presence of the intrinsic routines. Not sure why, but gcc
4.8.5 passes the first but not the second.

ARMv8 defines PMULL crypto instruction.
This patch optimizes crc32c calculate with the instruction when
available rather than original linear crc instructions.
ceph crc32c performance unit test shows that the optimization get

libcephd is a library that contains ceph daemon code
that can be statically linked in other applications.
Added MergeStaticLibraries.cmake that can merge static libraries
to form a bigger one. This approach avoids the need to mess with
STATIC libraries all over the code base.

The used compiler may or may not be recent enough to recognize the
crc32 extended cpu type. However, it does not really have to know about
them either, since all we do is pass inline assembly instructions to
the assembler.
This patch moves the crc cpu extension detection from compiler based
to assembler based, so that we can build optimized code even when the
compiler does not know about the cpu type yet.

Resurrected jerasure_generic, jerasure_sse3, jerasure_sse4, jerasure_neon,
shec_generic, shec_sse3, shec_sse4 and shec_neon. These all are exact
copies of the new jerasure and shec plugins that support SIMD detection.
Moved EC preload code in ceph-mon and ceph-osd to a central location, added
warning when preloading legacy plugins.
OSMonitor::get_erasure_code and OSDMonitor:normalize_profile will now check
if legacy EC plugins are used and log a warning.
Added tests to check that warnings make it to the log.

By switching to a new gf-complete with SIMD runtime detection, we can now remove all the different flavors of jerasure and shec. This simplifies deployment and configuration of erasure coding, enables hetergenous OSDs, and enables us to take advantage of new performance improvements in jerasure without config/build changes.
This commit removes flavors from cmake, removes ErasureCodePluginSelect___, and fixes unit tests. There is now a single plugin for jerasure and a single plugin for shec.
SIMDExt.cmake was changed so that its a little more generic, and is not polluted with gf-complete specific CFLAG defines. The #define for SIMD instruction were based on gf-complete.
I also added a small init helper for jerasure that has code that was common between jerasure and shec.

* renamed target to fio_ceph_objectstore
* moved into src/test/fio subdirectory
* added to cmake build
* added support for DDIR_READ
* added required fio option 'conf' to load a ceph configuration file
* added multiple collections per job to simulate parallelism from pgs
* creates objects of the appropriate size on setup
* added support for multiple jobs that share an ObjectStore instance

* in addition to the -march=foobar, we also need to pass -DFOOBAR to
gf-complete sources' cflags, so that the SIMD instructions can be
generated as expected.
* also extract the compiler support for instruction extensions detections
into SIMDExt.cmake.
* and only check the compiler support if CMAKE_SYSTEM_PROCESSOR matches
with the instruction-set/arch to be checked.

find_package(lttng-ust REQUIRED) fails to find the lttng library without
this change. because find_path(LTTNG_LIBRARY_DIR ...) does not search
in the default library paths. and the second mode of
FIND_PACKAGE_HANDLE_STANDARD_ARGS() does not stop the cmake with a fatal
message, even some of the required vars are missing. so use the
implemetantion from cmake upstream.

* remove Findtcmalloc.cmake, use Findgperftools.cmake instead.
* tcmalloc is packaged in gperftools-dev, so we can check them in a single
place.
* fix the check of heap-profiler.h, we should enable the check as long
as tcmalloc is enabled or profiler is enabled.
* only check gperftools headers in "include/gperftools", and do not
"include/google" anymore. as we only support the distros which
shipping recent gperftools-dev package with "include/gperftools".
and "google/*.h" are deprecated.
* set ALLOC_LIBS with GPERFTOOLS_TCMALLOC_LIBRARY, so we can link
against tcmalloc with full path.
