ANSI test database can now contain multiple test results per version.
We change the syntax of the ANSI test results database to allow the specification of a unique identifier plus other optional identifying information by allowing keyword/value pairs. The keyword :ID specifies the identifier, which should be a symbol. Other arbitrary keywords are allowed which specify additional information to be associated with the symbol specified by :ID in the *ID* hashtable. Not every test failure entry needs to specify this information. In case of duplicates, the last entry wins. Suggested other keywords are :JVM to specify the Java virtual machine, and :UNAME to specify the operating system/hardware combination in a GNU autoconf-like string. See the comments at the beginning of 'parse-ansi-errors.lisp' for more details. The utility has been packaged in ABCL.ANSI.TEST, showing up in the ANSI-COMPILED and ANSI-INTERPRETED ASDF systems loadable from 'abcl.asd'. A database of failures has been included in 'ansi-test-failures'. It is intended that other developers entrich this database with their own test results.
