There's no need to re-build the a{sv} array, just get it right out of
the parameters. Also avoid some string copies.

This is to match g_dbus_connection_new(). This extension allows us to
extend GDBusAuthObserver to also be used in client-side authentication
in the future (right now it's only used on the server-side).
This is needed to e.g. allow encoding maybe types (once we add
G_DBUS_CAPABILITY_FLAGS_MAYBE_TYPES) if, and only if, that capability
has been negotiated with the peer (via authentication).
This uncovered a bug in name watching if the name wasn't activatable.
Also provoked the need for on_connection variants of g_bus_watch_name
(added g_bus_watch_proxy's variant as well).
Also make the gdbus-example-server include some example
annotations. The output looks like this:
$ gdbus introspect --session --dest org.gtk.GDBus.TestServer --object-path /org/gtk/GDBus/TestObject
node /org/gtk/GDBus/TestObject {
interface org.freedesktop.DBus.Properties {
methods:
Get(in s interface_name,
in s property_name,
out v value);
GetAll(in s interface_name,
out a{sv} properties);
Set(in s interface_name,
in s property_name,
in v value);

PropertiesChanged(s interface_name,
a{sv} changed_properties);
};

Introspect(out s xml_data);

This makes it possible to use the cached properties mechanism even if
constructing the proxy with the DO_NOT_LOAD_PROPERTIES flag.
This is useful for cases where you obtain the and track object
properties out-of-band. For example, in udisks, the plan is to have
something like this
Manager.GetObjects (out ao paths, out aa{sa{sv}} all_properties);
Manager.ObjectAdded (o path, a{sa{sv}} all_properties);
Manager.ObjectChanged (o path, a{sa{sv}} all_properties);
Manager.ObjectRemoved (o path, a{sa{sv}} all_properties);
E.g. the first GetObjects() call will return *all* data about *all*
exported objects. Further, this way a client will only need to listen
these three signals (three AddMatch) on the Manager object and it will
never need to do GetAll() etc (e.g. can use DO_NOT_LOAD_PROPERTIES).
(Of course this only works if the client is interested in all
objects... while this is true for udisks it is generally not true for
other D-Bus services).
Also use expected_interface to check for programming errors.
These are included wholesale in the docs, and the copyright
headers make them even more overwhelming. Plus, we don't have
copyright headers on examples anywhere else.
This fixes a problem with services that doesn't implement GetAll() for
one reason or another.

Lots of people been suggesting this. We still use MethodInvocation /
method_invocation for handling incoming method calls so use call()
instead of invoke_method() helps to separate the client and server
facilities. Which is a good thing(tm).
gunixcredentialsmessage.h ought to live with other UNIX headers,
and the credentials are moved from dbus-specific to just GIO sources.
Also move gfiledescriptorbased.c to the UNIX sources.
Things compile and the test-suite passes. Still need to hook up
gio.symbols and docs. There are still a bunch of TODOs left in the
sources that needs to be addressed.

Switch all users to the first style to avoid a crasher.
socket_strerror() was assuming all "strerror" messages are shorter
than 128 bytes, which is certainly true on Linux, but apparently not
on Windows.

The messages array was not reallocated correctly because it was using
malloc instead of realloc. Also, if the user requested messages but
none were received we would segfault. Rewrite the code to fix this
and, for better readability, use GPtrArray instead of rolling our own.
Also make the docs mention that the user need to free the returned
GSocketControlMessage objects using g_object_unref().
Clarify that *messages may be set to %NULL if there are no messages
(this will save pointless allocs of arrays).
Finally, the Win32 version didn't set messages to the expected value.

There are apparently two incompatible ways of naming abstract sockets:
pad the sockaddr with 0s and use the entire thing as the name, or else
don't, and just pass a shorter length value to the relevant functions.
We previously only supported the former method. Add support for the
latter.
Also correctly handle "anonymous" unix sockaddrs (eg, the client side
of a connection, or a socketpair() socket), and add unix domain socket
support to the socket-client and socket-server test programs to make
sure this all works.

Visual Studio doesn't like slash as directory separator, so use
backslash. While at it, sort the list of files put in the project file
just for clarity.
Gschema-compile uses glob which is available on Unix only. Thus can't
run the gschema-compile test except on Unix either.
To avoid an Automake error, comment out the SOURCES and LDADD of
unix-streams which for some reason has been commented out from
TEST_PROGS.
Can't use a Makefile.am target called foo_PROGRAMS for random files
that aren't actually programs, as Automake assumes EXEEXT should be
appended to the file names.
Correspond to GUnixInputStream and GUnixOutputStream. No true async
support though. But that is how the Win32 API is, for files not
explicitly opened for so-called overlapped IO.
The API to create these streams takes Win32 HANDLEs. Not file
descriptors, because file descriptors are specific to the C library
used. The user code and GLib might be using different C libraries.
Also add a test program for the new classes, and a gio-windows-2.0.pc
file.
- if a key becomes mandatory, drop it from the changeset

Define GStatBuf as the type used by g_stat() and g_lstat(). Replaces
the non-public struct tag _g_stat_struct. Mostly relevant for Windows
where there are several variants of stat-style structs. On POSIX, is
just another name for struct stat.
Actually, also on many POSIX systems there are in fact several
variants of struct stat and corresponding stat() and lstat()
functions, but as g_stat and g_lstat are normally on POSIX just macros
that expand to stat and lstat, this should not cause a problem. It's
only when it's the actual g_stat() or g_lstat() implementation inside
GLib that gets called that one needs to be sure the passed struct is
the same as what GLib expects.)
We need to check priv->cancelled after taking the lock. Previously we
only checked it just before taking the lock, which left a small chance
for a race.
Don't keep the lists of source files for libglib, libgobject and
libgio in the VS project files in addition to the canonical location,
the corresponding Makefile.am files.
Instead, generate the corresponding .vcproj files at make dist time
using the C preprocessor, from template files called .vcprojin. We
still list explicitly in the .vcprojin files some of the
Windows-specific source files, and the sources files of gnulib and
pcre.
