isisd: make the SPF code more modular
The goal of modularizing the SPF code is to make it possible for
isisd to run SPF in the behalf of other nodes in the network, which
is going to be necessary later when implementing the R-LFA/TI-LFA
solutions. On top of that, a modularized SPF opens the door for
much needed unit testing.
Summary of the changes:
* Change the isis_spf_preload_tent() function to use the local LSP
as an input (as per the ISO specification) instead of populating
the TENT based on the list of local interfaces;
* Introduce the "isis_spf_adj" structure to represent an SPF
adjacency. SPF adjacencies are inferred from the LSPDB, different
from normal adjacencies formed using IIH messages;
* Introduce the F_SPFTREE_NO_ROUTES flag to control whether the
SPT should create routes or not;
* Introduce the F_SPFTREE_NO_ADJACENCIES flag to specify whether
IS-IS adjacency information is available or not. When running SPF
in the behalf of other nodes, or under the context of an unit test,
no adjacency information will be present.
* On isis_area_create(), move some code around so that the area's isis
backpointer is set as early as possible.
