERS:
 
-  The ZFS Development Team at Sun/Oracle
+    Ned Bass <[email protected]>
 
-Next all the developers at KQ Infotech who implemented a prototype
-ZFS Posix Layer (ZPL).  Their implementation provided an excellent
-reference for adding the ZPL functionality.
