tree-wide: fix memory leaks in users of bus_map_all_properties()
If you use bus_map_all_properties(), you must be aware that it might
touch output variables even though it may fail. This is, because we parse
many different bus-properties and cannot tell how to clean them up, in
case we fail deep down in the parser.
Fix all callers of bus_map_all_properties() to correctly cleanup any
context structures at all times.

Merge pull request #178 from utezduyar/man-sd_bus_message_get_creds
Improve the documentation of bus credentials by mentioning send-time metadata. This needs more love, we should really clarify metadata details here. However, this is still better than nothing, so it's fine.

Rename sd_rtnl to sd_netlink to prepare for further netlink-protocol support. Anything rtnl specific still uses the sd_rtnl prefix, but the generic parts (including the bus and message objects) are now called sd_netlink.

networkd: create "kernel" setting for IPForwarding
In 5a8bcb674f71a20e95df55319b34c556638378ce, IPForwarding was introduced
to set forwarding flags on interfaces in .network files. networkd sets
forwarding options regardless of the previous setting, even if it was
set by e.g. sysctl. This commit creates a new option for IPForwarding,
"kernel", that preserves the sysctl settings rather than always setting
them.
See https://bugs.freedesktop.org/show_bug.cgi?id=89509 for the initial
bug report.

kmod-setup: don't print warning on -ENOSYS
-ENOSYS is returned from kmod_module_probe_insert_module() if a module isn't
available, not -ENOENT. Don't spit out a warning in that case unless the
warn_if_unavailable flag is set.
Also factor out the condition into an own variable for better readability.
ima_write_policy() expects data to be written as one or more
rules, no more than PAGE_SIZE at a time. Easiest way to ensure
that we are not splitting rules is to read and write one line at
a time.

core: Let two more booleans survive a daemon-reload
Without the boolean bus_name_good services as well as cgroup_realized
for units a unit of Type=dbus and ExecReload sending SIGHUP to $MAINPID
will be terminated if systemd will be daemon reloaded.
Unfortunately, gcc keeps warning about those even when we use an
explicit (void) cast to indicate we are not interested in the result.
LLVM's clang does not have that issue and works fine with the casts.
GCC bug being tracked at:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66425
Until that GCC bug is fixed (and the version with the fix is in
many/most distributions) or we switch to LLVM as the default compiler,
it looks like we'll have to disable this warning by default...
Tested by building files known to present warnings about unused results
without the suppression, confirmed that the warnings were no longer
present with this patch applied.
This partially reverts commit 00c11bc53a1d37 ("build-sys: don't suppress irrelevant warnings").
journald: do not strip leading whitespace from messages
Keep leading whitespace for compatibility with older syslog
implementations. Also useful when piping formatted output to the
`logger` command. Keep removing trailing whitespace.
Tested with `pstree | logger` and checking that the output of
`journalctl | tail` included aligned and formatted output.
Confirmed that all test cases still pass as expected.

build-sys: make man/systemd.directives.xml depend on man/custom-entities.ent
Currently, the following command sequence fails:
make distclean
./autogen.sh c
make distcheck
That's because the command invoked to build man/systemd.directives.xml needs
man/custom-entities.ent to function, which itself isn't a dependency.
The $(filter-out $<,$^) logic used to filter out everything from the
prerequisites except for the first word, which doesn't work anymore

bus: fix pattern matching
DBus-spec defines two different pattern matchings:
1) Path and namespace prefix matching. In this case, A matches B either
if both are equal, or if B is fully included in the namespace of A.
In other words, A has to be a prefix of B, but end with a separator
character (or the following character in B must be one).
This is used for path_namespace= and arg0namespace=
2) The other pattern matching is used for arg0path= which does a two-way
matching. That is, A must be a prefix of B, or B a prefix of A.
Furthermore, the prefix must end with a separator.
Fix the sd-bus helpers to reflect that. The 'simple_' and 'complex_'
prefixes don't make any sense now, but.. eh..

bus: fix arg0path= two-way matching
DBus spec clearly defines arg0path= to be a two-way matching. That is,
either the matcher or the matchee can be a prefix of the other to match.
This is not possible to implement with bloom-filters. Instead, we'd have
to add a separate filter for each prefix. This is non-trivial, though.
Hence, just skip the match for now and match locally.

bus: fix bloom_add_prefixes() to add all required data
Lets look at an example where we add arg0="/foo/bar/waldo" to a
bloom-filter. The following strings are added:
"arg0:/foo/bar/waldo"
"arg0-slash-prefix:/foo/bar"
"arg0-slash-prefix:/foo"
Two problems arise:
1) If we match on "arg0path=/foo/bar/waldo", the dbus-spec explicitly
states that equal strings are also considered prefixes. However, in the
bloom-match, we can only provide a single match-filter. Therefore, we have
to add "arg0-slash-prefix:/foo/bar/waldo" there, but this never occured in
the bloom-mask of the message.
Hence, this patch makes sure bloom_add_prefixes() adds the full path as
prefix, too.
2) If we match on "arg0path=/foo/", the dbus-spec states that arg0path
does prefix-matching with the trailing slash _included_, unlike
path_namespace= matches, which does *not* include them. This is
inconsistent, but we have to support the specs. Therefore, we must add
prefixes with _and_ without trailing separators.
Hence, this patch makes sure bloom_add_prefixes() adds all prefixes with
the trailing slash included.
The final set of strings added therefore is:
"arg0:/foo/bar/waldo"
"arg0-slash-prefix:/foo/bar/waldo"
"arg0-slash-prefix:/foo/bar/"
"arg0-slash-prefix:/foo/bar"
"arg0-slash-prefix:/foo/"
"arg0-slash-prefix:/foo"
"arg0-slash-prefix:/"
