Detect leveldb, but do not let autoconf blindly link it with everything on the
planet.

Implement the KeyValueDB interface using libkinetic_client,
and allow it to be configured as the backend for the KeyValueStore,
running the entire OSD on it.
This prototype implementation has no transaction safety, and is
only suitable as a proof of concept. Since the libkinetic_client
API does not provide reverse iteration over keys without also reading
the value off disk, it implements iterators in a very slow but correct way.
These are used heavily by the KeyValueDB callers, so this is a bottleneck
in performance.

Add libkrbd libtool convenience library to provide an interface for
mapping and unmapping rbd images programmatically. This will be used
by the rbd binary itself and the librbd_fsx testing tool.
libkrbd takes care of the kernel module stuff (common/module.h) and
makes use of libudev to be able to properly wait for block device
creation and deletion and tell which block device got assigned by the
kernel to the newly created mapping.

strerror_r is not portable; on Gnu libc it returns char * and sometimes
does not fill in the supplied buffer. Use autoconf to test which
version this platform uses and adapt.
Clean up the random calls to strerror and strerror_r (along with all
their private little one-use buffers) and regularize the code to use
cpp_strerror almost everywhere. Where changed, any negation of the
error code is also removed, since cpp_strerror() will do that.
Note: some tools were using their own calls to strerror/strerror_r, so
will now get a (%d) in their output that wasn't there before; hence
the change to test/cli/monmaptool/print-nonexistent.t
Fixes: #8041

Rename SIMD to INTEL for clarity.
Instead of agregating all flags in INTEL_FLAGS, create individual flags
for each feature (INTEL_SSE2_FLAGS etc.) for finer control in the
makefiles.

For each SSE feature supported by the compiler
* add the corresponding -msse* flag
* define HAVE_SSE*
Remove AX_EXT because it decides based on the CPU capabilities of the
machine compiling the binary which may or may not be the one running
them.

When configured with --without-libxfs, use GenericFileStoreBackend
instead of XfsFileStoreBackend for XFS. At this point this would only
impact the allocation hint op. The default is to compile with
--with-libxfs. (Previously it was unconditionally enabled on linux and
disabled for non-linux arches.)

Introduce XfsFileStoreBackend class, currently the only filestore
backend implementing SETALLOCHINT op. This commit adds a build-time
dependency on libxfs as xfs-specific ioctl (XFS_IOC_FSSETXATTR /
XFS_XFLAG_EXTSIZE) is used to implement the new set_alloc_hint()
method.

Currently CEPH_HAVE_SETPIPE_SZ is not set even if F_SETPIPE_SZ is
available, because AC_COMPILE_IFELSE test program as written always
fails to compile. F_SETPIPE_SZ is a macro, so use AC_EGREP_CPP which
works on the preprocessor output instead of trying to compile.
