Applied patch for builtin "slirp" (user-mode networking) support. This version
is almost a port of the Qemu 1.1.2 implementation. It has been tested successfully
on Linux and Windows (MinGW/MSYS). The networking module is currently called
"slirp_new", since the "slirp" backend module still exists.

TODO list:
  - MSVC support (requires container_of() macro replacement)
  - apply fixes and improvements from recent Qemu releases
  - use our TFTP implementation to reduce code duplication
  - check if we can share ARP and DHCP support with "vnet"
  - add SMB support on Linux
  - finally remove the slirp backend module support
