As RFC 2292 points out, some platforms (e.g. Darwin 9.8.0) provide
CMSG_FIRSTHDR(msg) which just returns msg.msg_control without first
checking if msg.msg_controllen is non-zero. We need a workaround for
such platforms not to let g_socket_receive_message() segfault.

On IPv6 sockets, set both the IPv4 and IPv6 versions of IP socket
options, in case the socket is (or might become) IPv4-wrapped. (But
ignore errors when setting the IPv4 version.)
Similarly, when joining or leaving a multicast group, pick the sockopt
to use based on the address family of the multicast address rather
than the address family of the socket.

Add g_socket_get_option() and g_socket_set_option(), wrapping
getsockopt/setsockopt for the case of integer-valued options. Update
code to use these instead of the underlying calls.

Install a public "gnetworking.h" header that can be used to include
the relevant OS-dependent networking headers. This does not really
abstract away unix-vs-windows however; error codes, in particular,
are incompatible.
gnetworkingprivate.h now contains just a few internal URI-related
functions
Also add a g_networking_init() function to gnetworking.h, which can be
used to explicitly initialize OS-level networking, rather than having
that happen as a side-effect of registering GInetAddress.

Re-#define a few socket functions to work around winsock's prototypes
having, eg, "int *" rather than "unsigned int *", or "char *" rather
than "void *".
(Also fix two places that mistakenly assumed guint==guint32.)

Darwin's poll doesn't change revents if there are no available events, though it returns 0. Initialize the fd.revents to 0 so that the test passes.
That reveals a test failure, though, because with socket streams it takes time for an event to pass through the socket. Provide an 80-usec delay to allow time for the propagation.
Solaris/OpenSolaris/OpenIndiana define FIONREAD in sys/filio.h.
This commit adds a configure check for this header, and includes
it conditionally in gio/gsocket.c.
Patch by Fabian Groffen, bug 675524.
If all members of GSocketFamily are supported on the platform, then
all of its values will be positive, and so the enum might become
unsigned, in which case testing for "family < 0" might cause warnings.
But we want to return an error if family == 0 (aka
G_SOCKET_FAMILY_INVALID) anyway, so just tweak the test accordingly.

This is needed because glib-mkenums doesn't handle #ifdef values in
enums, and so it needs to have all values always defined in the enum.
When not available, define the missing values to a negative value.
Unix and Windows gio GSocket behaves differently when the socket is
closed by the peer. On Unix, the client receives pending data before
receiving HUP. But on Windows, the HUP may come before, resulting in
unreliable and racy code. We should have same behaviour on all
platforms.
According to MSDN documentation: "an application should check for
remaining data upon receipt of FD_CLOSE to avoid any possibility of
losing data."

Some platforms don't have the source-specific multicast sockopts, and
so would fail to compile. Fix that (and return an error if the caller
tries to use source-specific). Also clarify the docs a bit.

Apparently IPV6_JOIN_GROUP and IPV6_LEAVE_GROUP are more portable than
IPV6_ADD_MEMBERSHIP and IPV6_DROP_MEMBERSHIP. (Windows and Linux have
both, but OS X only has the latter.)
g_socket_receive_with_blocking() and g_socket_send_with_blocking claim
to return -1 in error, their return type is gssize, and yet they
return FALSE if the initial g_return_val_if_fail() call fails.
https://bugzilla.gnome.org/show_bug.cgi?id=667226
Include the hostname (or proxy hostname if it was the connection to
the proxy server that failed) in the GError message when
g_socket_client_connect* fail.

On Solaris, getsockname() on an unconnected socket gives an addrlen of
0 and doesn't set the sockaddr. So use the SO_DOMAIN sockopt to find
the socket family in that case. (SO_DOMAIN doesn't exist everywhere,
so we can't use it unconditionally. Also, we have to only use it if
getsockname() fails, since SO_DOMAIN returns a bogus value for
accept()ed sockets on both Linux and Solaris...)
The docs for g_socket_set_timeout() claimed that if an async operation
timed out, the GIOCondition passed to the source callback would be
G_IO_IN or G_IO_OUT (thus prompting the caller to call
g_socket_receive/send and get a G_IO_ERROR_TIMED_OUT), but in fact it
ended up being 0, and gio/tests/socket.c was erroneously testing for
that instead of the correct value. Fix this.
socket->priv->connected was only being set if g_socket_connect()
succeeded right away; in the case where it returns G_IO_ERROR_PENDING,
it never got set. Fix that by having g_socket_check_connect_result()
set it on success.
To help cross compilation, don't use glib-genmarshal in our
build. This is easy now that we have g_cclosure_marshal_generic().
In gobject/, add gmarshal.[ch] to git (making the existing entry
points stubs).
In gio/, simply switch to using g_cclosure_marshal_generic().
