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.
Thanks I've applied, but some minor comments.

This will need moved to doc/ and converted to our markup format (more on that later).

We should also add a check for GNU octave in configure.ac and a simple script that runs octave and outputs a C file with the new coefficients (by default it should just emit the same coefficients we use today).
Thanks
