The hotplug mediabay has tendrils deep into drivers/ide code which makes a libata port reather difficult. In addition it's ugly and could be done better. This reworks the interface between the mediabay and the rest of the world so that: - Any macio_driver can now have a mediabay_event callback which will be called when that driver sits on a mediabay and it's been either plugged or unplugged. The device type is passed as an argument. We can now move all the IDE cruft into the IDE driver itself - A check_media_bay() function can be used to take a peek at the type of device currently in the bay if any, a cleaner variant of the previous function with the same name. - A pair of lock/unlock functions are exposed to allow the IDE driver to block the hotplug callbacks during the initial setup and probing of the bay in order to avoid nasty race conditions. - The mediabay code no longer needs to spin on the status register of the IDE interface when it detects an IDE device, this is done just fine by the IDE code itself Overall, less code, simpler, and allows for another driver than our old drivers/ide based one.
