Enhance systemd-networkd to be able to control a CAN device's berr-reporting
flag via the new boolean directive BusErrorReporting= to be used in network
files.
While we don't support prefix being != /usr, and this is hardcoded
all over the place, variables in pkg-config file are expected
to have overridable base directory.
This is important for at least the following two use cases:
- Installing projects to non-FHS package-specific prefixes for Nix-style
package managers. Of course, it is then their responsibility
to ensure systemd can find the service files.
- Installing to local path for development purposes.
This is a compromise between running a program from a build directory,
and running it fully installed to system prefix.
You will not want to write to system prefix in either case.

Partially reverts 6e65df89c3
commit 15d7ab87c4 introduced the
change to add an 'alias' state, but it was wired to systemctl
only when running in 'client-side' mode. Return success as
expected and documented also when running in 'server-mode'.

This uses GREEDY_ALLOC_ROUND_UP() to grow the allocation size
exponentially. This should speed allocation loops up a bit, given
that we often call strextend() repeatedly in a loop on the same
buffer.
Previously, dns_answer_add() was O(n^2).
With this change dns_packet_extract() becomes ~15 times faster for some
extremal case.

We already handle foreign routing policy rules correctly by the previous
commit. So, the serialization/deserialization of rules are not necessary
anymore.
networkd already drop foreign address, routes, and nexthops on startup,
except those created by kernel. However, previously, routing policy
rules were not. The logic of serialization/deserialization of rules only
works for rules created by previous invocation of networkd, and does not
work for one created by other tools like `ip rule`.
This makes networkd drop foreign routing policy rules except created by
kernel on startup. Also, remove rules created by networkd when the
corresponding links are dropped or networkd is stopping.
When compiling with CFLAGS='-Werror=maybe-uninitialized -Og' we get a
warning about uninitialized "next_timeout" variable.
Avoid the warning by adding an (unreachable) "default" label.

In situations where a service fails to start, systemd suggests the user to
use "journalctl -xe" to get details about the failure. While running this
command does provide some additional details, most of the information is
similar to what was already printed when the service fails.
often the actual reason for the failure can be found in the logs of the
service that fails to start.
This patch updates the wording to suggest using "-u" to view the service
logs instead.

This commit adds support for disabling the read and write
workqueues with the new crypttab options no-read-workqueue
and no-write-workqueue. These correspond to the cryptsetup
options --perf-no_read_workqueue and --perf-no_write_workqueue
respectively.
cdrom_id udev helper does not parse all MMC profiles. Following change
fixes this issue and parse all 34 profiles from all MMC standard versions.
Also it replaces magic constants by macros provided by linux/cdrom.h and
fixes cd_profiles_old_mmc() to issue READ_DISC_INFO command in two steps,
like it is doing kernel and also mkudffs.
