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.

Include stdint.h only where fixed point types are used. Use min/max values from stdint.h.

This commit adds an `#include` directive for the standard integer
header (`stdint.h`).
