Check list of dataset names for impossible ones.

Two kinds of checks are done:
- Checks for things that do not make sense. These lead to
  errors and skipped datasets.
- Sanity checks. For these warnings are issued but the user is
  considered to be the authoritative expert.

Checks performed:
- The CMSSW version encoded in the dataset name should match
  self.cmssw_version. This is critical.
- There should be some events in the dataset/run. This is
  critical in the sense that CRAB refuses to create jobs for
  zero events. And yes, this does happen in practice. E.g. the
  reprocessed CRAFT08 datasets contain runs with zero events.
- A cursory check is performed to see if the harvesting type
  makes sense for the data type. This should prevent the user
  from inadvertently running RelVal for data.
- It is not possible to run single-step harvesting jobs on
  samples that are not fully contained at a single site.
- Each dataset/run has to be available at at least one site.

Create the specialised part of the CASTOR output dir name.

NOTE: To avoid clashes with `incremental harvesting'
(re-harvesting when a dataset grows) we have to include the
event count in the path name. The underlying `problem' is that
CRAB does not overwrite existing output files so if the output
file already exists CRAB will fail to copy back the output.

NOTE: It's not possible to create different kinds of
harvesting jobs in a single call to this tool. However, in
principle it could be possible to create both data and MC jobs
in a single go.

NOTE: The number of events used in the path name is the
_total_ number of events in the dataset/run at the time of
harvesting. If we're doing partial harvesting the final
results will reflect lower statistics. This is a) the easiest
to code and b) the least likely to lead to confusion if
someone ever decides to swap/copy around file blocks between
sites.

Update the list of datasets taking into account the ones to
ignore.

Both lists have been generated before from DBS and both are
assumed to be unique.

NOTE: The advantage of creating the ignore list from DBS (in
case a regexp is given) and matching that instead of directly
matching the ignore criterion against the list of datasets (to
consider) built from DBS is that in the former case we're sure
that all regexps are treated exactly as DBS would have done
without the cmsHarvester.

NOTE: This only removes complete samples. Exclusion of single
runs is done by the book keeping. So the assumption is that a
user never wants to harvest just part (i.e. n out of N runs)
of a sample.
