Remove the hardcoded (and way too small) scroll threshold (the distance moved in pixels before we think the users wants to scroll) and replace it with something based on the actual DPI of the screen.
On Android we call the API for that, on other touchscreens we reimplemented Android's formula (as of 2.2) and calculate it.

This adds kinetic scrolling to to lists on touchscreen targets and RaaA, like all other OSes on touchscreens have.
It's only enabled in the absolute point mode, so for non-touchscreen and in grid mode nothing changes.
Kinetic scrolling means that the list keeps scrolling (but is decelerating) after you leave the touchscreen with the finger.
Redraw interval and deceleration is hardcoded for now but could be made configurable if desired.

Looks much smoother now as you don't scroll by whole lines anymore.
Add some functions lcd driver to enable the line based scrolling engine to draw the lines with a pixel-based y-offset.
This should also allow for a sensible kinetic scrolling mechanism (still a todo).

during scrolling.
However, the existing one is part of the list api, so it shouldn't be overridden
blindly internally, so do the decision in a different but equivalent way.

* Scrolling is now done by wiping over the screen. There's no acceleration or
kinetic scrolling yet though. But it works rather well (previously
you held the edges of the list to scroll).
* Improve scrollbar scrolling so that it keeps scrolling even if you leave the
scrollbar area.
* Hide selection during scrolling
* Prevent accidental hitting of the list title (which means go back) during
scrolling
* Don't go into context menu after scrolling when leaving the screen on an item
In general, it's very much like scrolling in native lists in Android,
except there's no kinetic scrolling and everything is still line based, but with
the feature that the scrollbar enables jumping around in the list and very fast
scrolling.
Thanks to Dustin Skoracki for his ideas and half of the code for this.

Plenty of room to add new action abilities if they are wanted.

This is to a) to cleanup firmware/common and firmware/include a bit, but also b) for Rockbox as an application which should use the host system's c library and headers, separating makes it easy to exclude our files from the build.

%Lt - the title text for the current list
%Li - the icon number. Same order as the CustomIcons list, except the first icon is the "no icon" icon.

Don't scroll text in time_screen(). the lines will be redrawn before scrolling statrs, so they don't scroll anyway.

It probably makes sense to pass off any button presses outside of the list viewport to the sbs, I'll leave that for someone else though

viewportmanager_theme_changed() is called during font loading

The new parent might be smaller than the previous one, causing the old list to not stop scrolling. Full-screen stop scrolling isn't correct either though, so we pick the currnet ui viewport to stop scrolling.
This was actually a bug (attempted to fix in r22610) discovered in the custom statusbar patch, where the lists stopped the statusbar text from scrolling.
