Add function generate_sine_wave_raw_mono(). It serves as a single
channel sine wave generator, to provide data for calculation (e.g.
for noise analysis).
The function is similar to generate_sine_wave(), but a lite revision.
It has no dependency on bat channels and target frequency, no malloc
inside, no data conversion from float to integer samples, and supports
one channel only.

The local header file named as "signal.h" causes mysterious compile
error when built with an old glibc.
signal.h:27: error: conflicting types for 'sin_generator_init'
./signal.h:27: error: previous declaration of 'sin_generator_init' was here
signal.h:28: error: conflicting types for 'sin_generator_next_sample'
./signal.h:28: error: previous declaration of 'sin_generator_next_sample' was here
....
This turned out to be the conflict of signal.h; namely, pthread.h that
is included before our local signal.h also includes "pthread.h".
Since our local "signal.h" has a higher priority, it gets loaded
instead of the expected pthread's one. Then we load it again, and it
screws up.
Although it's basically a bug of pthread, it's anyway not good to have
a header file conflicting with the standard header file. So, let's
name it more explicitly as specific to BAT, bat-signal.h, for avoiding
such a conflict.
