[PATCH] netifd: add debug options to uci

[Florian Eckert]

To simplify netifd development, the logging and debugging options should
be configured via uci, so we could set this also during boot.

New uci config options in '/etc/config/network':

config globals 'globals'
	option mask '1'
	option level '3'

The following options are available for the individual uci options and are
given when the service is started.

Option 'mask':
This option  specifies which messages are output on the stderr.
* SYSTEM = 0
* DEVICE = 1
* INTERFACE = 2
* WIRELESS = 3

In order for the log messages to also appear in the syslog, the output
of the stderr must be redirected by the netifd.

Option 'level':
* L_CRIT = 0
* L_WARNING = 1
* L_NOTICE = 2
* L_INFO = 3
* L_DEBUG = 4

With this option the loglevel of the netifd can be changed. If nothing
is specified, the level is set to 'notice'.
