migrate repack job splitting to SVN

[hufnagel]

CVS:

T0/src/python/T0/JobSplitting/Repack.py
T0/src/python/T0/State/Database/Oracle/ListFilesForRepack.py

Both job splitting algorithm and main data discovery DAO need to be migrated. Some changes need to be made as well.

The job splitting will change to be based on an input fileset and available files. Data discovery is still going to be non-standard though because it filters on closed lumis, ie. just because a streamer file is available does not mean it can be assigned to a job. Another option is to apply that filter in the data feeders populating the repack input filesets. Then we could get by with a standard data discovery based on available files here.

Data discovery also handles run closeout currently, but we might want to move that to a separate query/DAO. It's somewhat easy to return run status in the current query, but the new one it would be a stretch. Better to break up the queries.

Job splitting will stay more or less the same, but we have to rework where the split parameters are defined. Development can get by with reasonable defaults, but eventually they need to come from the Tier0 configuration.
