Disabled dot target for now (OS X 10.9 broke my macports, gnn).
Fixed? elsa_pa_stress to work with current code.
Some documentation updating + fixed is_only_visible_router to be bit less suspicious looking.
Added appropriate lsa_changed notifications when neighbor relations change.
Added rather heavy caching of ac_tlv decode results (not elegant, but seems to address major pain point).
Merge branch 'vancouver'

Conflicts:
	elsa_pa.lua
	pa.lua
Fixed unit tests again.
