This patch adds code to compile 'systemd-readahead-analyze' and install
it into $bindir.
Use this program to parse the contents of the readahead pack file, or
an arbitrary pack file and display which files are listed in it, and
how much of the files are requested to be readahead.
This code is not new - it's partially taken from sreadahead (formerly
maintained by Arjan van der Ven and me, and was originally written
by me), and adapted with the right bits to parse the systemd
readahead pack files, which are slightly different in format.
v2 adds a common READAHEAD_PACK_FILE_VERSION used in all the code
to provide a quick way to assure all these programs are always
synchronized. v3 fixes the integer math.

Only the main daemon process should be excluded from OOM handling,
not the worker processes or their child processes.

23mb to 5mb
Udev was the limiting factor for us on low-RAM systems.
Given an average RSS of 180kb, 128 workers would require ~23mb of RAM.
Now, please consider what happens when there is only, say, 15mb free.
Udev protects itself from OOM, and the kernel can do nothing but panic.
28 workers * 0.18mb = ~5mb. This change should not affect more powerful
systems much, given that they still get the addition from the amount of RAM.

This is a valid source entry in /etc/fstab:
//192.168.6.10/data /data cifs noperm,auto

Supposed to prevent creating unit files like:
├── dev-sda1.device.wants
│ └── .dot.mount -> /run/systemd/generator/.dot.mount
├── .dot.mount
from:
# cat /etc/fstab
/dev/sda1 /.dot vfat ro 1 3
which we later skip reading because of the leading '.'.

Trivial fix for:
src/login/logind-inhibit.h:37:3: error: redefinition of typedef 'InhibitWhat'
src/login/logind-inhibit.h:26:26: note: previous declaration of 'InhibitWhat' was here

This can invalidate otherwise valid source paths with trailing slashes,
such as "host:/" in the case of a network mount.
Based on a patch from Dave Reisner <dreisner@archlinux.org>, which
removed the slash mangling entirely.
Changed it to match on the leading slash to exclude non-path values.

This script will still run without the shebang, but we won't get the
intended effect of the errexit flag in the interpreter line.

Use the correct udev libexec dir as well, not systemd's.

can_sleep() returns a boolean, so a return value > 0 does not
mean 'na'.

Probably a copy-paste error, SYSTEMD_SLEEP_BINARY_PATH should
have been SYSTEMD_SLEEP_PATH.

This reverts commit 9b5af248f04b6cad8a5bca836e89a39e9f6823d9.
Udev now explicitely labels only files/directories in /dev. The selinux
array API is not released and will not work on other distros at this moment.

src/shared/util.c includes <sys/capability.h> but doesn't use anything
defined there. Since <sys/capability.h> is part of libcap, not libc,
don't require it.
Allows systemd-without-udevd to require fewer external libraries.

For now this only reads man: URLs, but later on we might want to support
info: too. http/https is probably out of focus.

systemd-udev is currently incorrectly labeling /run/udev/* content because it is
using selinux prefix labeling of /dev. This patch will allow systemd-udev to
use prefix labeling of /dev and /run.

MIMO USB displays use a generic VID/PID for the hub component. With a
bit of trickery we can detect them by the VID/PID of the graphics
component.
