solver3: Verbose error messages
Introduce a new function, LongWhyStr() that returns a longer
reason for why something is being installed (or not).
This does the same path walk as the other function does, but
it renders the clauses at each level, and one per line, so
the whole output is a lot more informative.
It is a separate function to keep the existing debug messages
use the simple single line implication graph
We remove the other special case in AddWork() for empty solutions
to mke use of the general case in Solve() instead, and then adapt
the case in Solve() to the same case as in Enqueue(). This also
happens to fix the bug that when we encountered an empty clause
we just printed the clause had no solution, but not how we got
to install the package with the clause.
Adapt the test suite for the changes which is an annoying amount
of paperwork.
