I actually planned to use interface initially but there are few issue with
it.

- as I mentioned above, not all handles will always allow using file
descriptors (e.g. timer for kqueue)
- abstract class allow internal api defintion and not calling the PHP
functions internally (that's how the above can be handled as well)
- it would require exposing the actual fd numbers for streams which after
some thinking might not be best idea because it would make easier for
people to have two streams for a single fd which might cause issues with
filtering, buffering and so on.

I put there just those that I actually plan to implement and are relatively
straight forward. For mysqli it might require some abstraction to get the
mysqlnd stream so would need to check it out first. In other words I
haven't fully investigated it yet. But it should be probably added too.

Kind regards,

Jakub
