c2fc2c2560 units: increase watchdog timeout to 3min for all our services
Apparently, disk IO issues are more frequent than we hope, and 1min
waiting for disk IO happens, so let's increase the watchdog timeout a
bit, for all our services.

See #1353 for an example where this triggers.

a24111cea6 Revert "units: add SecureBits"
This reverts commit 6a716208b3.

Apparently this doesn't work.

6a716208b3 units: add SecureBits
No setuid programs are expected to be executed, so add
SecureBits=noroot noroot-locked
to unit files.

1b8689f949 core: rename ReadOnlySystem= to ProtectSystem= and add a third value for also mounting /etc read-only
Also, rename ProtectedHome= to ProtectHome=, to simplify things a bit.

With this in place we now have two neat options ProtectSystem= and
ProtectHome= for protecting the OS itself (and optionally its
configuration), and for protecting the user's data.

417116f234 core: add new ReadOnlySystem= and ProtectedHome= settings for service units
ReadOnlySystem= uses fs namespaces to mount /usr and /boot read-only for
a service.

ProtectedHome= uses fs namespaces to mount /home and /run/user
inaccessible or read-only for a service.

This patch also enables these settings for all our long-running services.

Together they should be good building block for a minimal service
sandbox, removing the ability for services to modify the operating
system or access the user's private data.

40393d5247 units: remove CAP_SYS_PTRACE capability from hostnamed/networkd
The ptrace capability was only necessary to detect virtualizations
environments. Since we changed the logic to determine this to not
require priviliges, there's no need to carry the CAP_SYS_PTRACE
capability anymore.

cde93897cd event: hook up sd-event with the service watchdog logic
Adds a new call sd_event_set_watchdog() that can be used to hook up the
event loop with the watchdog supervision logic of systemd. If enabled
and $WATCHDOG_USEC is set the event loop will ping the invoking systemd
daemon right after coming back from epoll_wait() but not more often than
$WATCHDOG_USEC/4. The epoll_wait() will sleep no longer than
$WATCHDOG_USEC/4*3, to make sure the service manager is called in time.

This means that setting WatchdogSec= in a .service file and calling
sd_event_set_watchdog() in your daemon is enough to hook it up with the
watchdog logic.

49dbfa7b2b units: introduce new Documentation= field and make use of it everywhere
This should help making the boot process a bit easier to explore and
understand for the administrator. The simple idea is that "systemctl
status" now shows a link to documentation alongside the other status and
decriptionary information of a service.

This patch adds the necessary fields to all our shipped units if we have
proper documentation for them.

5430f7f2bc relicense to LGPLv2.1 (with exceptions)
We finally got the OK from all contributors with non-trivial commits to
relicense systemd from GPL2+ to LGPL2.1+.

Some udev bits continue to be GPL2+ for now, but we are looking into
relicensing them too, to allow free copy/paste of all code within
systemd.

The bits that used to be MIT continue to be MIT.

The big benefit of the relicensing is that closed source code may now
link against libsystemd-login.so and friends.
