slirp: Fix requeuing of batchq packets in if_start

In case we requeued a packet that was the head of a longer session
queue, we failed to restore this ordering. Also, we did not properly
deal with changes to Slirp::next_m.

Instead of a cumbersome roll back, this fix simply avoids any changes...

slirp: Only start packet expiration for delayed ones

The expiration timeout must only affect packets that are queued due to
pending ARP resolutions. The old version broke ping e.g.

slirp: Read current time only once per if_start call

No need to update the current time for each packet we send from the
queue. Processing time is comparably short.

Delayed IP packets

In the current implementation, if Slirp tries to send an IP packet to a client
with an unknown hardware address, the packet is simply dropped and an ARP
request is sent (if_encap in slirp/slirp.c).

With this patch, Slirp will send the ARP request, re-queue the packet and try...

slirp: Drop link_up checks from if_output and slirp_socket_can_recv

link_up is true once slirp is initialized, so these check are really not
required.

slirp: Factor out internal state structure

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...

slirp: Use internal state in interface

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....

slirp: Drop dead code

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. More cleanups need to follow (and
maybe finally a proper reindention)....

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

Special-case CTL_ALIAS instead of CTL_DNS in udp loopback test.

At the same time remove a bogus test (tested by Jason Wessel).
Quiet some gcc4 warnings from slirp compilation.
