Allocate the internal slirp state dynamically and provide and call slirp_cleanup to properly release it after use. This patch finally unbreaks slirp release and re-instantiation via host_net_* monitor commands.

This now also exports the internal state to the slirp users in qemu, returning it from slirp_init and expecting it along with service invocations. Additionally provide an opaque value interface for the callbacks from slirp into the qemu core.

The essence of this patch is to stuff (almost) all global variables of the slirp stack into the structure Slirp. In this step, we still keep the structure as global variable, directly accessible by the whole stack. Changes to the external interface of slirp will be applied in the following patches.

Slirp doesn't invoke slirp[_can]_output before it is initialized. The motivation for these checks (3b7f5d47) no longer applies. So drop them. Note: slirp_vc will become invalid if the slirp stack is removed during runtime. But this is no new bug and will be fixed later.

Currently, ip_id is always initialized to 0 on slirp startup (despite the broken attempt to derive it from the clock). This is good for reproducibility. But it is not preserved across save/restore. This patch therefore drops the dead initialization code from ip_init and introduces ip_id to the persistent slirp state.

In order to prepare re-initialization and multi-instance slirp, factor out init code that is of global scope and (at least for now) only need to be run once.

After all its years inside the qemu tree, there is no point in keeping the dead code paths of slirp. This patch is a first round of removing usually commented out code parts.

With the internal IP configuration made more flexible, we can now enhance the user interface. This patch adds a number of new options to "-net user": net (address and mask), host, dhcpstart, dns and smbserver. It also renames "redir" to "hostfwd" and "channel" to "guestfwd" in order to (hopefully) clarify their meanings. The format of guestfwd is extended so that the user can define not only the port but also the virtual server's IP address the forwarding starts from.

The user mode IP stack is currently only minimally configurable /wrt to its virtual IP addresses. This is unfortunate if some guest has a fixed idea of which IP addresses to use. Therefore this patch prepares the stack for fully configurable IP addresses and masks. The user interface and default addresses remain untouched in this step, they will be enhanced in the following patch.

So far a couple of slirp-related parameters were expressed via stand-alone command line options. This it inconsistent and unintuitive. Moreover, it prevents both dynamically reconfigured (host_net_add/ delete) and multi-instance slirp. This patch refactors the configuration by turning -smb, -redir, -tftp and -bootp as well as -net channel into options of "-net user". The old stand-alone command line options are still processed, but no longer advertised. This allows smooth migration of management applications to to the new syntax and also the extension of that syntax later in this series.

Hi all, this patch implements zooming capabilities for the sdl interface. A new sdl_zoom_blit function is added that is able to scale and blit a portion of a surface into another. This way we can enable SDL_RESIZABLE and have a real_screen surface with a different size than the guest surface and let sdl_zoom_blit take care of the problem.

[brought forward to current qemu-kvm.git] This patch implements the missing qemu logic to interpret a '-drive .. serial=XYZ ..' flag for a virtio_blk device. The serial number string is contained in a skeletal IDENTIFY DEVICE data structure and this structure is made available to the guest virtio_blk driver via pci i/o region 0.
