This is the start of the Experimental USB Debugger (currently for the
Windows platform only).
Currently only supports the UHCI and xHCI controllers. The remaining
function of these two controllers and the two remaining controllers are
in the works and will be added to when time allows.
The User.dbk has been updated with (temporary) html files at
https://www.fysnet.net/bochs/user/index.html showing the process to
invoke and use the USB debugger (Section 5.8).
In its completion, this debugger will allow you to view and modify most
aspects of the specified USB controller. For example, currently you can
view and modify a TRB listed in the xHCI's Command or Event Ring. Other
aspects will be added.
I do not use and am not fluent in the use of `configure`,
`configure.ac`, and associated configuration files. I also don't use the
`gui/Makefile.in` file.
Someone that is more fluent in the way these files work, please add the
necessary items to successfully compile this PR.

- Show message box while restoring hardware state.
- Set modeless message box handle to NULL after destroying it.
- Reset all config options to default before restoring config.
- Fixed CMOS RTC value after restore if in 12-hour-mode.
- Fixed possible segfault in the plugins code caused by Voodoo plugin in VGA mode
(found at restore code testing).
As an example, when saving the state of an emulation, especially one
that has large image files and a large memory setting, there is a pause
between the time you choose a directory to save to, and the MessageBox
that states that the state was saved. During this time, there is no
indication that Bochs is doing anything. As far as the user is
concerned, Bochs froze.
So, this PR adds the capability to display a _Modeless_ message box. To
do so, at any point you need a message box shown, allowing other things
to continue to happen (SYNCHRONOUS), simply call the following line:
`void *hwnd = SIM->ml_message_box("Message Box Title", "Message Box
Text");`
Then after the task has been performed, remove the message box:
`SIM->ml_message_box_kill(hwnd);`
The function is implemented in all configurations via virtual calls,
however, the creation of the message box is currently only implemented
in the Win32 configuration. Other configurations will need this
implemented, though I do not have those configurations to test with,
except the text only config. I may get around to it :-).
This also currently only displays as the state is being saved. To
display when the state is being restored should now be a simple task by
adding the two lines shown above to the associated function.
The only drawback with this is that if the state is considerably small,
the save will take just a second or less. If so, this window will show
and then instantly be removed, possibly confusing the user. _What was
that!!_
