Copyright string fixes (bug#15974), version fix for 5.0.17a "certified".

configure.in:
  Change the version identification for the "certified" builds.
extra/comp_err.c:
  Ensure that the license spelling is as expected by the "mysql_copyright" tool.
scripts/mysqld_multi.sh:
  The "mysql_copyright" tool will not change non-C files, so do not mention the license.
