95ed3294c6 Move handling of sysv initscripts to a generator
Reuses logic from service.c and the rc-local generator.

Note that this drops reading of chkconfig entirely. It also drops reading
runlevels from the LSB headers. The runlevels were only used to check for
runlevels outside of the normal 1-5 range and then add special dependencies
and settings. Special runlevels were dropped in the past so it seemed to be
unused code.

The generator does not know about non-generated units with a value set with
SysVStartPriority=. These are therefor not taken into account when converting
start priority to before/after.

e0dd92729e shared: add ring buffer
New "struct ring" object that implements a basic ring buffer for arbitrary
byte-streams. A new basic runtime test is also added.

This will be needed for our pty helpers for systemd-console and friends.

65b3903ff5 journal: guarantee async-signal-safety in sd_journald_sendv
signal(7) provides a list of functions which may be called from a
signal handler. Other functions, which only call those functions and
don't access global memory and are reentrant are also safe.
sd_j_sendv was mostly OK, but would call mkostemp and writev in a
fallback path, which are unsafe.

Being able to call sd_j_sendv in a async-signal-safe way is important
because it allows it be used in signal handlers.

Safety is achieved by replacing mkostemp with open(O_TMPFILE) and an
open-coded writev replacement which uses write. Unfortunately,
O_TMPFILE is only available on kernels >= 3.11. When O_TMPFILE is
unavailable, an open-coded mkostemp is used.

0bba8d6eb7 build-sys: merge libsystemd-login into libsystemd
A compatibility libsystemd-login library is created which uses
.symver and ifunc magic proposed by Lennart to make programs linked
to the old library name continue to work seamlessly.

Unfortunately the bfd linker crashes:
  https://sourceware.org/bugzilla/show_bug.cgi?id=16467
This will be fixed in binutils 2.25.

As a work-around, gold can be used:
  LDFLAGS=-Wl,-fuse-ld=gold

Unfortunately the switch to pick the linker appeared in gcc 4.8.

This also doesn't work with LLVM:

ccd06097c7 Use format patterns for usec_t, pid_t, nsec_t, usec_t
It is nicer to predefine patterns using configure time check instead of
using casts everywhere.

Since we do not need to use any flags, include "%" in the format instead
of excluding it like PRI* macros.

294c866023 Add bus-driverd
systemd-bus-driverd is a small daemon that connects to kdbus and
implements the org.freedesktop.DBus interface. IOW, it provides the bus
functions  traditionally taken care for by dbus-daemon.

Calls are proxied to kdbus, either via libsystemd-bus (were applicable)
or with the open-coded use of ioctl().

Note that the implementation is not yet finished as the functions to
add and remove matches and to start services by name are still missing.

5b12334d35 bus: add new sd_bus_creds object to encapsulate process credentials
This way we can unify handling of credentials that are attached to
messages, or can be queried for bus name owners or connection peers.

This also adds the ability to extend incomplete credential information
with data from /proc,

Also, provide a convenience call that will automatically determine the
most appropriate credential object for an incoming message, by using the
the attached information if possible, the sending name information if
available and otherwise the peer's credentials.

f1e0c18340 build-sys: add a link test for exported symbols
I know that this is a pretty big net to catch some small fish,
but we *do* regularly forget to properly export symbols that
were supposed to be exported.

This time sd_bus_get_current and some renamed symbols are caught.

f579559b3a networkd: add a basic network daemon
This daemon listens for and configures network devices tagged with
'systemd-networkd'. By default, no devices are tagged so this daemon
can safely run in parallel with existing network daemons/scripts.

Networks are configured in /etc/systemd/network/*.network. The first .network
file that matches a given link is applied. The matching logic is similar to
the one for .link files, but additionally supports matching on interface name.

The mid-term aim is to provide an alternative to ad-hoc scripts currently used
in initrd's and for wired setups that don't change much (e.g., as seen on
servers/and some embedded systems).

Currently, static addresses and a gateway can be configured.

Example .network file:

[Match]
Name=wlp2s0

[Network]
Description=My Network
Gateway=192.168.1.1
Address=192.168.1.23/24
Address=fe80::9aee:94ff:fe3f:c618/64

96c374d0a5 socket-proxyd: rename from saproxy
The thing is a daemon, hence needs a "d" prefix. Also, we tend to not
abbreviate names of background components unnecessarily, since they are
not primary commands people type. Then, the fact that this thing does
socket actviation is mostly in implementationd detail for the proxy.

Also, do some minor indenting clean-ups and other code updates.

fd38203a2a bus: add minimal event loop API
So far we tried to use epoll directly wherever we needed an event loop.
However, that has various shortcomings, such as the inability to handle
larger amounts of timers (since each timerfd costs one fd, which is a
very limited resource, usually bounded to 1024), and inability to do
priorisation between multiple queued events.

Let's add a minimal event loop API around epoll that is suitable for
implementation of our own daemons and maybe one day can become public
API for those who desire it.

This loop is part of libsystemd-bus, but may be used independently of
it.

29ddb38fea libsystemd-bus: add lightweight object vtable implementation for exposing objects on the bus
This adds a lightweight scheme how to define interfaces in static fixed
arrays which then can be easily registered on a bus connection. This
makes it much easier to write bus services.

This automatically handles implementation of the Properties,
ObjectManager, and Introspection bus interfaces.

c51d84dc09 support acpi firmware performance data (FPDT)
Prefer firmware-provided performance data over loader-exported ones; if
ACPI data is available, always use it, otherwise try to read the loader
data.

The firmware-provided variables start at the time the first EFI image
is executed and end when the operating system exits the boot services;
the (loader) time calculated in systemd-analyze increases.

8f6ce71fe7 device-nodes: move device node specific code to own file
In the process, rename udev_encode_string which is poorly named for what
it does. It deals specifically with encoding names that udev creates and
has its own rules: utf8 is valid but some ascii is not (e.g. path
separators), and everything else is simply escaped. Rename it to
encode_devnode_name.

merging of these two in the future.

3731acf1ac backlight: add minimal tool to save/restore screen brightness across reboots
As many laptops don't save/restore screen brightness across reboots,
let's do this in systemd with a minimal tool, that restores the
brightness as early as possible, and saves it as late as possible. This
will cover consoles and graphical logins, but graphical desktops should
do their own per-user stuff probably.

This only touches firmware brightness controls for now.

1a14a53cfd gpt-auto-generator: add basic auto-discovery of GPT partitions
This adds a simple generator that is capable of automatically
discovering certain GPT partitions by their type UUID and mount/enable
them. This currently covers swap partitions and /home partitions, but is
expected to grow more features soon.

This currently doesn't handle LUKS encrypted /home.

This enables all swap partitions of type
0657fd6da4ab43c484e50933c84b4f4f, if found.

This mounts the first partition of type 933ac7e12eb44f13b8440e14e2aef915
as /home, if it is found.
