There is a lot of good stuff going on here, but nobody is investing in xio
and it is not expected to be the path forward for RDMA. If that ever
changes, we can resurrect the code. Until then, let's clean up the tree
and reduce friction for changes going forward.

rabbitmq-c is not a header-only library. so we need to ensure that the
library is also around before linking against it. in this change:
* move the detection down to where librabbitmq is used
* add FindRabbitMQ.cmake for find_package(RabbitMQ)
* s/rabbitmq/RabbitMQ::RabbitMQ/ as the latter is an alias library
target, which has more information attached to it.

We can re-enable after we branch. For N, though, there is no point in dragging

This patch introduces new FIO engine which main goal is to test
bare Ceph messenger transport layer performance. Engine submits
requests in async manner and polls for completion. Completions
are kept in lockless ring buffer so on hot path no muteces or
conditions are used in order to get maximum bandwidth and less
latency.

It is rather had to overide a once set timeout during CTesting.
This is the best next compromise. Disadvantage is that a rebuild
is required.
But it helps in my Jenkins testing timely catching run-away programs.

Ceph requires C++17 support from compiler. This means gcc 7.x being
minimal version supported.
This also allows to fail quick on Debian 'stretch' with it's gcc 6.3
compiler.

If CEPH_DEBUG_MUTEX is defined, use the [recursive_]mutex_debug classes
that implement lockdep and a bucnh of other random debug checks. Also
typedef ceph::condition_variable to std::condition_variable_debug, which
adds addition assertions and debug checks.
If CEPH_DEBUG_MUTEX is not defined, then use the bare-bones C++ std::mutex
primitives... or as close as we can get to them.
Since the [recursive_]mutex_debug classes take a string argument for the
lockdep piece, define factory functions ceph::make_[recursive_]mutex that
either pass arguments to the debug implementations or toss them out.

by default, debian packaging creates ${prefix}/lib/x86_64-linux-gnu for

FindBoost.cmake from upstream cmake now finds python libraries like
find_package(Boost 1.67 python36)
and it export targets like Boost::python36
but we are still linking against Boost::python, so to be compatible
with FindBoost.cmake, we need to update BuildBoost.cmake and
mgr/CMakeLists.txt accordingly. in other words, to export
Boost::python36 and to link Boost::python36.

as the higher version of libstdc++ is backward compatible with the lower
ones. so there is no need to statically link against C++ libraries. they
can always use the libstdc++ ships with the distro.

also, we don't need to pass '-lasan' or '-ltsan' to linker. it's
suggested to use the "-fsanitize=${sanitizer}".
please note, this module is compatible with the one used in seastar on
purpose, as seastar is included in ceph using add_subdirectory(), and it
in turn add its own cmake modules directory using list(APPEND ...), so
cmake/modules/FindSantitizers.cmake is prefered over
src/seastar/cmake/FindSantitizers.cmake.

we could create a mini project to build a shared library, and use
try_compile() to test if the found gperftools is compiled with -fPIC.
but as we are targeting mostly xenial when enabling
WITH_STATIC_LIBSTDCXX, and google-perftools on xenial by default
is built without -fPIC. so let's keep it simple.

do not build ceph_test_admin_socket_output if we are not able to find
the library for std::experimental::filesystem . it is a workaround of
https://reviews.freebsd.org/D10840 where FreeBSD 11.2 does not ship

- do not link libkv with ALLOC_LIBS, it turns out that if we link
tcmalloc *before* -static-libstdc++ -static-libgcc, libstdc++ and gcc
libs will show up in `ldd` output
- add `-static-libstdc++ -static-libgcc` to CMAKE_SHARED_LINKER_FLAGS
and CMAKE_EXE_LINKER_FLAGS instead of adding them to all shared
libraries and executable. simpler this way.
- link against libtcmalloc statically, because libtcmalloc is a C++
library, linking against it dynamically and linking against C++ runtime
statically will pull in depdencies on two versions of C++ runtime, which
will bring down the app at run-time.
- do not pass '-pie' to linker when building executable if
`WITH_STATIC_LIBSTDCXX` and tcmalloc is used, because the static tcmalloc
is not compiled with PIC.
- only apply '-pie' if ENABLE_SHARED is enabled.
