5c1432c9cf Coldfire targets: Restore EMAC status after using the EMAC for bitmap resizing. Fixes FS #10412. The tone and EQ filter calculation relies on the proper EMAC mode. EQ filters were not affected because they're set from a different thread, hence FS #10412 only affected the iAudios (coldfire + albumart + software tone controls).

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.

20f76d61ae Make JPEG and BMP scaler optional with HAVE_JPEG and HAVE_BMP_SCALING, both defined for all targets that have HAVE_ALBUMART. Disable JPEG in PictureFlow and pluginlib album art search with 32KiB plugin buffer until PictureFlow 
gets overlay support.

1b13299769 scaler optimizations: 
on sh, use 8.24 fixed-point C math for final division in scaler

on coldfire, use 8.32 fixed-point via emac

on other architectures, use 8.32 fixed-point C math

use shift-and-add to divide when adjusting scale factors in pictureflow

2fbf09752d remove align_buffer from firmare/general.c, replacing with ALIGN_BUFFER macro, and replace all uses of it (only resize.c in core, and pictureflow and mpegplayer plugins), remove it from plugin_api, 
and remove wrapper for it from plugin.h

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.
