EMU_RSH handling was dropped in commit
0d62c4cfe21752df4c1d6e2c2398f15d5eaa794a.
The assignment, and subsequent free() of ex_ptr->ex_exec to so->extra
looks unsafe (double free is likely to occur).

An overdue cleanup. Remaining declarations could probably be moved in
other headers, such as slirp.h.

From: Marc-André Lureau <marcandre.lureau@redhat.com>
Originally, the patch was fixing a bunch of issues, but Peter beat me
to it with earlier commit "slirp: fork_exec(): create and connect
child socket before fork()".
Factor out socket pair creation, to simplify the fork_exec() code.
Use the name socketpair_with_oob() since the code is actually similar
to what socketpair() would do, except that it uses TCP sockets, for
SLIRP to be able to call send with MSG_OOB (since SO_OOBINLINE is set,
this could probably be faked instead on regular unix sockets though).

Nobody cares for over 14y. Somebody can revert or rewrite if
interested by that.

Looking at git history, this looks like something from the past, when
there was a tty layer. Let's remove it.

The soread() function may be used on datagram sockets, and would
provide different behaviour if HAVE_READV was set, on empty datagrams.
This looks like a minor optimization, that never has been a strong
goal for slirp.

Use g_spawn_async_with_fds() to setup the child.
GSpawn handles reaping the child, and closing parent file descriptors.

g_spawn_async_with_fds is portable on Windows, so we can now enable
fork_exec support there.

Since commit 12f8def0e02232d7c6416ad9b66640f973c531d1 (v2.9), qemu
requires Vista. Let's remove some conditional code.
Note that this introduces a missing declaration warning with mingw.
warning: implicit declaration of function 'inet_ntop'
See also: https://sourceforge.net/p/mingw-w64/mailman/message/36473782/
We could workaround it by declaring it ourself depending on __MINGW64_VERSION_*:
WINSOCK_API_LINKAGE INT WSAAPI inet_pton(int Family, PCTSTR pszAddrString, PVOID pAddrBuf);

This list is not only used to handle command to execute on guest
connection, it can also redirect to an arbitrary object, such as a

icmp_send_error() doesnt actually log messages when DEBUG is enabled.
Let's use a different define that describes better the tweaked
behaviour of the function, and avoid uncompiled code.

Make debug statements condiitonal only on slirp_debug flags, instead
of the pre-processor DEBUG blocks, as it may introduce breakage
easily, since the debug code isn't always compiled.

This will allow to have cflags for the whole slirp.mo -objs.
It makes it possible to build tests that links only with
slirp-obj-y (and not the whole common-obj).
It is also a step towards building slirp as a shared library, although
this requires a bit more thoughts to build with
net/slirp.o (CONFIG_SLIRP would need to be 'm') and other build issues.

We are moving to g_log() facilities to log errors and probably debug
messages too. Let's have the "Slirp" prefix on messages slirp produces.

Make slirp use GLib logging, instead of fprintf(), so that
applications can filter log, process it etc.
With recent versions of glib, G_MESSAGES_DEBUG must be set to "all" or
"Slirp" to see slirp debug messages.
Reformat DEBUG_MISC & DEBUG_ERROR calls to not need \n ending.

This fails to compile (all platforms):
For the windows builds, a compile failure in slirp.c:

This one is easy, it needs "build-sys: require Vista API by default
globally" series that Paolo has been sending in his last pullreqs.

make vm-build-openbsd fails here however with the:
"Cannot include hw/hw.h from user emulation" (interesting, no? ;)
Eh, git blame:
062e552 Anthony Liguori 2009-01-08 19:27 +0000 31│ #include "hw/hw.h"
-#include "hw/hw.h"
+#include "migration/vmstate.h"
+#include "migration/qemu-file-types.h"
Seems to solve it. I will send a seperate patch.

I don't have a mac, but all those linker errors look related.
I don't get why it sometime succeeds to link, but there is an obvious
mistake in "build-sys: use a seperate slirp-obj-y && slirp.mo" (Sam,
you should squash that fix)

Ok I figure that the error only happen when build for -user, however
with the build fix below, it only builds for -softmmu. So that fix is
not required.
All in all, I think we should give it another try once the "build-sys:
require Vista API" series is merged, and with the build-sys fix below
squahed in "build-sys: use a seperate slirp-obj-y && slirp.mo".

Ok, let's wait for it for that part then.
