ev: add signal() to catch signals safely too Uses the 'self-pipe trick' to catch and process signals outside of the signal environment. A few XXX remains, but this is good enough to hit the tree.

ev: move some functions to ev/global.ha Move there functions that relies on the global event loop.

adapt to new ev API

ev: fmt

ev: add loopbreak to the API

ev: rework the API Allow to create custom event loops, but still retain the possibility to just use a global one.

ev: remove unnecessary check

shinsha: adapt from ev::any change

ev: inline use nullable *opaque instead of ev::any ev::any was just to save some typing; not sure it's worth it. Can be easily confused with ev::READ and ev::WRITE.

ev: use def instead of const for globals I actually don't get the difference between def and const. maybe def is guaranteed to be a compile-time constant (just guessing). Other "#defines" in the hare stdlib seem to use def tho, so follow here too.

ev: use two queues avoids issues with adding/removing elements from the 'working' queue. ev::add and ev::del only touch the "wip" queue, while poll only touches the "working" queue. This technically has the consequences that if from event A we remove event B which is pending and not yet processed, we may still fire B once.

ev: process all the events This was intended as an optimization: poll returns the number of elements in the pollfd set which had events. Can be revised in the future.

typo right before the import...
