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.
