c74398e130 Modules: make unloading module more safe 
As we know if a module exports module-side data types,
unload it is not allowed. This rule is the same with
blocked clients in module, because we use background
threads to implement module blocked clients, and it's
not safe to unload a module if there are background
threads running. So it's necessary to check if any
blocked clients running in this module when unload it.

Moreover, after that we can ensure that if no modules,
then no module blocked clients even module unloaded.
So, we can call moduleHandleBlockedClients only when
we have installed modules.

83de18805c Modules hooks: do not re-enter in hooks. 
Calling a module hook callback may result in callback operations in turn
triggering other events the module is subscribed too. We don't want to
trigger those, it's unsafe and quite confusing, and to do it correcly we
would need to maintain an event list: quite a more complex
implementation.

916c4e5d86 moduleRDBLoadError(): io->ctx may be NULL. 
The correct way to access the module about a given IO context is to
deference io->type->module, since io->ctx is only populated if the user
requests an explicit context from an IO object.

721d3c9e0c TerminateModuleForkChild(): move safety checks there. 
We don't want that the API could be used directly in an unsafe way,
without checking if there is an active child. Now the safety checks are
moved directly in the function performing the operations.

82845f8d04 TerminateModuleForkChild(): use wait4 for safety. 
In theory currently there is only one active child, but the API may
change or for bugs in the implementation we may have several (it was
like that for years because of a bug). Better to wait for a specific
pid and avoid consuing other pending children information.
