f5b7134f59 Consolidate identical fixedpoint exp and ln functions. 
grey_core.c and fixedpoint.c each had their own copies. grey_core.c
can use the ones fixedpoint.c. fixedpoint.c gets the more complete and
optimized version of fp_16exp from grey_core.c.

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).

1d6df54df2 Convert a number of places in core and plugins to use the BIT_N() macro instead of 1<<n. Speeds up things on SH1, and also reduces core binsize. Most notable speedups: 1 bit lcd driver: drawpixel +20%, drawline + 27%, hline +5%; jpeg viewer: +8% for 1/8 scaling. Other targets are unaffected.

11ad7b4bc8 Move screendump from apps to firmware, solving two nasty firmware-to-apps calls. This required to move the filename creation functions as well. * Fix bug in the BMP header of Clip screendumps. * Add remote screendump for targets with an LCD remote. * Simplify some ifdefs and rename a macro in the sim.

309a3c4590 More compact screendump routines for core and greylib. The core routine might be a little slower for vertically packed mono and greyscale displays, the greylib one should be faster in all cases. * Reduce stack usage of greyscale screendump on the Clip* Rename a macro in the bitmap LCD simulation.

0d935ce75e Put the display colours for monochrome and greyscale targets into the target config files, and use them both for the simulator UI and screendumps. The Clip now shows the split display properly in screendumps and simulator. A side effect is that screendumps of ordinary monochrome targets are now 4-bit BMP files (saves an alternate code path, and might be more compatible with some gfx programs). * Simplify the simulation of split display, and also simplify greylib simulation. The simulator now always calculates 129 shades (2*128 for a Clip sim), and just uses 2 (or 4) of those for native display simulation. * Centralised the simulator LCD dimension definition.

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

4a6190dd13 Hopefully fix FS #8840 for iAudio M3, M5 and X5. Reduce greyscale update frequency on M3 in order to reduce CPU load (was >50% before, but this fix would have made it even worse).

8f560bc2b5 Greyscale library: Always use reconstructing inversion, because it's legal to use unbuffered drawing functions in buffered mode, meaning that the chunky buffer might not be in sync with what's displayed. Mpegplayer does this.

32bd0f8ab1 Greyscale library: Optionally put the greyscale ISR on COP on portalplayertargets (only use with the grey_info structure in IRAM atm\!). This speeds up doom by ~50%, and makes mpegplayer work without stuttering audio on targets using it (measured on iPod 2nd Gen and Mini 2nd Gen). It needs corelocking certain functions in the LCD driver on 1st/2nd Gen.

5c87a98b97 Greyscale library: * Implement linearisation curve flipping for 1st/2nd Gen iPods (LCD is inverted when backlight is on, so the curve is also inverted). This needs a slight extension of is_backlight_on() functionality in the core. * Thorough recalibration of all reachable greyscale targets, and #ifdef cleanup. * Reduce on-target gamma a bit, because the displayable contrast range of a monochrome/greyscale isn't that high.

- detection of external power
- compilation of plugins - need to be enabled individually in SOURCES/SUBDIRS

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.
