catchup merge

Smoketest change - Added 'sf-find-ATS-worker-root' to build.xml so that the smoketest goes where the worker is expecting it on a individual basis, rather than it being hardcoded to D:\ATS\...

ATS testing on emulator - Renamed properties for lon-engbuild87, lon-engbuild89, and sym-build02 so they are the same as the machine name. Modified the TEMPDIR for c100726 so that it runs smoketests

sf-list-dir - added new tool 'listdir.py' which can exclude a directory and changed the behaviour of sf-list-dir to stop scanning epoc32/build to speed things up.

sf-postbuild - running analysis in parallel with evalid and post-build zipping.

Simplify the create-canonical-sysdef-file target as we can depend on there only being a single sysdef in the supplied reference.

Simplified create-canonical-sysdef-file so that it's just a simple copy.
