Bug Description

Things to do:
- igraph_even_tarjan_reduction, use proper Inf instead of no_of_nodes, otherwise it does not work for weighted graphs.
- igraph_i_dominator_compree always reallocates 'path'
- implement the faster dominator tree finder, this is not actually needed for cohesive blocks.
- error handling in igraph_i_all_st_cuts_minimal_dfs_incb
- igraph_i_all_st_cuts_minimal could return the minimal elements in GammaX
- igraph_i_all_st_cuts_pivot could use adjacency lists, instead of calling neighbors continuously. If it is worth at all.
- implement a non-recursive version of igraph_provan_shier_list.
- simplify igraph_i_all_st_mincuts_pivot by not creating Sbar explicitly.
- some other minor bits, search for TODO in st-cuts.c
