slirp: Fix unusual "comments" in unused code
cppcheck detected two rather strange comments which were notcorrectly written as C comments.
They did not cause any harm because they were framed by#ifdef notdef ... #endif, so they were never compiled.
Fix them nevertheless (we could also remove the unused code)....
slirp: Forward ICMP echo requests via unprivileged sockets
Linux 3.0 gained support for unprivileged ICMP ping sockets. Use thisfeature to forward guest pings to the outer world. The host admin has toset the ping_group_range in order to grant access to those sockets. To...
slirp: Fix restricted mode
This aligns the code to what the documentation claims: Allow everythingbut requests that would have to be routed outside of the virtual LAN.
So we need to drop the unneeded IP-level filter, allow TFTP requests,and add the missing protocol-level filter to ICMP....

slirp: Factor out internal state structure
The essence of this patch is to stuff (almost) all global variables ofthe slirp stack into the structure Slirp. In this step, we still keepthe structure as global variable, directly accessible by the wholestack. Changes to the external interface of slirp will be applied in...
slirp: Make IP packet ID consistent
Currently, ip_id is always initialized to 0 on slirp startup (despitethe broken attempt to derive it from the clock). This is good forreproducibility. But it is not preserved across save/restore. This patchtherefore drops the dead initialization code from ip_init and introduces...
slirp: Drop dead code
After all its years inside the qemu tree, there is no point in keepingthe dead code paths of slirp. This patch is a first round of removingusually commented out code parts. More cleanups need to follow (andmaybe finally a proper reindention)....
slirp: Drop statistic code
As agreed on the mailing list, there is no interest in keeping theusually disabled slirp statistics in the tree. So this patch removesthem.
slirp: Rework internal configuration
The user mode IP stack is currently only minimally configurable /wrt toits virtual IP addresses. This is unfortunate if some guest has a fixedidea of which IP addresses to use.
Therefore this patch prepares the stack for fully configurable IP...
Sparse fixes: NULL use, header order, ANSI prototypes, static
Fix Sparse warnings: * use NULL instead of plain 0 * rearrange header include order to avoid redefining types accidentally * ANSIfy SLIRP * avoid "restrict" keyword * add static
