Clean up configure and new YAC interface

1. Add autogen.sh. The configure script is automatically generated and should not be edited manually. Please, use this new script to update configure when you change configure.ac or anything inside build-aux/m4.
2. Regenerate configure script, which drops several manually introduced lines.
3. The euro5min and aus5min values for the --enable-resolution option seem to be obsolete, therefore they are removed from configure.ac fully.
4. The MO_YAC_FINTERFACE is deprecated starting YAC 3.2.0 (see here) and will be removed in one of the next releases. The configure script and the code is updated to use the new YAC module.
