core: convert PID 1 to libsystemd-bus
This patch converts PID 1 to libsystemd-bus and thus drops the dependency on libdbus. The only remaining code using libdbus is a test case that validates our bus marshalling against libdbus' marshalling, and this dependency can be turned off. This patch also adds a couple of things to libsystem-bus, that are necessary to make the port work: - Synthesizing of "Disconnected" messages when bus connections are severed. - Support for attaching multiple vtables for the same interface on the same path. This patch also fixes the SetDefaultTarget() and GetDefaultTarget() bus calls which used an inappropriate signature. As a side effect we will now generate PropertiesChanged messages which carry property contents, rather than just invalidation information.

Features:
+* sd-event: allow multiple signal handlers per signal
+
+* timer: expose accuracy as unit setting
+
+* sd-event: do per-minute coalescing of timer events too
+
+* when we detect low battery and no AC on boot, show pretty splash and refuse boot
+
+* move libasyncns into systemd as libsystemd-asyncns
+
+* calendarspec: support value ranges with ".." notation. Example: 2013-4..8-1
+
+* pid1 porting:
+ - restore selinux access control on properties
+
+* sd-bus: when triggering property change events, allow a NULL strv indicate that all properties listed as such are send out as changed
+
+* sd-bus: enforce signatures on response messages
+
+* sd-bus: make message handlers take an sd_bus_error and generate error replies automatically if they are set
+
+* sd-bus: when replying to a bus message we should not need to specify the bus again
+
+* sd-bus: see if we can drop more message validation on the sending side
+
+* sd-bus: introduce sd_bus_creds object and attach it to messages as well as allow querying it for names
+
+* sd-bus: support "const" properties as flag
+
+* sd-bus: add api call to escape bus path components
+
+* sd-event: when a handler returns an error, just turn off its event
+ source, but do not return anything up to the event loop
+ caller. Instead add parameter to sd_event_request_quit() to take
+ retval. This way errors rippling upwards are the option, not the
+ default
+
+* sd-event: child pid handling: first invoke waitid(WNOHANG) and call event handler, only afterwards reap the process
+
+* sd-event: native support for watchdog stuff
+
+* machined, localed: when we try to kill an empty cgroup, generate an ESRCH call over the bus
+
+* sd-bus: SD_BUS_COMMENT() macro for inclusion in vtables, syntax inspired by gdbus
+
+* libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
+
* be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
* check :no-sender logic after PID 1 conversion
