Fix for 'multiple symbol definitions' vs 'symbol not defined' dilemna. I think the solution is to wrap the globals in a struct, declare it in a header, and wrap with a definition guard, then define _once_ at library init time. (Sounds like a recipe for something...)

Removed fftw_plan from xtraction functions. Created new init function xtract_init_fft() for creating plans, which have global scope. Updated examples to reflect the change. New configure option: --with-fft_optimisation (0 = FFTW_ESTIMATE, 1 = FFTW_MEASURE, 2 = FFTW_PATIENT).

Dan Stowell: Removed strange "zeroing" part of xtract_mfcc() which was zeroing a load of elements despite the fact that they're ignored by the DCT process called next, and never used for anything. This was writing to an assumed large result array (same size as number of FFT bins) despite the fact that only a small number of MFCCs (typically less than 50) are required, therefore either wasting memory or writing to memory it shouldn't do!

Checked ANSI C89 compliance (basically a few ifndefs for the C99 math functions: powf, roundf etc). Added a few PD examples/tests.

Further updated xtract_spectrum() to hopefully fix fft iteration bug and nyquist/DC inclusion. Added new boolean argument 'withDC' to select whether the DC component is required in the output

xtract_mfcc(): Slightly different way of limiting to XTRACT_LOG_LIMIT. It's the same in theory, but saves on one assignment operation. But the real reason I did it was because my compiler (gcc 4.0.1, Apple intel edition) was getting it wrong (presumably during some optimisation). It does save on the assignment though.
