  lib: Add asserts to make sure running ioloop is always current_ioloop

We could also switch current_ioloop to the running ioloop temporarily while
calling callbacks, but this behavior is probably clearer. All of the
existing code should already work this way.

Add the asserts after IO or timeout callback is called, so if the assert
triggers, we can find out which callback caused the change. The initial
assert in io_loop_handler_run() is enough to verify that the initial
ioloop is correct.
