12cace4c5a Some work on async packet and seek emulation support.
- deactivate seek timer when operation is cancelled.
- set async packet mode with a separate method at connection time.
- renamed some variables and prepared seek emulation for USB disk writes.

0b432b313f Added seek emulation support for USB harddisk reads and cleaned up the
MSD / SCSI code.
TODO list (async packet and seek support):
- seek emulation for USB harddisk write commands
- seek emulation for floppy
- async packet support for UHCI and xHCI
- improve and clean up OHCI async packet code

491dc311ca Some work for asynchronus USB packet handling (needed by disk/cdrom seek emulation).
- Common USB code prepared for async USB packet handling (ported from an earlier
  Qemu version).
- Added simple async packet handling to OHCI (partly ported from earlier Qemu).
- Implemented USB cdrom seek emulation for hubs with async packet support. The
  legacy code is still present for hubs without this feature.
- For UHCI and xHCI the callback is set to NULL to force the usage of the
  legacy cdrom read code.
TODO: clean up OHCI code, async support for UHCI and xHCI, seek emulation for
USB harddisk and floppy.

4b83f9e899 If the debug mode is enabled for usb_msd, turn it on for the SCSI device, too,
Don't try to insert cdrom media if device/image path is empty.

38fbdaa7e8 Added runtime config handler for the USB cdrom and modified parameter handling
similar to the ATAPI implementation (including locked tray case).
Fixed status indicator activity and minor other changes.

c217470150 Started implementing save/restore support for SCSI requests
- save function implemented using a dummy parameter that only receives the
  result of the save operation. The parameter's save/restore handlers doing
  the main job. The numerical values of the requests are saved in a separate
  text file. The data transfer buffers are saved as binary files.
- the request data buffers are now created dynamicly
- TODO: restore SCSI requests

a5984f7cd0 Some work on the USB MSD emulation
- prepared seek timer feature
- removed error handling that would cause a segfault
- better error handling for CD-ROM read errors

39890d308d Connecting USB CD-ROM without media present now supported

9554a2133e Always enable the portable ISO image file support. The option --enable-cdrom now
only controls the presence of platform-specific code to access CDROM/DVD devices

b452803be5 Preparing lowlevel cdrom rewrite
- use #if BX_SUPPORT_CDROM instead of #ifdef LOWLEVEL_CDROM
- devices with cdrom support now use the base class cdrom_base_c
- cdrom count variable moved to cdrom.cc
- cdrom_misc.cc: don't use ioctl's for ISO files
