When resolving /dev/console one would often get "tty0" meaning the active VT.
Resolving to the actual tty (e.g. "tty1") will notably help on boot when
determining whether or not PID1 can output to the console.
reboot syscall can be performed with an additional argument. In some
systems this functionality can be useful to modify the mode of the
next boot performed by the bootloader.
To write useful bus code clients need to validate utf8 frequently since
the bus reacts allergic to it. Since glibc does not provide any calls
for this, let's provide it as part of libsystemd-bus.
This also drops --ignore-env, which can't really work anymore if we
allow multiple fds. Also adds support for pretty printing of peer
identities for debug purposes, and abstract namespace UNIX sockets. Also
ensures that we never take more connections than a certain limit.
Instead of individually checking for containers in each user do this
once in a new call proc_cmdline() that read the file only if we are not
in a container.
After all, we ended up calling detect_container() more often than
detect_virtualization(), hence the former one should cache the results,
since the latter is only a wrapper around the former.
This introduces a new key NamePolicy, which takes an ordered list of naming
policies. The first successful one is applide. If all fail the value of Name
(if any) is used.
The possible policies are 'onboard', 'slot', 'path' and 'mac'.
This patch introduces a default link file, which replaces the equivalent udev
rule.

-Og Optimize debugging experience. -Og enables optimizations that do
not interfere with debugging. It should be the optimization level of
choice for the standard edit-compile-debug cycle, offering a
reasonable level of optimization while maintaining fast compilation
and a good debugging experience.
Messages with log levels above the current maximum log level will be dropped
inside log_meta(). But to be able to call the function, all parameters for
the function need to be provided. This can easily get expensive, if values
need to be calculated or functions are used in parameters.
Avoid all useless work by checking inside the macro, before we look
at any parameters passed to the logging functions.
