Due to this inadequate bounds check, it was possible under certain
conditions to cause a crash by touching & scrolling in the empty
space "after" the last item of a list.

The viewport used for the scrollbar is allocated on the stack, and falls
out of scope before the next call to set_viewport(), which sets a flag
in the now-out-of-scope "last" viewport.

While using Rockbox for a while on my 1st-gen iPod mini I noticed that
the first entry of a list sometimes displays a wrong character at the
18th column. For example, the ':' character would display as 'z', the
'-' character as 'm', 0x00 would display '@' and so on. Oddly enough
this only occurred when the scrollbar was enabled.
I figured that the call to `display->set_viewport(list_text_vp);` in the
for loop inside `list_draw(...)` causes this. Digging deeper I noticed
that in the `lcd-bitmap-common.c` driver the `current_viewport` was
pointing to the start of the line's text. From what I can tell the
cause of this was that the viewport was set to a struct with a shorter
scope than the entire function.
The actual fix for this is quite straightforward -- once the scrollbar
has been drawn the viewport is now changed back to the default one.

I'm currently running up against the limitations of the lcd_draw functions
I want these functions to be able to be used on any size buffer not
just buffers with a stride matching the underlying device
[DONE] allow the framebuffer to be decoupled from the device framebuffer
[DONE need examples] allow for some simple blit like transformations
[DONE] remove the device framebuffer from the plugin api
[DONE}ditto remote framebuffer
[DONE] remove _viewport_get_framebuffer you can call struct *vp = lcd_set_viewport(NULL) and vp->buffer->fb_ptr
while remote lcds may compile (and work in the sim) its not been tested on targets
[FIXED] backdrops need work to be screen agnostic
[FIXED] screen statusbar is not being combined into the main viewport correctly yet
[FIXED] screen elements are displayed incorrectly after switch to void*
[FIXED] core didn't restore proper viewport on splash etc.
[NEEDS TESTING] remote lcd garbled data
[FIXED] osd lib garbled screen on bmp_part
[FIXED] grey_set_vp needs to return old viewport like lcd_set_viewport
[FIXED] Viewport update now handles viewports with differing buffers/strides by copying to the main buffer
[FIXED] splash on top of WPS leaves old framebuffer data (doesn't redraw)
[UPDATE] refined this a bit more to have clear_viewport set the clean bit and have skin_render do its own screen clear
scrolling viewports no longer trigger wps refresh
also fixed a bug where guisyncyesno was displaying and then disappearing
[ADDED!] New LCD macros that allow you to create properly size frame buffers in you desired size without wasting bytes
(LCD_ and LCD_REMOTE_)
LCD_STRIDE(w, h) same as STRIDE_MAIN
LCD_FBSTRIDE(w, h) returns target specific stride for a buffer W x H
LCD_NBELEMS(w, h) returns the number of fb_data sized elemenst needed for a buffer W x H
LCD_NATIVE_STRIDE(s) conversion between rockbox native vertical and lcd native stride (2bitH)
test_viewports.c has an example of usage
[FIXED!!] 2bit targets don't respect non-native strides
[FIXED] Few define snags

This patch adds a configurable line separator between list items, very
similar to lists in Android. Additionally, below the list item there is a
thicker line. It can be disabled in the settings. Its color can
be configured as well.
Remote and monochrome displays are explicitly unsupported. If there is desire
this can be changed but it doesn't seem useful to me.

Since x is viewport-relative the icon isn't necessarily placed at the physical
display boundaries so that the padding isn't always useful. In fact it does
more harm if one wants to place an icon exactly at 0 of a (non-default)
viewport.
Calling code looks still mostly fine. I've only modified list drawer to include
the padding in the call-site.

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.

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.

in order to make lists reasonably useful without huge fonts.
It's configurable:

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.
