TuneD is listening on paths specified in config in option unix_socket_paths and send signals to paths in option unix_socket_signal_paths.
Example call:
printf '[{"jsonrpc": "2.0", "method": "active_profile", "id": 1}, 1]' | sudo nc -U /run/tuned/tuned.sock
printf '{"jsonrpc": "2.0", "method": "switch_profile", "params": {"profile_name": "balanced"}, "id": 1}' | sudo nc -U /run/tuned/tuned.sock
This PR also introduce possibility to disable dbus API in main TuneD config.

When the reapply_sysctl option in tuned-main.conf is set to 1, "system"
sysctls from /run/sysctl.d/*.conf, /etc/sysctl.d/*.conf and
/etc/sysctl.conf will be set *after* TuneD sysctl settings are applied.
As reapply_sysctl=1 is TuneD default, this can be confusing to TuneD
users who only rely on TuneD profile settings and do not know about this
functionality. We also need a way to inform other components using
TuneD about this.
This PR adds information about reapplied sysctls in TuneD logs.

Extends the runtime API by the method:
instance_acquire_devices(devices, instance_name)
E.g. consider the following TuneD profile:
[cpus_perf]
type=cpu
devices=cpu0, cpu1
governor=performance
[cpus_idle]
type=cpu
devices=${f:cpulist2devs:2-3}
governor=ondemand
[cpus_idle2]
type=cpu
devices=${f:cpulist2devs:4-5,7}
governor=ondemand
Notice that it's possible to use internal function 'cpulist2devs' to easily
specify cpulists.
After the following API call:
instance_acquire_devices("cpulist:2-5,7", "cpus_perf")
It will result in cpu0 - cpu5 and cpu7 having the "performance" governor.
It's also possible to specify full device names in the API instead of the
cpulist, e.g.:
instance_acquire_devices("cpu2,cpu3,cpu4,cpu5,cpu7", "cpus_perf")
In case the comma is part of the device name, it can be escaped by "\,".
In case the device name starts with the string "cpulist:", e.g. there is
by accident device named "cpulist:abcd", it's possible to use
"cpulist:cpulist:abcd" to escape it and don't recognize it as the cpulist.
The cpulist expand feature also supports bitmasks variant prefixed by the
0x and written as a string, e.g. "0xffffffff", i.e. all the standard
TuneD cpulist syntaxes are supported.

Now it should allow duplicate options and sections in the INI files, the
latest value is taken, the previous values are ignored, e.g.:
[selinux]
avc_cache_threshold=4096
avc_cache_threshold=8192
The avc_cache_threshold will be set to the 8192.

The new profile sets the intel_acpi driver to passive mode to
be able to set the standard acpi governors (ondemand/userspace)
and provides more flexibility on the C-states, as it is exposed
as a new variable.
