Fixed bug 26479.  Bug introduced by 0a6f4627; bug not in any
released version.

Fixes bug 26480; bug appeared when we re-enabled the geoip tests on
windows.  Bug originally introduced by our fix to 25787; bug not in
any released Tor.

When I wrote the first one of these, it needed the path of the geoip
file.  But that doesn't translate well in at least two cases:

   - Mingw, where the compile-time path is /c/foo/bar and the
     run-time path is c:\foo\bar.

   - Various CI weirdnesses, where we cross-compile a test binary,
     then copy it into limbo and expect it to work.

Together, these problems precluded these tests running on windows.

So, instead let's just generate some minimal files ourselves, and
test against them.

Fixes bug 25787

Fix a memory leak where directory authorities would leak a chunk of
memory for every router descriptor every time they considered voting.

This bug was taking down directory authorities in the live network due
to out-of-memory issues.

Fixes bug 26435; bugfix on 0.3.3.6.

Hello71 spotted this first.

This appears to be an internal rust thing: I don't know why it's
leaking.  We should investigate further.

These appear to work for me.

If you're owning a C pointer, you need to implement Drop.

These all need C linking to work, and so far, rustdoc does not seem
to respect cargo setting about build scripts or RUSTOPTIONS.

We'd like to feature gate code that calls C from Rust, as a workaround
to several linker issues when running `cargo test` (#25386), and we
can't feature gate anything out of test code if `cargo test` is called
with `--all-features`.

now.

We currently only do the check when we are about to use the HSDir indices.

It was synonymous with the builtin "test" feature.

Just check that smartlist length is zero instead
