While fixing things for Flatpak (which have a path deduplicating some
of the path parts) works there, it breaks locating the debuglink in
other places such as GNOME OS.
This tries both forms, using the long form first and then the short
form second, since Flatpak is likely a subset of everything that needs
to be located.
If we have a path like /app/bin/gnome-builder and the debug prefix is
/app/lib/debug then we don't want to end up with /app/lib/debug/app/bin
as the real data directory is /app/lib/debug/bin.
This often works with /usr because /usr/lib/debug/usr can link back to it's
parent. But we should try to do the right thing instead of relying on that
anyway.
We want the traceables to match the selection in either the callgraph or
the flamegraph, depending which is visible. The summary is not currently
implemented for flamegraph as it is already naturally a summary by virtue
of it's colorization.

This will get updated when a node is clicked/updated. The goal here is to
bind it from the SysprofSamplesSection so that the sidebar will update.

If the document is doing asynchronous work after it has been loaded (which
we use a progressbar to denote), then show a spinner for the activity.

We need access to this from the process info but can share the instance.
It sucks to walk the hashtable here, but the alternative is to make these
recursive so that we can check a parent mount namespace.
Until then, take the hit and iterate all the pids to populate them with
the additional device.

If a new process is spawned after the recording has started (processes
spawned *by* sysprof are done before recording starts) then try to extract
information about that process and append it to the recording.
The goal here is to get enough process information to actually decode the
process without creating fork()/exec() amplification.

This is more of what we want to be doing anyway, we don't care about all
the forks in existence.
Additionally, include the comm[] with the pid so that instruments can take
action based on it.
This is by no means perfect, but it gets the kernel tasks running on my
machine out of the profiles. We will no doubt need to add more in the
future, or find a way to record a flag for that in the capture format.
Unfortunately we don't have a good way to do this in GtkScrolledWindow
where you have an initial gravity pulling you to the bottom of a viewport.
We might be able to fake it with a focusable widget, but that sounds like
more work than just animating to the bottom of the viewport.

If we get a request for a process that we have not captured any information
about then give it the "Unknown Process" symbol. That way we do not crash
and we also maintain our invariant of not mutating the hash table.
If we get an empty string, just normalize that to NULL so that we can be
more likely to match equality checks via hash comparison.
Additionally, break hashes out into two so that we can improve the
situation where some symbols do not have paths but still match. This
can happen with bundled symbols.
We only mutate this during loading of the document so that we can be
confident in multi-threaded workers after loading. This just asserts
that invariant holds true.
