Creates a standard buffer passing, local data passing and messaging
system for processing stages. Stages can be moved to their own source
files to reduce clutter and ease assimilation of new ones. dsp.c
becomes dsp_core.c which supports an engine and framework for effects.
Formats and change notifications are passed along with the buffer so
that they arrive at the correct time at each stage in the chain
regardless of the internal delays of a particular one.
Removes restrictions on the number of samples that can be processed at
a time and it pays attention to destination buffer size restrictions
without having to limit input count, which also allows pcmbuf to
remain fuller and safely set its own buffer limits as it sees fit.
There is no longer a need to query input/output counts given a certain
number of input samples; just give it the sizes of the source and
destination buffers.
Works in harmony with stages that are not deterministic in terms of
sample input/output ratio (like both resamplers but most notably
the timestretch). As a result it fixes quirks with timestretch hanging
up with certain settings and it now operates properly throughout its
full settings range.

* fix potential stack overflow through recursion
* fix using using the scrollbar during active kinetic scrolling animation

The old code was very confusing. The scrolling modes need to be handled
differently, thus a state machine makes sense. Should fix numerious
glitches and be easier to maintain.
NOTE: Behavior is still a bit glitchy with an SBS in use, because the skin
engine sees the touch events earlier than the list code.

The scrolling code cannot differentiate between the BUTTON_TOUCHSCREEN post
from normal touches and the one posted in the timeout callback.
To fix introduce a global special button (BUTTON_REDRAW) that results
in the desired redraw. This existed already as a local kludge for android
and is now generalized.

This adds line padding to lists on touchscreens,
in order to make lists reasonably useful without huge fonts.
It's configurable:
* Automatic (default, line height calculated using a lcd dpi aware function)
* Off (status quo, line height = font height)
* X pixels (from 2 to 50 in even steps)
The automatic setting should/aims to Just Work Out Of The Box on all targets

Don't eat buttons on context change if it was waiting for button release (you did need another release).

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.

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.
