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.

dbus-sysdeps-win: don't include wspiapi.h
This block provoked a warning on mingw-w64 because we were redefining

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.

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.
