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
Changes in v2:
- added 3rd patch which passes signals to triggers.
- run on_shutdown triggers even if box is not configured.
- add a documentation request to the 3rd patch.
First patch was originally made by Kostja and implemented on_shutdown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.
Third patch adds the ability to pass signal which caused termination to
the on_shutdown trigger.
