  implementation with an array,
- add missing const qualifiers to temporary tal allocators,
- check preconditions with assert,
- remove inline specifier for static functions,

2142094e43 askrene: fix bug, not all arcs exists
We use an arc "array" in the graph structure, but not all arc indexes
correspond to real topological arcs. We must be careful when iterating
through all arcs, and check if they are enabled before making operations
on them.
