Recent work on the netxml-ups driver made me realize that it would be very useful to be able to dynamically add/remove file descriptors we want to monitor for activity (instead of just a single extrafd). We'll probably also need this, in order to support asynchronous I/O in libusb-1.0. The latter would be a huge improvement over the existing libusb-0.1 (compatibility) interface we're using right now.

No objections here.

Since the libusb-1.0 implementation was fairly Linux-centric to start with, I presume we will have a long time before all platforms support it as well as libusb-0.1 -- but if you need the extra file descriptors for other drivers, I don't see a reason not to add that support.
