more parallel make fixes.

Preparations to fix the engine:
- new function has_been_built(gn), that tells you what's the status of
a given node. Allows us to run Suff_FindDeps later, by updating the number
of unmade children correctly.
- take out the code that handles shell expansions in an expand_children*
set of functions, called by Suff_FindDeps, among others. These must be
called early in the engine to avoid creating bogus nodes.

Engine fixes:
- take the predecessor/successor special handling out, deal with it in
separate functions.
- don't count nodes. Explicitly track them all in a hash table (better
way to deal with non-built issues).
- don't run Suff_FindDeps at start, but just before building an actual node.
This allows make to find all dependencies correctly, as in groff.

Pfiou! now it works.
