Mainly useful for debugging context managers

Skip tentative addresses, which otherwise lead to binding errors and
ignore addresses that are announced as deprecated.

Fixes #83

Otherwise /test/bugs/81 will fail

Fixes #82

Fixed #81

Trying to propagate an error over some unintialized error causes a
warning and, more importantly, an invalid free

Fixes #80

Properly unref cancellable when being done fetching description
document.

- Unref the actual context, not the list
- Free the list element

- Also free list if the manager does not live anymore
- Free the list nodes properly

If we still have filtered contexts in shutdown, drop that reference as
well

Do not assert_not_reached() on errors, but handle timeouts with retry
and other errors like other parsing errors

Remove hack to use warnings with glib development versions

Even if we render the manpage with nonet, should be consistent

It is always better use fixed shebang instead use env command as it
adds come security risk.

We need that for GSSDPClient::address property
