Remove refcounting from DBusAuth and DBusAuthorization

Those structs are for DBusTransport internal use, they should not be
referenced outside it.
The transport needs only to allocate memory on initialization and free
it on finalization.
The lifecycle for the two allocated structs is DBusTransport lifecycle
and at DBusTransport's finalization its connection is already
disconnected.

Fix confusion between "is it authenticated?" and "try to authenticate"

Historically, _dbus_transport_get_is_authenticated() has had the
side-effect of trying to advance the authentication state machine (if
there's enough buffered input to do so). This seems an inappropriate
activity for what looks like a simple getter.

Split it into _dbus_transport_try_to_authenticate (which does what it
always used to do) and _dbus_transport_peek_is_authenticated (which
is the simple getter version).

To minimize the difference in behaviour for the stable branch of D-Bus,
I've only used _dbus_transport_peek_is_authenticated where it was used
in an assertion, which should clearly not have side effects (and I've
checked that the asserting function cannot be called until both
authentication and authorization have completed). Replacing most of the
calls to get_is_authenticated with try_to_authenticate is a possible
piece of future work.

Based on patches from Cosimo Alfarano, who noticed this
assertion-with-side-effects.

DBusString: fix may crash if try to free an uninitialized str

If the str will be freed hasn't been initialized by _dbus_string_init
correctly, _dbus_string_free may crash due to trying to free an
undefined memory.

Fix of cmake xmldoc dependencies chain.

This patch fixes an issues that xml documentation is generated on all builds regardless
if related files has been changed or not.

The patch adds a global xmldoc make target to which all generated html or man files are
added as build dependency. Each dependency itself depends on related CMakeLists.txt and
the xml file generated from the related xml.in file.

Always initialize threading before allocating a dynamic mutex

Dynamic allocation of mutexes can fail anyway, so this is easy.

Justification for not keeping the dummy mutex code-paths, even as an
opt-in thing for processes known to be high-performance and
single-threaded: real mutexes only cut the throughput of
test/dbus-daemon.c by a couple of percent on my laptop (from around
6700 to around 6600 messages per second), and libdbus crashes caused
by not calling dbus_threads_init_default() are sufficiently widespread
that they're wasting a lot of everyone's time.

Make taking a global lock automatically initialize locking if needed

This lets them be thread-safe by default, at the cost that they can
now fail.

init_uninitialized_locks() and init_global_locks() must now both
reimplement the equivalent of _dbus_register_shutdown_func(), by using
_dbus_platform_rmutex_lock() on the same underlying mutex around a call
to _dbus_register_shutdown_func_unlocked().

This is because if they used the usual _DBUS_LOCK() API (as
_dbus_register_shutdown_func() does), it would automatically try to
initialize global locking, leading to infinite recursion.
