[tarantool-patches] [PATCH 0/2] box: implement on_shutdown triggers

[Serge Petrenko <sergepetrenko@tarantool.org>]

This patchset adds on_shutdown triggers which can be registered from lua
via box.ctl.on_shutdown() and are run on tarantool shutdown.

Issue: https://github.com/tarantool/tarantool/issues/1607
Branch: https://github.com/tarantool/tarantool/tree/sp/gh-1607-on-exit-triggers

First patch was originally made by Kostja and implemented on_shutdown
triggers. I had to alter it a bit so that on shutdown box_free() is
called after coio_shutdown(). Otherwise tarantool hung on shutdown
occasionally. I also factored out trigger_run() into a separate function 
box_run_on_shutdown_triggers(), so that on_shutdown triggers are still
run before anything else is freed or shut down.

Second patch expands box.ctl interface by introducing box.ctl.on_shutdown()
function to register on_shutdown triggers from lua.
