e63e84a5df Convert some more stuff to mylcd_ and support pgfx as well.

bc26fe7a96 Add a wrapper header, mylcd.h, in the lib subdirectory, which lets plugins' code automatically call the proper functions depending if compilation is for greylib or color display, also forms proper call to grey_ and xlcd_. mylcd_ub_ call greylib unbuffered routines, regular lcd routines otherwise. Form is mylcd_<fnname>, <fnname> is the symbol name stripped of prefixes lcd_, grey_, or xlcd_. Convert a couple plugins I know well (easy job).

e0af34cb5f More FFT fun: No point in computing and combining the 2nd FFT if it's just being made null. Use the regular complex FFT (called by fftr anyway) and save ram and computation for a given number of bins.

7e538995a5 FFT plugin: Some speed regulation for too-fast targets. (50FPS)

e208b74915 FFT plugin: give everything in the main file a nice 'static'-ing. Saves approx. 1-3K size depending upon the target and so should speed it up a bit.

ff2d224ae7 FFT Plugin: Should use scale_factor, not LCD_WIDTH/HEIGHT to break the spectrogram loop.

30e2f42c82 FFT Plugin: Revamp the main code to rid it of 64-bit math. Use 32-bit kiss_fft_scalar because 16-bit integers are generally a poor choice for computation on-target. Simplify display code to speed it up. Add logarithmic frequency display (need keymappings, guessed on some). On dual-core, perform FFT on COP. Add some support function to fixedpoint.c. ... and stuff.

af466f3cbf FFT plugin: eliminate 64-bit math. This should result in faster and probably more accurate calculations.

f7a30a4b08 kiss_fftr appears to perform two real-valued ffts in parallel -- so feed it only one signal of size N/2 (as opposed to splitting a single signal of size N into two interleaved parts which is what it seemed to be doing before)

43264a946f New plugin: FFT, A frequency analyzer plugin 
There is some more work needed:
- Keymaps are definitely not perfect, touchscreen targets are disabled due to no keymap
- There is no manual yet
