plugins code cleanup : moved the duplicated fixed point table loockup based sinus/cosinus functions to fixedpoint.c, removed the bmp size definition in the clock.c|-(useless as the size is already defined in a .h generated with every bitmaps ...)

Optimise EQ coef calculation routines for both speed and size. Move now unneeded fsqrt function to plugin fixed point library in case it'll be needed. Move all fixed point helper macros to dsp.h. Added FRACMUL_SHL macro to facilitate high-precision shifting of 64 bit multiplies and remove rounding from macsr in main thread to make this work as intended.
...
Tested quite thorougly, but as always, be careful with your ears.
