ltq-vdsl-app: add ubus support to get metrics
Add a 'dsl' ubus object with a 'metrics' function to replace the
expensive shell parsing done by /etc/init.d/dsl_control [dsl|luci]stat.
All metrics are gathered by using syscalls. An additional thread is started
to handle ubus events.
$ time /etc/init.d/dsl_control dslstat
real 0m 2.66s
user 0m 0.90s
sys 0m 1.76s
$ time ubus call dsl metrics
real 0m 0.02s
user 0m 0.00s
sys 0m 0.01s
