I have some strange issues with irqbalance sometimes overwritin
smp_affinity values for banned/ignored IRQs. The issue is reproduceable
and is mitigated when I change theway how the irqbalance command line is
built. The only difference between the resulting command is that there
is only one space between the -t parameter and the first -i parameter
value.

Allow the user to specify the level at which irqbalance assumes the cache
domains are partitioned. Keep the default value of 2.

Upstream has finally patched the UI communication socket
creation to happen only if the irqbalance UI is enabled.
As we do not use the irqbalance UI, we can remove
our local fix implemented by 4f0c847828.
(If you want to enable irqbalance UI, the fix is still needed.)

Irqbalance defines /run/irqbalance dir for its socket
communication between irqbalance and its UI. /run does not exist
in OpenWrt (although it is defined by the Linux FHS), so the
socket creation fails. Although we do not compile UI and thus
the issue is not critical to us, fix the directory location.
Additionally, the creation is originally handled by a systemd
init script that we do not use.
* patch source to define dir as /var/run/irqbalance
* create the dir in the procd init script.

Added support for reload_config
This service does not need to start so early (even
before the netwrok is up). Start it after
the device is mostly up and operational.

Added the ability to change sampling interval
and provide a list of IRQ's to ignore
via /etc/config/irqbalance

Add support for uci config file.
Only a global 'enabled" switch has been implemented so far.
* Default config disables irqbalance initially, so that there is
no change with the previous behaviour (and the possibly existing
separate launch scripts in people's builds).
Config file and init script can be later extended for irqbalance
options like the oneshot mode or the evaluation interval
(Also change the init file to use tabs)
