244e35af87 Banshee: Skip address wrap during display update to avoid segfault.

426bd50b90 Cirrus VGA fixes to make original VGABIOS work correctly with XP (#319). 
- Allow BitBlt start after BitBlt reset with one register write.
- Using dstpitch = 0 is valid if bltheight = 1. Skip redraw to avoid division
  by zero error. Win2k and XP are using these settings at startup and expect a
  small piece of memory to be set to 0xff. That's why the LGPL'd VGABIOS for
  Cirrus still has the Win2k hack clearing all memory with 0xff.

7dd1a7be9e Big update of builtin slirp networking support (IPv4 only). 
Update of existing files based on libslirp 4.7.0 code. It compiles and works
on Linux (gcc 10.4) and Windows (mingw/msys with gcc 14 and VS2019).
Functionality tested on both platforms with Linux guest OS (Firefox shows website).
Next step will be the start of the IPv6 integration.

Volker Ruppert
49736ddcf0 More accurate fix for the BIOS issue #268. 
- lcmpul needs to preserve EAX and EBX, since the result is read from status flags.

  and the hiword in BX. Now doing the shift operation with the 16-bit registers
  (lsr bx / rcr ax).
- TODO: the other helper functions need to be reviewed.
