Massage the way it interfaces a bit to make things more flexible.
The chroma_buf scheme on Sansa Connect and Creative ZVx calling the
lcd_write_yuv420_lines implementation in lcd-as-memframe.S with five params
with a chroma buffer that the function can't use wouldn't work anyway so just
have them use the stock implementation (really, how was that working?).

This uses the alpha blending capabilities introduced with anti-aliased fonts
to draw bitmaps with transparency information. The bmp loader is extended to read
this information (pass FORMAT_TRANSPARENT in format). The alpha information will
be used when drawing the bitmap.

This new APIs wrap around lcd_[mono|transparent]_bitmap/_part calls and
handle all kinds bitmaps. The intended use is to draw bitmaps that
come from read_bmp_fd/_file.

- Use the list item centering capabilities in the plugin lib
- Bump plugin ABI for the changed viewport struct (sort the API too).

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

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.

The parameter wasn't used yet and it's not clear whether it should be a absolute or relative viewport.

They work as the drawrect/fillrect pendants but work on a viewport basis; pass NULL to draw the current viewport (the one set with set_viewport()).
In conjunction with action_get_touchscreen_press_in_vp() it should be less of a pain to draw buttons and get presses on them.

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).

Introduce a new .init section for initialisation code, so that it can be copied to an area which is later overwritten before calling. The stack/bss can then overwrite that code, effectively freeing the code size that the initialisation routines need. Gives a few kB ram usage back.
Only implemented for PP and as3525 so far. More targets could be added, as well as more functions.

Increase maximum event count as we need more (I actually had a report about it during custom statusbar testing).
Removed corresponding functions from the core and plugin api. Bump min version and sort.

a) lcd_enabled() is now lcd_active(), and is available for HAVE_LCD_SLEEP only targets (e.g. ipod video) too. It was depandent on HAVE_LCD_ENALE only before
b) rename the hook accordingly, and implement the hook for other other targets too (e.g. the clip [the only mono target with lcd_enable/lcd_sleep yet, so the code is still in the lcd driver], ipod, fuze, c200)

Macros for calculating size needed for bitmap load and scaling, so that
these can be compile-time constant when their inputs are.
Reduce size of bayer dither by chopping all but first row of dither
matrix, and replacing 2D lookup with 1D lookup and small calculation.
Move some functions not related to actual bmp file loading out of bmp.c.
A smaller brightness() for mono targets, and a higher-quality one for
greyscale targets, both replacing the division by 10 with a shift.
Port of the linear and area scalers to greyscale targets, this costs
some binsize but produces better output even when dithered to 2bpp.
Move duplicated row output code from inside vertical scalers to a
separate row output function.
Move some multiplies out of the line scaler, for a small speedup and
code size reduction, as well as a small improvement in accuracy for the
upscaling case.

This prepares for the Clip which will define HAVE_LCD_ENABLE but won't
need the hook since the internal LCD framebuffer is updated regardless
if the display is on or off.
firmware/drivers/lcd-16bit.c has not been modified since HAVE_LCD_COLOR
is obviously defined here

NOTE to WPS people....
%m has been removed, but (i think) because of the other %m tags it wont fail if you try loading a wps with %m|..|, it will just be ignored.
Also note that if the statusbar is enabled the default viewport is 8 pixels shorter than when its not, i.e (0,0) is really (0,8) if the statusbar is shown... I dont think this will be a major issue because almost no WPS show the bar and use bitmaps... text only WPS shouldnt be affected.
