device manager: Add support for -d cmdline option (driver scan options)
The previous implementation had support to auto-detect devices and to
connect to and pick devices by filling in dialogs, optionally providing
scan options that did not apply to auto-detection. This commit extends
the existing support by introducing a -d command line option similar to
sigrok-cli.
In the absence of the -d command line option, behaviour is identical to
the previous implementation. When -d is provided, the specified driver
is excluded from the auto-detection phase, and another scan is executed
afterwards where the user specified scan options take effect. This shall
result in least interaction and highest reliability of device detection,
while flexibility is increased.
Here are examples of what the -d command line option can do:

device manager: Move filter for supported devices to the scan routine
Move the check for supported monotonic rate devices from the call site
into the actual scan routine.
The scan routine already used to (store and) return a variable length
set of found devices including none, and call sites can cope with this
situation. Pending extensions may call the scan routine several times,
and callers shall not duplicate the extra test condition. While we
expect the specific test for what's supported to change in the future.

The previous implementation supported the selection of an input format
by means of the -I command line option. This commit extends the feature
by adding support for colon separated input format options similar to

This allows users to open files from the command line which previously
became only available after filling in dialogs, and resulted in errors

View: Improve 2a9fcd621 by using settings_restored_
The timer is no longer needed as the introduction of
settings_restored_ allows us to determine whether we
should resize the trace label header to its proper
width when the show event is received.
This is because the show event is received only after
all widget resizing took place. This means that the
header pane sizes will be reliable at this point,
making this solution much cleaner than relying on
a timer repeatedly calling expand_header_to_fit().

Fix #970 by making sure the session state handler can be called
Before, the session did call Session::stop_capture() and fired
the signal to notify of its capture state change. However, the
Session object was deleted before the next run of the Qt event
loop. As the Qt event loop dismisses signals originating from
deleted objects, the connected event handler
MainWindow::on_capture_state_changed() was never called.
To remedy this, we call Session::stop_capture() before the
destruction of the object and force a run of the event loop
immediately afterwards. This way, the event handler is called
and the run/stop button updated properly.

header_was_shrunk() and its return value logic inverted.

Remove Header::BaselineOffset and move arrows as needed instead
The baseline offset was used to keep 5px of distance between
the tip of the arrow and the scroll area. This way, the shadow
that is drawn around the arrow when it's selected won't get
cropped.
However, we can do this differently: instead of always keeping
the empty space around, we make the arrows align at the edge
of the widget space as they should and when they're selected,
we push them aside to the left so the shadow can still be
painted without cropping.
Logically, one would assume that the arrow's label also should
be moving left but I decided against it because this way it
looks as if the arrow didn't actually move, keeping all arrow
labels lined up.

View: Adjust top margin when needed
When the view is big and the traces are vertically centered,
there will be blank space above and below the block of traces.
When the user then resizes the window and makes it smaller,
the white space stays, pushing traces out of the view that
could fit on-screen if the blank space was adjusted properly.
This is what we do with this patch.
If there is still enough space to make everything fit, we
center the traces vertically. If there's not enough space
to make everything fit, we make sure that the top traces
are shown.
Were okay but it showed that there was one case they didn't
cover: the first session receives a resize notification upon
startup whereas all other sessions don't. This means that
sessions restored from a previous run suddenly see the
size_finalized_ variable always staying at false - until the
user resizes the window.
While figuring out how to cover this case, I realized that
there is actually an easier way to perform all this:
instead of keeping an internal state of when and how we
received useless and useful resize notifications, we just
act upon the "show" event, which always comes after all
the widget resizing has been performed. This way, we can
remove the size_finalized_ variable completely and as it
is definitely always received when a session is shown,
we always end up in a sane and correct state.
Note: to reproduce, open up a 2nd session and use demo.
Then, when using the group handle to move the analog traces
upwards, you'll notice that the logic traces will move down
at the same time. This is because size_finalized_ is false
and the view will always center the traces vertically.

Rework signaling mechanism for trace repainting
Before, analog traces would request a repaint of the entire
view when they receive data. To understand how bad this was,
consider 4 enabled analog channels during capture. Every time
one channel would receive a bunch of sample data, it would
force a repaint of the view, resulting in 4 unnecessary
repaints.
To fix this, the analog traces no longer request a repaint
on incoming sample data. Instead, the mechanism now is such
that the view "collates" repaint requests from all used
signalbases by means of a one-shot timer, i.e. any repaint
request is ignored if the timer is already running.
With the timer, we can also establish an upper bound on
how often the trace should update at most, currently 25Hz.
Since this functionality is very useful for any kind of
view, the existing one-shot timer was moved to the ViewBase
and then extended as explained.
