9d9d5b22eb Some work on the MSVC workspace files. 
Don't generate debug information for release builds.
Fixed some of the "OutDir" settings.

Allow BX_SHARE_PATH to be used in BIOS paths (#288) 
This allows the Window's Environment variable BX_SHARE_PATH to be used
in paths within your bochsrc file.

Environment variable:
`BX_SHARE_PATH`
Value:
`D:\some\path`

Before:
`romimage: file=D:/some/path/bios/BIOS-bochs-latest`
After:
`romimage: file=$BXSHARE/bios/BIOS-bochs-latest`

Please note that I don't know why the parameter was initially empty. Was
this to catch a base/default parameter?
If the `lpValueName` parameter is NULL or an empty string, Windows will
return a (possibly non-existent) default value.
With this PR, we specify the actual parameter of `BX_SHARE_PATH`.

9fbaadd894 Started updating the standard workspace for MSVC. 
Updated AVX and FPU project files to make them compile. Added new project file
for the softfloat3e module. With the current version the softfloat3e.lib is created,
but it doesn't link with bochs.exe, so the build fails with more than 100 unresolved
externals. Manually linking on the MSVC command line using the created *.lib and *.obj
files works and bochs.exe is usable. I still haven't found out why linking from
the IDE fails.
TODO: After fixing this issue, updating the plugins workspace should be no problem.

a3ff473642 Modified softfloat3e Makefile to fix compüilation with MSVC nmake. 
Since GNU make and MSVC nmake need special rules for compiling this module that
causes failure with the other 'make' variant, the configure script needs to
comment out incompatible rules. Using symbols GNU_MAKE_ONLY and NMAKE_ONLY to
enable only one of the rulesets only.
Since one of the MSVC nmake rules uses curly brackets the shortcut script
.conf.win64-vcpp needs to be modified to exclude cpu/softfloat3e/Makefile
from removal of these usually unwanted characters.

Initial start of the USB Debugger (#165) 
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.

No reason to stop executing the Async list simply because the driver

cleared.

- Added correct implementation of the "chain four" and "odd/even" addressing mode.
  This should fix the Debian / GRUB boot issue (#257) with both Bochs VBE and Cirrus.
- Added some compatibility code to make the gui text update work as usual.
- Tested all VGA modes except 256-color word mode (no test case).
- Some more testing with old DOS games may be required before I enable it by default
  and finally remove the legacy code.

cfa7276cb9 Added support for driving the VGA display update timer with VSYNC. 
- Using the special value of 0 enables this feature. In that case the vertical
  frequency is used for the display updates. The update() method is called at
  the "vertical retrace end" time and sets the time of the display start. This
  value is used to set the vertical retrace indicator in VGA register 0x03da.
- This feature is not yet enabled if Voodoo support is present. The Voodoo device
  has it's own vertical timer and needs some more testing and possibly some changes.
