changed tabs to spaces for consistency and fix compiler warnings. Removed assert call (would require assert.h inclusion somewhere).

alignment fixing for USE_SIMD - all memory allocations are rounded

up to 16-byte boundaries. This fixes crashes where the sub-buffers
for complex FFTs end up unaligned violating compiler expectations

Allow setting a suffix for constants and trigonometric functions
...
In order to use constants or trigonometric functions with a type other than
double, a suffix ('f' for float or 'l' for long double) has to be used in C.
This commit adds a preprocessor macro 'kiss_fft_suffix' which can be set to
either 'f' or 'l' and which will be added to floating point constants and to
the trigonometric functions (sin and cos).
Without this suffix, the code will use a too high precision for float and a
too low precision for long double.

Use _mm_free on memory allocated with _mm_malloc.
...
kiss_fft_alloc and kiss_fftr_alloc internally use KISS_FFT_MALLOC to allocate memory, which is defined to _mm_malloc in a SIMD enabled application. Calling free() on memory allocated with _mm_malloc will result in unpredictable behavior. The configuration data allocated with _mm_malloc should be freed with a corresponding _mm_free.
