GDatagramBased is an interface abstracting datagram-based communications
in the style of the Berkeley sockets API. It may be contrasted to (for
example) GIOStream, which supports only streaming I/O.
GDatagramBased allows socket-like communications to be done through any
object, not just a concrete GSocket (which wraps socket()).
This adds the GDatagramBased interface, and implements it in GSocket.

The Visual Studio projects used a default setting for link-time code
generation, which is a part of the various linker optimizations that is
available, which is set as /LTCG for Visual Studio 2013 and earlier.
This changed in Visual Studio 2015 to become /LTCG:incremental, which would
cause GResources-generated code to be optimized out during linking, unless
they were referred to directly in the main line code (such as when the
GResource is manually registered), causing programs to crash as a result as
they can't find the needed code/data at run time.
Fix this by explicitly setting /LTCG for all release builds, for Visual
Studio 2010 and later.

Use /ltcg (link time code generation) for linking as well.
In fact, whole program optimization and /ltcg are the default for Release
builds, so we don't really have to set them explicitly in the projects, so
as a result, we can clean up the projects a little bit.

It seems that VS 2015 optimizes out the constructor on windows,
so it is better to use a DllMain to initialize the library
and keep using a normal constructor on the other platforms.
This research was done by Arnav Singh.

When G_OUTPUT_STREAM_CLOSE_TARGET is set,
g_output_stream_real_splice was not returning -1 in any error
cases, since the success flag was being overwritten.

By default g_log_default_handler always assumes that stdout
and stderr are file descriptors 1 and 2. On Win32 this isn't
always the case as the win32 API functions AttachConsole and
freopen can be used to dynamically attach GUI applications to
a console and the file descriptors of stderr and stdout will
become different than 1 and 2.
Fix it by using fputs with the FILE directly instead of
using the file descriptors.

The VerifyVersionInfo() Win32 API has been deprecated in Windows 10, and
there is no direct replacement for it, except by using a lower-level
RtlGetVersion() that we aquire from the Windows DDK or from ntdll.dll.
Switch g_win32_check_windows_version() to use RtlGetVersion(), and
compare its results with the input parameters.

The environment variable DISPLAY makes sense only for X11, it should
not be set in gio.
Beside, if the backend is not X11 but Wayland, forcing the value of
DISPLAY to the Wayland display will confuse the backend selection and
possibly crash the applications.

Commit a0cefc2217 introduced an unresolved
symbol, g_socket_send_message_with_timeout(), on win32. Windows
unfortunately isn’t clever enough to fill in the gaps and magic up the
implementation of that function from nowhere, so we had better do it
ourselves.
Factor the blocking behaviour out of g_socket_send_message() into a new
internal g_socket_send_message_with_timeout().

Some testutils external symbols are marked semi-internals, other
internals. It is not obvious what guarantees these symbols provide.
However, tests are now installable, and require the ABI stability
that glib provides for the rest of the symbols.
In my case, I would like to introduce g_assert* compat code for older
glib versions, and be able to use the so-called "internal" ABI.
I propose this change to the headers comments to explain the stability
guarantees. Removing the "internal" = you must not use this, in favor
of semi-internal = this is not documented.

5d68947 factored out resuable items, but some of these are only for
*NIX builds, which will break the build on Windows. Fix this by
building these portions only when !G_OS_WIN32.

The value of g_socket_is_connected() gets stuck high if the GSocket is
shut down in two steps:
g_socket_shutdown (socket, TRUE, FALSE, NULL);
g_socket_shutdown (socket, FALSE, TRUE, NULL);
rather than one:
g_socket_shutdown (socket, TRUE, TRUE, NULL);
Fix that by tracking the connected status for the read half and the
write half of the connection separately.

In all these functions, group_name is guaranteed to be non-NULL by the
function preconditions, so there is no need to handle it as NULL when
building error messages. Remove some unnecessary string literals as a
result.

set_auth_msg() was returning FALSE to indicate error, but all its
callers were expecting a negative return value to indicate error. This
was causing memory leaks for the GError, and errors to not be reported.
Coverity CID: 1325357
If --prefix is specified, marshaller_prefix is allocated and never
freed. It does not actually have to be allocated — just use the static
string from argv.
Coverity CID: 1325370
If the certificate constructor is called as:
g_tls_certificate_new_from_pem (data, length, NULL);
and PEM parsing fails for the private key, the function would have
continued to try and create a certificate using a NULL key_pem value,
which would have failed or crashed.
Use g_propagate_error() correctly to avoid this.

Remove some outdated references to an old example, and add a row in the

If an error in the underlying sendmmsg() syscall occurs after
successfully sending one or more messages, g_socket_send_messages()
should return the number of messages successfully sent, rather than an
error. This mirrors the documented sendmmsg() behaviour.
This is a slight behaviour change for g_socket_send_messages(), but as
it relaxes the error reporting (reporting errors in fewer situations
than before), it should not cause problems.

Add support for receiving multiple messages with a single system call,
using recvmmsg() if available. Otherwise, fall back to looping over
g_socket_receive_message().
This adds new API, g_socket_receive_messages(), and corresponding unit
tests.
https://bugzilla.gnome.org/show_bug.cgi?id=751924
In order to support per-operation timeouts on new API like
g_socket_receive_messages(), the internal GSocket API should use
timeouts rather than boolean blocking parameters.
(timeout == 0) === (blocking == FALSE)
(timeout == -1) === (blocking == TRUE)
(timeout > 0) === new behaviour
https://bugzilla.gnome.org/show_bug.cgi?id=751924
This complements the GOutputMessage struct. It will shortly be used for
adding a g_socket_receive_messages() function, but needs to be committed
first to allow some internal refactoring of GSocket.
