pcp

Accept compressed archive data files

With these changes all PCP client tools are able to directly access
archives with data volumes that have been compressed with either bzip2
or gzip (other compression tools could be added easily if needed for
other platforms).

Because archive data volumes are read in both forwards and backwards
directions, a compressed file must be fully uncompressed to a temporary
file whenever the data file is opened (pmNewContext or data volume
switch).
