nspawn: make seccomp loading errors non-fatal
seccomp_load returns -EINVAL when seccomp support is not enabled in the
kernel [1]. This should be a debug log, not an error that interrupts nspawn.
If the seccomp filter can't be set and audit is enabled, the user will
get an error message anyway.

sysv-generator test: always log to console
Set $SYSTEMD_LOG_TARGET so that the output always goes to stdout/stderr. This
fixes running the test as root, as that logged to the journal previously.

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.

hwdb: add support for Alienware graphics amplifier
Unplugging and plugging in the cable will create various scancodes
on the keyboard controller.
Userspace within X should be able to interact with these to show
interesting messages. Assign them to generic prog1/prog2.
(David: add comment to hwdb explaining that these keycodes are reserved)

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.

Merge pull request #183 from ssahani/net
Improve tun/tap logging by using the new log_*errno*() functions that set 'errno' explicitly. Also fix a bunch of incorrect errno/r confusions.

Merge pull request #189 from teg/rtnl-rename
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.

udevd: event - don't log about failures of spawn processes when this is expected
PROGRAM and IMPORT{program} uses the exit code of the spawn process to decide if a rule matches or not,
a failing process is hence normal operation and not something we should warn about.
We still warn about other types of failing processes.
