Update usb_ehci.cc (#271) 
No reason to stop executing the Async list simply because the driver
didn't clear the IAA bit in the Status register.

Normally, a driver should clear it, but there is no instruction in the
specification to stop the Async list simply because this bit isn't
cleared.

Debug log is still present to inform the user.

1ff88fdd05 VGA_MEM_FIX: Added text buffer in legacy format to simplify text update. 
Using character / attribute pairs expected by the gui text update makes the
update code simpler and faster.

117f71a185 VGA_MEM_FIX: Some odd/even mode changes for correctness.

945ee597f0 Added currently disabled set of fixes for the VGA memory management. 
- Added disabled definition VGA_MEM_FIX in vgacore.h. The VGA core code works as
  usual unless you uncomment the define.
- 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.

1ebe15e3fc Rewrite of the VGA timing code. 
- Added VSYNC timer handler using vertical total usec. The calling time is defined
  as vertical retrace end and it updates the CRTC start address like real VGA does.
  It also calculates the display start time used when reading the input status register.
  The VSYNC timer is disabled in Voodoo / Banshee modes.
- Improved VGA timing calculation (e.g. vertical blanking and retrace start).

For APIC-access VM exits and for VM exits caused by:

- EPT misconfigurations
- page-modification log-full events or
- SPP-related events
the value saved depends on whether the VM exit occurred during delivery of an event through the IDT ...

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.

Fix niclist.exe crash when writing to string returned by PACKET.DLL (#179) 
Seemingly Npcap returns a read-only string and `niclist.exe` tries to
modify (tokenize) it using `strtrok()`.
That results in the crash: #161

Probably related to
https://github.com/the-tcpdump-group/libpcap/pull/949.

Here is my try at fixing this.
For successful modification I propose to use a stack-allocated copy
instead of the original (const) version string.

Now
[packetWin7/Dll/Packet32.cpp#L159](https://github.com/nmap/npcap/blob/a41bc6a/packetWin7/Dll/Packet32.cpp#L159)
seems to initialize `const char PacketLibraryVersion[]` from the define
`WINPCAP_VER_STRING`, which seems to be of arbitrary length:
```
__declspec(dllexport) const char PacketLibraryVersion[] = WINPCAP_VER_STRING; 
```

Let's search for the longest string present in their repo:
```
$ git log -u version.h | awk 'BEGIN { FPAT="(([^ \t]+)?(\"[^\"]+\")?)+" } /^.*define.+WINPCAP_VER_STRING.+[0-9]/ { gsub(/"/, "", $NF); print $NF }' | sort -Vu | while read; do printf "%4s    %s\n" ${#REPLY} "${REPLY}"; done | sort -n

```

So it's 10 characters. (Sorry for the long Bash one-liner)

Also I visited the older code from WinPcap, and it seems it used a
64-byte long string:
[packetNtx/Dll/Packet32.c#L105](https://github.com/wireshark/winpcap/blob/267327e/packetNtx/Dll/Packet32.c#L105)
```
char PacketLibraryVersion[64]; 
```

So I assumed it's safe to allocate the same on stack.

Added save/restore support for the ESCD space in the flash BIOS ROM. (#162) 
These changes only have an effect when using a BIOS image designed for
real hardware (tested with asus_p6np5.bin). When using Bochs BIOS no
data will be saved / restored, since the 'flash_modified' value is
always set to 'false'. Saving ESCD data on exit is not implemented yet,
but it shouldn't be hard to do.
