[wakaama-dev] Merging reg_up

[Julien Vermillard <jvermillard@xxxxxxxxx>]

I'm reviewing my branch about automatic registration & update

I think there is a bug:

if a registration update is pending (coap transaction) and taking some time and lwm2m_step() is called then a second registration update could be triggered?
