Source for a program that writes a wav file of given length

The resulting segment length is incorrect when doing sample
(GST_FORMAT_DEFAULT) seek on audiotestsrc. The reason for this seems to be that
the sample index is first converted to nanoseconds (GST_FORMAT_TIME) and then
back to samples. Due to rounding errors this often produce one sample less than
intended. 
I suggest using gst_util_uint64_scale_int_round instead of
gst_util_uint64_scale_int in gstaudiotestsrc.c when converting from time to
samples.

I've attached a test program that should produce a sine tone in
/tmp/segment.wav with the length as given by the command line argument.
In reality the resulting file is often one sample short.
