092c340a20 [1/4] Remove SH support and all archos targets 
This removes all code specific to SH targets

d146970ca1 lcd/grey: Enable viewport fg_pattern and bg_pattern for all bitmap targets. 
Greylib performed a horrible hack and stored fg and bg patterns in other
struct viewport fields. One of them was just removed. So instead of
this hack simply enable the *_pattern fields for mono targets as well,
so that greylib can use them normally.

371c86bf3f Adapt OSD in plugin lib to be greylib compatible. 
Requires addition of viewports and alternate framebuffers to greylib
which are essentially similar to the core implementation except that
the framebuffer can be any size and relationship to a viewport. Drawing
is always fully clipped to the intersecting area.

Adapt oscilloscope.c to the API change. FFT will use the new features
(later update).

Get rid of silly and wrong lcd_bmp_part use in OSD. Remove it from
plugin API (must be made incompatible now).

c1d27d105c Speed up mono bitmap drawing on horizontally packed greyscale targets (greyscale iPods). Average speedup is 80% on PP5002, and 55% on PP502x. * Simplify mono bitmap drawing in the 16 bit driver and the greylib a bit, also giving a slight speedup (3% on PP502x, 1.5% on coldfire).

92785b8f2f Use pre-multiplication in scaler to save one multiply per color component on ARM and Coldfire, at the cost of an extra add/shift in the horizontal scaler to reduce values to a workable range. SH-1 retains the same basic math, as 
the use of 16x16->32 hardware multiplication in the earlier scaler stages saves more than removing the 32x32->40 multiply to descale output.

9eeead922a Optimize hline, fillrect and mono bitmap drawing for chunky displays (16 bit colour and greylib). Speeds up text rendering by 20..45% on colour coldfire, by 30..50% on colour ARM, and is noticeable in archos pictureflow.

23d9812273 loader-initialized global plugin API: 
struct plugin_api *rb is declared in PLUGIN_HEADER, and pointed to by
__header.api

the loader uses this pointer to initialize rb before calling entry_point

entry_point is no longer passed a pointer to the plugin API

all plugins, and pluginlib functions, are modified to refer to the
global rb

pluginlib functions which only served to copy the API pointer are
removed

9058620849 Make scaler output truly pluggable, add an 8-bit greyscale output to 
pluginlib for use with greylib, and add source for a test scaled bmp
viewer using greylib.

40919d7db2 iAudio M3: Optimised LCD driver, with more/better assembly code. Speedup is ~80% when boosted, ~15% when unboosted. Also implemented grey phase blitting. * Adapted the greyscale library, and the plugins using it. * Fixed a bug in greyscale scroll down for vertically packed pixels.

fa7eb56c84 Greyscale library: * Defer application of lcd linearisation + gamma in buffered mode to the actual update. This simplifies the update function (grey_update() and grey_update_rect() now are just calls to grey_ub_gray_bitmap_part()), and makes DRMODE_COMPLEMENT work properly. * Make the simulator version work and behave more similar to the target version.

df5c3e15e8 Greyscale library: * Introduced some extra macros dealing with block size, allowing to write some parts with less #ifdefing. * Optimised grey_update_rect() for horizontally packed LCDs, and unbuffered scrolling.

6a56c14e17 Greyscale library: Changed the internal data format once more (separated pixel values and phases), allowing for further optimisation of drawing, scrolling etc. * Optimised grey phase blitting in the core reduces CPU load on all architectures, most significantly on coldfire. Previous version was too slow to keep up at 45MHz, leading to unwanted graininess (update frequency was halved). Also fixed screendump on 2bpp targets with vertical pixel packing.

feb5b15e9b All-new greyscale library, replacing the old one. Features: (1) Drawing/updating is faster than the old grayscale lib at full depth. (2) Always 129 shades instead of 2..33 shades. (3) No graininess caused by frequent updates (mpegplayer, doom, ...). (4) Needs less memory than the old grayscale lib at full depth. * The tradeoff is slightly higher CPU load in the ISR (frames are calculated 'live') and an extra function in the core. * Ported all plugins which used the graylib to use the new one. * Some slight optimisations for archos and H1x0 LCD update.
