Move platform specific Linux source under module/os/linux/
and update the build system accordingly. Additional code
restructuring will follow to make the common code fully
portable.

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`.

Currently, when ZFS wants to accelerate compression with QAT, it
passes a destination buffer of the same size as the source buffer.
Unfortunately, if the data is incompressible, QAT can actually
"compress" the data to be larger than the source buffer. When this
happens, the QAT driver will return a FAILED error code and print
warnings to dmesg. This patch fixes these issues by providing the
QAT driver with an additional buffer to work with so that even
completely incompressible source data will not cause an overflow.
This patch also resolves an error handling issue where
incompressible data attempts compression twice: once by QAT and
once in software. To fix this issue, a new (and fake) error code
CPA_STATUS_INOMPRESSIBLE has been added so that the calling code
can correctly account for the difference between a hardware
failure and data that simply cannot be compressed.

This patch implement the hardware accelerator method in GZIP compression
in ZFS. When the ZFS pool is enabled GZIP compression, the compression
API will be automatically transferred to the hardware accelerator to
free up CPU resource and speed up the compression time.
* To enable Intel QAT hardware acceleration in ZOL you need to have QAT
hardware and the driver installed:
* QAT hardware DH8950:
http://ark.intel.com/products/79483/Intel-QuickAssist-Adapter-8950
* QAT driver:
https://01.org/intel-quickassist-technology
* Start QAT driver in your system:
service qat_service start
* Enable QAT in ZFS, e.g.:
./configure --with-qat=<qat-driver-path>/QAT1.6
make
* Set GZIP compression in ZFS dataset:
zfs set compression = gzip <dataset>
* Get QAT hardware statistics by:
cat /proc/spl/kstat/zfs/qat
* To disable QAT in ZFS:
insmod zfs.ko zfs_qat_disable=1

Enable picky cstyle checks and resolve the new warnings. The vast
majority of the changes needed were to handle minor issues with
whitespace formatting. This patch contains no functional changes.
Non-whitespace changes are as follows:
* 8 times ; to { } in for/while loop
* fix missing ; in cmd/zed/agents/zfs_diagnosis.c
* comment (confim -> confirm)
* change endline , to ; in cmd/zpool/zpool_main.c
* a number of /* BEGIN CSTYLED */ /* END CSTYLED */ blocks
* /* CSTYLED */ markers
* change == 0 to !
* ulong to unsigned long in module/zfs/dsl_scan.c
* rearrangement of module_param lines in module/zfs/metaslab.c
* add { } block around statement after for_each_online_node

The vast majority of these changes are in Linux specific code.
They are the result of not having an automated style checker to
validate the code when it was originally written. Others were
caused when the common code was slightly adjusted for Linux.
This patch contains no functional changes. It only refreshes
the code to conform to style guide.
Everyone submitting patches for inclusion upstream should now
run 'make checkstyle' and resolve any warning prior to opening
a pull request. The automated builders have been updated to
fail a build if when 'make checkstyle' detects an issue.

Do not use zmod.h in userspace.
This has also been filed with the ZFS team. It makes the userspace
libzpool code use the zlib API, instead of the Solaris-only and
non-standard zmod.h. The zlib API is almost identical and is a de
facto standard, so this is a no-brainer.
