qdev: add return value to init() callbacks.
Sorry folks, but it has to be. One more of these invasive qdev patches.

Floppy: Properly handle Sense Interrupt Status after FDC Reset
Original text below.
Attached is a patch that changes how the emulated floppy controller replies to Sense Interrupt Status commands immediately after a controller reset. The specs state that after a Reset the 82078 goes into polling mode which needs four Sense Interrupt Status commands to be issued afterwards to clear the status of each drive. Currently we always respond to Sense Interrupt Status with a SEEK END instead of POLLING. This causes a problem with the SCO Openserver installer which is expects a POLLING state after reset. This patch returns a POLLING status for four Sense Interrupt Status requests immediately after a controller reset. This approach mirrors the way Bochs handles this situation. With the attached patch applied Openserver gets further when trying to load storage drivers from the floppy disk (blocked by another issue, patch on its way). I have successfully tested the floppy drive on the following OSs after applying this patch: Windows 98, Windows XP SP2, Linux x86 (SysRescCD 1.1.3 and Ubuntu 8.10)....
Use the ARRAY_SIZE() macro where appropriate.
Change from v1: Avoid changing the existing coding style in certain files.
