Assume unix platforms support the original POSIX.1 standard.
Specifically, assume that if G_OS_UNIX, then we have chown(),
getcwd(), getgrgid(), getpwuid(), link(), <grp.h>, <pwd.h>,
<sys/types.h>, <sys/uio.h>, <sys/wait.h>, and <unistd.h>.
Additionally, since all versions of Windows that we care about also
have <sys/types.h>, we can remove HAVE_SYS_TYPES_H checks everywhere.
Also remove one include of <sys/times.h>, and the corresponding
configure check, since the include is not currently needed (and may
always have just been a typo for <sys/time.h>).

Rather than having lots of obscure platform-based #ifdefs all over
gio, define some macros in gcredentialsprivate.h, and use those to
simplify the rest of the code.

On Windows and OS X, FIONREAD on a UDP socket gets the total number of
bytes available, not the number of bytes available in the next packet,
which is the more useful number (and how the function always behaved
on Linux).
On OS X, fix this by using SO_NREAD. On Windows, fix this by doing a
MSG_PEEK recv() into a giant buffer, since there is apparently no
other way to get the information.

The requested_conditions list access is not threadsafe. When passing
the socket ownership from a GSource callback to another thread, which
also creates a GSocketSource for the socket, it can happen that the
original GSocketSource is finalized at the same time as the new one
is created. This would cause inconsistencies in the requested_conditions
list and can cause assertions or completely undefined behaviour.

With UDP sockets, g_socket_bind() with allow_reuse=TRUE on Linux
behaved in a way that the documentation didn't suggest, and that
didn't match other OSes. (Specifically, it allowed binding multiple
multicast sockets to the same address.)
Since this behavior is useful, and since allow_reuse didn't have any
other meaning with UDP sockets, update the docs to reflect the Linux
behavior, and make it do the same thing on non-Linux.

GPollableSource and GSocket's "broken" source never trigger on their
own, so with the changes to GSources in the last cycle, their check
and prepare functions are unnecessary (and undesired).

For the glib-defined source types, and any source type that defines a
closure callback but not a closure marshal, use
g_cclosure_marshal_generic. And then remove all the other remaining
source closure marshals.

As it turns out, we have examples of internal functions called
type_name_get_private() in the wild (especially among older libraries),
so we need to use a name for the per-instance private data getter
function that hopefully won't conflict with anything.
Use the same code GSocket does, to try SOCK_CLOEXEC first, and then
fall back to FD_CLOEXEC if it fails. (And fix that code to not call
fcntl if SOCK_CLOEXEC worked.)

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.)
