While avoiding introducing new terminology (cf. d68002ce).

This reverts commit ca66694b.

Otherwise it's not possible to hide the infobar even after Tor is
connected.

Conflicts:

This should make the window resizeable to any size.

Will-fix: #11192

When using a bridge, the first node in the path doesn't have a
ServerDescriptor. We now handle this case gracefully.

Make sure that onioncircuits can still display useful results without
tor-geoipdb installed.

Based on the patch from Sascha Steinbiss <sascha@steinbiss.name>

'stream' is the internal Tor terminology but 'connection' is a more
common term.

These labels are probably not really needed...

- When not connected to Tor the infobar should always remain visible as
  Onion Circuits is not usable.
- When connected to Tor there shouldn't be any infobar, see c2ff2ef7.

Onion Circuits is probably simple enough not to need an extra
description of what it is about here.

I don't like introducing the 'path' terminology to mean 'circuit or
stream' and clicking on both a circuit or a stream produce the same
effect, so let's simplify this here.

- We shouldn't make a difference between "connected to Tor" and
  "connected to Tor daemon" as this probably doesn't make sense to most
  users. Also, both things are meant to occur simultaneously. See also
  #11290.
- Remove the second sentence as reconnecting automatically is what you
  expect from Onion Circuits and you also have no agency on this.

The way we use Transifex, we need to point Tor people to a POT file in
Git that they can regularly pull. I see that Onion Circuits has no such
file in Git. It's a bit sad to store such auto-generated files in Git,
but it's even more sad to ship software without translations.

This prevents a PyGIWarning on startup

With bad network conditions, stem sometimes sends the circuit closed event twice. When recieving the 2nd
of these events, Tor Monitor used to add the circuit that had beeen removed from the list by the 1st.
Will-fix: 10517

Should-fix: #10516

It often happens that more space than half of the window is needed to display
the circuit names. This commit makes the panes non homogeneous in width and
remove the scrollbar from the left pane so that it adapts to the required
width.

For every stream, tor will send something like:

650 STREAM 3709 NEW 0 www.example.org:80 SOURCE_ADDR=127.0.0.1:42592 PURPOSE=USER
650 STREAM 3709 SENTCONNECT 95 www.example.org:80
650 STREAM 3709 REMAP 95 93.184.216.34:80 SOURCE=EXIT
650 STREAM 3709 SUCCEEDED 95 93.184.216.34:80
650 STREAM 3709 CLOSED 95 93.184.216.34:80 REASON=DONE

If we update the target when we receive the REMAP event, then we replace the
hostname by its IP. In this commit we only update the stream status, but keep
the old target.

We used to compare the new circuit ID with the old stream ID, which
obviously was always false.
