cb9453b475 different approach to independent scrolling, involving ArdourCanvas::ScrollGroup 
The idea now is that a scroll group item can be added to the canvas which will causes its children to scroll in either or both
directions (horizontal or vertical). There are few complications: the position() of the ScrollGroup is ambiguous depending
on whether you want it with scroll taken into account or not, so Item::canvas_position() was added, which defaults to
the same value as Item::position() but is overridden by ScrollGroup to return the position independent of scrolling. This
method is used when translating between item/canvas/window coordinate systems.

Note that the basic idea is that we MOVE the scroll group when a scroll happens. This mirrors what happens in the GnomeCanvas,
where Nick Mainsbridge came up with a great idea that allowed unification of the time bar and track canvases.

87fa554ac9 initial redesign of canvas scrolling to facilitate independent x- and y-axis scrolling of specific groups within the canvas. 
This commit should cause no change in behaviour, but contains all the code and changes necessary
for the next step

6d3b9fe7e6 overwrite state of libs/canvas with code from corresponding period in ardour-cairocanvas 
This makes continued merges with ardour codebase easier, at the
small cost of removing the XML-based constructors. They were not
in use anyway and their use doesn't really fit into the
conception of the canvas as a dynamic UI element. Could reintroduce
them at a later date.

a37a75a05c do not thin() automation event list on load. 
only thin() when writing automation. This fixes issues with
loading short x-fades (which can be stretched later).

TODO: thinning should not just drop, but interpolate and use
more elaborate logic, compared to A2/MB2 Curve::merge_nascent()

9bbc29c022 panner: backwards compatibility, constrain pan-range in old sessions 
fixes http://tracker.ardour.org/view.php?id=5823#c15686

This is only an issue when loading an old session
(pre 3.5.308 - actual change was 21ca6a10) for the first
time with newer ardour.
Saving and re-loading with ardour >= 3.5.308 fixed this as well.

1685c2bff2 fixed number of steps for symmetric fades: 
Extra steps are all below -20dB vs inverse signal being over -2dB.
linear interpolation -6dB steps is sufficient for the tail.

9e82cb582d fix data loss/file deletion caused by mistaken used of Session::source_by_path() to check if an AUDIO filesource with a given path already exists. 
::source_by_path() was written for MIDI files only. I fixed the call and renamed the two similar functions (one for audio and one for MIDI) to make it more clear.
