Instead of hardcoding the minimum fraction of possible paths to 0.6, we
take it from the user, and failing that from the consensus, and
failing that we fall back to 0.6.

Previously we did this based on the fraction of descriptors we
had. But really, we should be going based on what fraction of paths
we're able to build based on weighted bandwidth, since otherwise a
directory guard or two could make us behave quite oddly.

Implementation for feature 5956

This way we get the usable nodes themselves, so we can feed them into
frac_nodes_with_descriptors

This is a minimal refactoring to expose the weighted bandwidth
calculations for each node so I can use them to see what fraction of
nodes, weighted by bandwidth, we have descriptors for.

Fix by "ultramage".

This already has a changes entry.

This won't actually break them any worse than they were broken before:
it just removes a set of warnings that nobody was actually seeing, I
hope.

Closes 6826

The implementation is pretty straightforward: parse_extended_hostname() is
modified to drop any leading components from an address like
'foo.aaaaaaaaaaaaaaaa.onion'.

In 6fbdf635 we added a couple of statements like:
    if (test) {
       ...
    };

The extraneous semicolons there get flagged as worrisome empty
statements by the cparser library, so let's fix them.

right on MSVC in ages.
