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.

07e982df8a cleanup for core-file-in-pluginlib compilation: 
wrapper C files in pluginlib renamed to the same name as the core files they
wrap

pluginlib-only init functions for resize and bmp moved into the wrapper files,
and declared in the associated header files

API() macro removed entirely, in favor of a core-only header file that
redefines core function names to use a plugin_api pointer

some unnecessary uses of PLUGIN in apps/recorder/bmp.c removed

f7fa7e5ad5 Latest work on the bmp on-load scaler: 
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.

adc4848772 Complete rework of the BMP loader: * Support for 4 bit, 15/16 bit and 32 bit BMPs in addition to the already supported 1 bit, 8 bit and 24 bit formats. * Better protection against corrupt BMP files. * Added dithering for 2 bit targets. * Optimised, compact code. There's almost no code size increase for SH1 (only 68 bytes), and even a decrease for coldfire, with all the additional features. * Code policed. * Fixes bug that loading a backdrop worked only once per session.
