Currently, DBus Specification only consists of four message types, so to
monitor all the types of message, no need to match all of them but just
left it empty is OK.

0d15a9035a Do not suggest user the next step after executed autogen.sh
We assume that user/developer who building dbus from source code are
familiar with the standard 'autogen.sh, configure, make, make install'
build process, so print such a notice doesn't make a lot of sense.

In addition, on *BSD platform, the pre-installed 'make' doesn't work at
all since gnu make is required. However, it named to 'gmake' on *BSD
platform. So the notice will makes new comer confused.

17fcbf4518 _dbus_read_credentials_socket: warn or fail at compile time if no support
On a whitelist of OSs known to have working credentials-passing
(currently FreeBSD, Linux, OpenBSD and NetBSD), it would be a
regression for us to not have credentials-passing, so fail hard.

On other OSs, raise a warning, which is not normally fatal but
will alert developers on those platforms.

4d869cf5c2 Remove BSD-style LOCAL_CREDS support
It appears that this regressed back in 2009 (commit 7bf132c7)
and doesn't compile. Also, with patches from Matt Fischer to make
it compile again on QNX, it compiles but doesn't actually work
on NetBSD, which was the platform for which this code was added.
This might be for the reasons described in
<http://julipedia.meroh.net/2006/08/localcreds-socket-credentials.html>.
NetBSD pkgsrc has a large unsubmitted patch to use LOCAL_PEEREID, which
is analogous to Linux/OpenBSD SO_PEERCRED.

So, I think we can safely assume that nobody is relying on this:
either they implement one of our many other supported
credentials-passing mechanisms, or they're patching it locally
anyway.

LOCAL_CREDS is not actually very good - it's awkward to use, and
doesn't provide the pid, only the uid. Of the platforms known to
implement it, QNX and NetBSD both have getpeereid() which provides
just as much information, while FreeBSD and Dragonfly BSD both have
SCM_CREDS which provides the pid too. So, let's just get rid of it.

b47d50623b Remove support for platforms with no 64-bit integer type
This has been a soft requirement since 1.5.0; anyone on such platforms
would have had to configure --without-64-bit, provoking a warning that
instructed them to report a D-Bus bug with details of their platform.
Nobody has done so, so if anyone still lacks a 64-bit integer type,
they're on their own.

(Also, I tried the build with --without-64-bit and it's full of
fatal compiler warnings, so it's not clear that we're actually
losing anything by removing this "feature".)

3b9c2817e9 dbus-sysdeps-win: don't include wspiapi.h
This block provoked a warning on mingw-w64 because we were redefining
_inline. According to Ralf's research, it was introduced in 452ff68a:
Windows 2000 doesn't have getaddrinfo and related functions in
ws2tcpip.h, but does have a shim implementation in wspiapi.h.

At the time of 452ff68a, mingw32 didn't have wspiapi.h, so it's unclear
why there was a __GNUC__ code path here. The "#define _inline" on that
code path looks likely to be some sort of workaround for a faulty version
of wspiapi.h? Current mingw-w64 does have wspiapi.h, so we enter the
__GNUC__ code path and get the redefinition.

dbus no longer supports Windows 2000, so we no longer need wspiapi.h
at all, and can rely on XP or later. (Ralf's policy is to only support
versions of Windows that are still supported by Microsoft, and Windows 2000
reached the end of its life-cycle in 2010.)

ee0f28f6a5 Use test binaries in build dir to do test
When do autolaunch testing, libdbus will try to start dbus-launch in
installed direcotry, if fail then fall back to dbus-launch in $PATH.
dbus-launch does a relative better thing to start dbus-daemon in build
directory, however, in most of case, the build $prefix is different from
the real prefix where dbus-daemon installed. So dbus-daemon will fail to
start due to can't find its config file. And then dbus-launch will fall
back to finally the installed dbus-daemon.

This patch fix this behavior and will start dbus-launch and dbus-daemon
in build directory in test environment.

8d2536e023 Remove obscure "low-latency" parts in the introduction of spec
According to Wikipedia
http://en.wikipedia.org/wiki/Latency_%28engineering%29#Packet-switched_networks
latency means "the time from the source sending a packet to the destination
receiving it". Therefore, latency is unrelated to whether the operation is
asynchronous or synchronous. And also unrelated to whether it's one-way or
round-trip. Latency exists for asynchronous and one-way transfer, because for
current DBus implementations we need at least one context switch to transfer
each message from the sender process to the receiver process. Emphasizing
D-Bus is low-latency could encourage user to abuse/misuse the system.
