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

Example output:
