dbus-launch: if using X to define the session lifetime, do not poll stdin
dbus-launch --exit-with-session attempts to scope the session length
to various things:
- if DISPLAY points to an X server, exit when the X session ends
- if stdin is a terminal, exit when end-of-file is reached
- if both are true, exit when one of them happens, whichever is first
- if neither is true, fail
These are not particularly useful semantics: if the session is scoped to
the X session, then the terminal from which dbus-launch was launched
is irrelevant. This also causes practical problems when dbus-launch
consumes characters from the terminal from which it happens to have
been launched (some display managers, like slim and nodm, run users' X
sessions with stdin pointing to the terminal from which the init daemon
happens to have started the display manager during boot, usually tty1
on Linux).

transport: add new unixexec transport on Unix
The "unixexec:" transport will create a local AF_UNIX socket with
socketpair(), then fork and execute a binary on one side with STDIN and
STDOUT connected to it and then use the other side.
This is useful to implement D-Bus tunneling schemes, for example to get
a D-Bus connection to the system bus on a different host, similar how
udisks is already doing it. (udisks uses SSH TCP tunneling for this,
which is a bit ugly and less secure than this solution).
Suggested use is with connection strings like the following:
unixexec:path=ssh,argv1=foobar,argv2=system-bus-bridge
or:
unixexec:path=pkexec,argv1=system-bus-bridge
or even:
unixexec:path=sudo,argv1=system-bus-bridge
The first line would execute the binary 'system-bus-bridge' on host
'foobar' and then pass D-Bus traffic to it. This (hypothetical) bridge
binary would then forward the information to the local system bus.
The second and third line use this scheme locally to acquire a
privileged connection through pkexec resp. sudo: instead of connecting
directly to the bus, they use the same bridge binary which will forward
all information to the system bus.
The arguments of the protocol are 'path' for the first execlp()
argument, and argv0, argv1, and so on for the following arguments. argv0
can be left out in which case path will be used.

Never use non-libdbus threading primitives
This lets us simplify considerably, by assuming that we always have both
recursive and suitable-for-condition-variable mutexes.
The Windows implementation has been compiled (on 32-bit mingw-w64)
but not tested. Justification for the approach used on Windows,
and in particular, using the existing "non-recursive" locks as if
they were recursive:
* We've been using them in conjunction with condition variables all
along, so they'd better be suitable
* On fd.o #36204, Ralf points out that mutexes created via CreateMutex
are, in fact, recursive
* Havoc's admonitions about requiring "Java-style" recursive locking
(waiting for a condition variable while holding a recursive lock
requires releasing that lock n times) turn out not to apply to
either of our uses of DBusCondVar in DBusConnection, because the
lock is only held for a short time, without calling into user code;
indeed, our Unix implementation isn't recursive anyway, so if
the Windows implementation reaches the deadlocking situation
somehow (waiting for condition variable while locked more than once),
the Unix implementation would already have deadlocked on the same
code path (trying to lock more than once)
One possible alternative to a CreateMutex mutex for use with condition
variables would be a CRITICAL_SECTION. I'm not going to implement this,
but Windows developers are welcome to do so.

Distinguish between two flavours of mutex
dbus-threads.h warns that recursive pthreads mutexes are not compatible
with our expectations for condition variables. However, the only two
condition variables we actually use only have their corresponding
mutexes locked briefly (and we don't call out to user code from there),
so the mutexes don't need to be recursive anyway. That's just as well,
because it turns out our implementation of recursive mutexes on
pthreads is broken!
The goal here is to be able to distinguish between "cmutexes" (mutexes
compatible with a condition variable) and "rmutexes" (mutexes which
are recursive if possible, to avoid deadlocking if we hold them while
calling user code).
This is complicated by the fact that callers are not guaranteed to have
provided us with both versions of mutexes, so we might have to implement
one by using the other (in particular, DBusRMutex *aims to be*
recursive, it is not *guaranteed to be* recursive).

dbus-protocol.h: compile under C++11
C++11 compilers have a feature called 'user-defined string literals' which
allow arbitrary string suffixes to have user-defined meaning.
This makes code that concatenates macros with string literals without
intervening whitespace illegal under C++11. Fortunately, string literal
concatenation has allowed intervening whitespace since the dawn of time,
so the solution is to simply pad with spaces.
Tested (header) with GCC 4.7 (trunk).
