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.

0d49d2a8df Added 'flash_data' parameter to the romimage option. 
This parameter defines the file name for the flash BIOS config space loaded
startup if existing and saved on exit if modified. The Bochs BIOS doesn't
use this feature yet. Updated 'romimage' option documentation.

20b61b31f2 Improved parsing bochsrc options passed on the command line (see issue #160). 
If the last char of an argument is a colon, equal sign or comma and there is
at least one more argument, then concatenate these arguments to one and pass
it to parse_line_unformatted().

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.
