cephfs-shell: move source to separate subdirectory
This ensures the package discovery done by python setuptools >= 61
doesn't get confused when building cephfs-shell and cephfs-top.
This commit moves cephfs-shell to a separate "shell" subdirectory,
which is the same approach we've already got with the cephfs-top
tool being in a separate "top" subdirectory.

cmake: link denc-mod-rgw against Boost::filesystem
to address the runtime link failure.
this change is not cherry-picked from main branch. as, in main branch,
the Boost::filesystem linkage is pulled in by rgw_common, which was
changed to a static library in 43d10b9e44ca50700e9076a47f2c38b360d1d632.
but this change is not included in pacific. so rgw added the linkage
via rgw_libs CMake variable. unfortunately, the lexical scope of this
variable does not not include tools/ceph-dencoder/CMakeLists.txt, so
we have to add this linkage manually here.

rbd-mirror: resume pending shutdown on error in snapshot replayer
If a shutdown is requested, e.g. by update_pool_replayers() because
remote RADOS instance got blocklisted, and Replayer::shut_down() pends
it on completion of current snapshot sync, it gets stuck if replayer
encounters an error in the interim. This is particularly likely in the
blocklist case: a higher layer may detect that client got blocklisted
and request a shutdown first, and then when replayer sees EBLOCKLISTED
in turn, it calls handle_replay_complete() -- which does not resume
a pending shutdown. Because update_pool_replayers() blocks on shutdown
with Mirror::m_lock held, eventually the entire daemon hangs in
perpetuity.

tools/ceph-dencoder: register dencoders in plugin
so we can allocate and deallocate dencoders in the shared library,
instead of allocating them in the shared library, while deallocating
them in the executable.
after this change
- the plugin holds the strong references of the dencoders
- the registry holds the plugins and weak references of dencoders
- the dencoder shared libraries calls the method exposed by plugin
to alloc/dealloc the dencoders
this change should address the segfault when compiling with Clang.
FreeBSD ceph-dencoder crashes in the exit() calls, due to
invalid pointer references during the release process of
the loaded libraries.
Often this is signaled by libc reporting:
__cxa_thread_call_dtors: dtr 0x47efc0 from unloaded dso, skipping
The cause for this is different behaviour between FreeBSD and Linux:
https://groups.google.com/g/bsdmailinglist/c/22ncTZAbDp4/m/Dii_pII5AwAJ
_The FreeBSD implementation here looks racy. If one thread dlcloses an
object while another thread is exiting, we can end up calling a
function at an invalid memory address. It also looks as if it may
be possible to unload one library, load another at the same address,
and end up executing entirely the wrong code, which would have some
serious security implications.
The GNU/Linux equivalent of this function locks the DSO in memory
until all references to it have gone away. A call to dlclose() on
GNU/Linux will not actually unload the library until all threads
with destructors in that library have been unloaded. I believe
that this reuses the same reference counting mechanism that
allows the same library to be dlopened and dlclosed multiple times.
