Seppo Ingalsuo b322168438 SOFT: Add SRC coefficients generate tool 
This patch adds the scripts src_std_int32.m and src_tiny_int16.m those
were used to create the conversions matrices for the default and tiny
profiles. The scripts call the included src_generate function that
does the task with help from the filter design and coefficients
export utilities.

The quality and resources consumption of SRC can be customized with
this tool.
