add_custom_target cannot create target "foo-clone" because another
target with the same name already exists.

use the ones shiped from the latest cmake. which
* enables us to find the recent python intepreter and development files,
* find intepreter and development in a single `find_pacakge()` command,
simpler this way and less error prone.
and to accomodate this change:
* all `PYTHON${PYTHON_VERSION}_*` variables are renamed to
`Python${PYTHON_VERSION}_*` if we use `find_package(Python2...)` or
`find_package(Python3...)` to find python2 or python3 instead of using
`find_package(Python...)`.
* use "2" explicitly when using python2, as `Python_*` variables are not
defined anymore
* when compiling python support of ceph-mgr, continue using `Python_*`
variables. because we find the python interpreter and development
files using `find_pacakge(Python...)` for ceph-mgr.

* rename genl to nl:
"genl" is not very specific without more context. and libnl is actually
a library suite. so it would be better if we can rename the library to
be found to "libnl", and by following the naming convention of CMake,
in this change, Findgenl.cmake is renamed to Findnl.cmake
* Findnl.cmake: support the component argument, in our specific case,
what we want is "libnl-genl" library, which is one of the libraries
offered by libnl. so let's just make it a component.
* Findnl.cmake: should pass the names of the required variables instead of
their values to `find_package_handle_standard_args()`. before this
change, we pass `GENL_LIBRARIES` to this function. it was correct at the
first glance. but it is not able to handle the case where case where
libnl-genl is not installed. so the fix is to pass all the names of
required library paths to this function. in this change, their name
are concatenated to a single variable -- `nl_LIBRARIES`, and the
value of this variable is passed to
`find_package_handle_standard_args()`. and the error message would
be more specific this way if libnl-genl is not found:
Could NOT find nl (missing: nl_genl_LIBRARY)
* Findnl.cmake: add nl::<component> as imported library, it helps the
consumer of these libraries to import them -- no need to
specify the `target_include_directories()` separately anymore.
* move the find_package() code to where it is used. it helps to improve
the readability.
* remove `HAVE_GENL` variable: it's not used anywhere.
* drop the messages of "Not using foobar", they do not help.

DPDK only support "make". if user wants to use other generator than
"make", we will fail to build DPDK support. so we should always use
"make" here. and before using "make", we need to detect it.
* cmake/modules/BuildRocksDB.cmake: use cmake for build

just use whatever generator use specifies, and use ${CMAKE_COMMAND}

There is a lot of good stuff going on here, but nobody is investing in xio

Commit 3bde34af8a removed cython 0.29's subinterpreter check when
building the various python modules during `make`, but unforunately
they're *rebuilt* during `make install`, with the rebuild overwriting
the original build. The original fix was of course missing from the
install stage...

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.

cython 0.29 introduced a check which prevents multiple python
subinterpreters from loading the same module:
https://github.com/cython/cython/commit/7e27c7c
Unfortunately, this completely breaks ceph-mgr. Until we can
figure out a better long term solution, this commit removes
cython's subinterpreter check, via some careful abuse of the
C preprocessor.
This works because when cython is invoked, it first generates
some C code, then compiles it. We know it's going to generate
C code including:
int __Pyx_check_single_interpreter(void) { ... }
and:
if (__Pyx_check_single_interpreter())
return NULL;
So, we can do the following:
#define void0 dead_function(void)
#define __Pyx_check_single_interpreter(ARG)=ARG ## 0
This replaces the call to __Pyx_check_single_interpreter()
with a literal 0, removing the subinterpreter check.
The void0 dead_function(void) thing is necessary because
the __Pyx_check_single_interpreter() macro also clobbers
that function definition, so we need to make sure it's
replaced with something that works as a function definition.

--single-version-externally-managed is used for packaging python eggs
to deb. so the metadata can be stored in the egg, and can be accessed
by user if necessary, see [1]. but this does not apply to users who
just want to "make install" without packaging Ceph.
the problem is, if we pass --single-version-externally-managed to
setup.py, we need to pass --record or --root also. otherwise setuptools
complains:
error: You must specify --record or --root when building system packages
so in this change, we choose not to pass
"--single-version-externally-managed", unless $DESTDIR is set.
both "ceph.spec.in" and "debian/rules" set $DESTDIR when running "make
install". so we can always check $DESTDIR to tell if current "make
install" is launched by the packaging script or not. this might not be
accurate, but good enough. assuming enduser does not use DESTDIR when
running plain "make install".
