connected device. For now this feature is only used by the 'disk' device to
specify an alternative redolog filename of some image modes.
- added new methods set_option() and timer() to the base class usb_device_c.
The timer() method is periodicly called from the HC's frame timer code.
- moved runtime device change stuff from the parameter handler to the end of
timer() methods of all hubs. This makes sure that all parameters for the
device have been set at connect time. TODO: this technique could also be used
for the floppy and cdrom media change.
- create config parameters for USB depending of the defined number of ports
- removed obsolete comment
- bx_param_num_c flag USE_SPIN_CONTROL now available for all config interfaces
* USB runtime options moved to a new dynamic menu
* USB host controllers create own submenus in init()
* USB runtime parameter handlers simplified
* TODO: related changes in the wx and win32dialog code
keyboard and usb_hid code to use them
- removed keyboard handling from the USB host controller code
- removed no longer needed USB stubs from the devices code
- converted removable mouse variables to a structure
- some more registers converted from struct to Bit16u / Bit32u
- some progress with save/restore support
- small interrupt handling rewrite
- report misaligned read/write access
