event: rework sd-event exit logic
With this change a failing event source handler will not cause the
entire event loop to fail. Instead, we just disable the specific event
source, log a message at debug level and go on.
This also introduces a new concept of "exit code" which can be stored in
the event loop and is returned by sd_event_loop(). We also rename "quit"
to "exit" everywhere else.
Altogether this should make things more robus and keep errors local
while still providing a way to return event loop errors in a clear way.

parts of systemd.
gpt-auto-generator.c:
scan-build could not find blkid.h. Whether it should be blkid.h or
blkid/blkid.h seems to depend on the version used. We already use
blkid/blkid.h in udev-builtin-blkid.c so it seems safe to use that
here too.
Makefile.am:
Moved some -D's from CFLAGS to CPPFLAGS. I also simplified them a
bit and got rid of a left over DBUS_CFLAGS.
test-cgroup-mask.c/test-sched-prio.c
A variable was added to store the replaced TEST_DIR. When wrapped
in an assert_se TEST_DIR was not replaced in the logged error.
While not an issue introduced in this patch we might as well fix
it up while we are here.

bus: when we _unref() a NULL pointer, don't use assert_return()
We support unreffing NULL pointers just fine and we shouldn't pay the
_unlikely_() price for it, not get a debug message if we do, hence let's
not use assert_return() here.

This reverts commit
f7e2bd5a8070ba86cba6bcbf7d1c9a8173d846d4.
Most of these checks are not programming errors, but happen during
normal runtime. For example bus_kernel_pop_memfd() is called all the
time on non-kdbus systems and is supposed to quickly fail if kdbus is
not available. However, assert_return() makes this failure
expensive, and hence has no place here. With the most recent change to
assert_return() it will even log a debug message, which should never
happen here.

We really should let the dependency logic add jobs for dependencies here
rather than manually adding in jobs, overtaping the real problem.
