OpenWrt uses a lot of (b)ash scripts for initial setup. This isn't the
best solution as they almost never consider syncing files / data. Still
this is what we have and we need to try living with it.
Without proper syncing OpenWrt can easily get into an inconsistent state
on power cut. It's because:
1. Actual (flash) inode and data writes are not synchronized
2. Data writeback can take up to 30 seconds (dirty_expire_centisecs)
3. ubifs adds extra 5 seconds (dirty_writeback_centisecs) "delay"
Some possible cases (examples) for new files:
1. Power cut during 5 seconds after write() can result in all data loss
2. Power cut happening between 5 and 35 seconds after write() can result
in empty file (inode flushed after 5 seconds, data flush queued)
Above affects e.g. uci-defaults. After executing some migration script
it may get deleted (whited out) without generated data getting actually
written. Power cut will result in missing data and deleted file.
There are three ways of dealing with that:
1. Rewriting all user-space init to proper C with syncs
2. Trying bash hacks (like creating tmp files & moving them)
3. Adding sync and hoping for no power cut during critical section
This change introduces the last solution that is the simplest. It
reduces time during which things may go wrong from ~35 seconds to
probably less than a second. Of course it applies only to IO operations
performed before /etc/init.d/boot . It's probably the stage when the
most new files get created.
All later changes are usually done using smarter C apps (e.g. busybox or
uci) that creates tmp files and uses rename() that is expected to be
atomic.

The following command checks if a instance of a service is running.
/etc/init.d/<service> running <instance>
In the variable `$@`, which is passed to the function
`service_running`, the first argument is always the `instance` which
should be checked. Because all other variables where removed from `$@`
with `shift`.
Before this change the first argument of `$@` was set to the `$service`
Variable. So the function does not work as expected. The `$service`
variable was always the instance which should be checked. This is not
what we want.

"/sbin/wifi up" makes three ubus calls:
1. ubus call network reload
2. ubus call network.wireless down
3. ubus call network.wireless up
The first and third ubus calls call drv_mac80211_setup,
while the second ubus call triggers wireless_device_setup_cancel,
so the call sequence becomes,
1. drv_mac80211_setup
2. wireless_device_setup_cancel
3. drv_mac80211_setup
This commit swaps the order of the first two ubus calls,
1. ubus call network.wireless down
2. ubus call network reload
3. ubus call network.wireless up
Consequently drv_mac80211_setup is only called once,
and two related bugs (#FS3784 and #FS3902) are no longer triggered
by /sbin/wifi.

1. Move code above interface generation
It results in more logical order. Device gets its config section
above interface section.
2. Drop the loop
We have separated code handling bridges now so $device should be
guaranteed to contain a single device name.
3. Drop section name
It's not required by netifd or LuCI & it's not needed by this script

After the commit 43fc720657
("base-files: generate "device UCI type section for bridge"), the wrong
network configuration is generated for the devices that already have the
bridge device section for VLAN, such as the devices in realtek target.
As a result, the bridge device by additional "device" section is
specified to the "ports" option in the "bridge-vlan" section and netifd
shuts down the switch and the ethernet when the network service started.

This switches from the old way of defining bridges in an "interface" UCI
section type (that should be used for layer 3 only). From now a defualt
board switch will have its own "device" UCI section type. It's a new &
preferred way of defining L2 devices.

config interface 'lan'

option ifname 'lan1 lan2 lan3 lan4'
option proto 'static'
option ipaddr '192.168.1.1'

After:
config device
option name 'lan'
