Luca Boccassi 65224c1d0e core: rename ShutdownWatchdogSec to RebootWatchdogSec
This option is only used on reboot, not on other types of shutdown
modes, so it is misleading.
Keep the old name working for backward compatibility, but remove it
from the documentation.

Luca Boccassi acafd7d8a6 core: add KExecWatchdogSec option
Rather than always enabling the shutdown WD on kexec, which might be
dangerous in case the kernel driver and/or the hardware implementation
does not reset the wd on kexec, add a new timer, disabled by default,
to let users optionally enable the shutdown WD on kexec separately
from the runtime and reboot ones. Advise in the documentation to
also use the runtime WD in conjunction with it.

Fixes: a637d0f9ec ("core: set shutdown watchdog on kexec too")

Michal Sekletar b070c7c0e1 core: introduce NUMAPolicy and NUMAMask options
Make possible to set NUMA allocation policy for manager. Manager's
policy is by default inherited to all forked off processes. However, it
is possible to override the policy on per-service basis. Currently we
support, these policies: default, prefer, bind, interleave, local.
See man 2 set_mempolicy for details on each policy.

Overall NUMA policy actually consists of two parts. Policy itself and
bitmask representing NUMA nodes where is policy effective. Node mask can
be specified using related option, NUMAMask. Default mask can be
overwritten on per-service level.

Jan Klötzke dc653bf487 service: handle abort stops with dedicated timeout
When shooting down a service with SIGABRT the user might want to have a
much longer stop timeout than on regular stops/shutdowns. Especially in
the face of short stop timeouts the time might not be sufficient to
write huge core dumps before the service is killed.

This commit adds a dedicated (Default)TimeoutAbortSec= timer that is
used when stopping a service via SIGABRT. In all other cases the
existing TimeoutStopSec= is used. The timer value is unset by default
to skip the special handling and use TimeoutStopSec= for state
'stop-watchdog' to keep the old behaviour.

If the service is in state 'stop-watchdog' and the service should be
stopped explicitly we still go to 'stop-sigterm' and re-apply the usual
TimeoutStopSec= timeout.

Lennart Poettering 143fadf369 core: remove JoinControllers= configuration setting
This removes the ability to configure which cgroup controllers to mount
together. Instead, we'll now hardcode that "cpu" and "cpuacct" are
mounted together as well as "net_cls" and "net_prio".

The concept of mounting controllers together has no future as it does
not exist to cgroupsv2. Moreover, the current logic is systematically
broken, as revealed by the discussions in #10507. Also, we surveyed Red
Hat customers and couldn't find a single user of the concept (which
isn't particularly surprising, as it is broken...)

This reduced the (already way too complex) cgroup handling for us, since
we now know whenever we make a change to a cgroup for one controller to
which other controllers it applies.

Zbigniew Jędrzejewski-Szmek 444d586333 meson: add -Dmemory-accounting-default=true|false
This makes it easy to set the default for distributions and users which want to
default to off because they primarily use older kernels.
